Common Dishwasher Problems We Fix

Dishes are coming out dirty or gritty

One of the most frustrating issues is running a full cycle only to find food particles stuck to plates or a gritty residue on glasses. This defeats the purpose of the machine and forces you to hand wash everything. It often indicates that water is not circulating with enough force or that the water is not getting clean enough during the wash cycle. In neighborhoods like Charlestown with older infrastructure, sediment in the water lines can sometimes contribute to this issue.

Clogged or damaged spray arms
Blocked debris filters or chopper blades
Failed circulation pump motor
Water inlet valve not allowing enough water in
Detergent dispenser failing to open
Spray arm diverter valve malfunction

How we diagnose it
We start by inspecting the filter system and the sump area for debris accumulation. We remove the spray arms to check for clogged jets and cracks that might reduce water pressure. We also test the water fill level to ensure the pump has enough water to operate correctly. If the mechanical parts are clear, we check the diverter motor and the wash motor amperage.

What you can do right now
Check the bottom filter of your dishwasher and remove any large food scraps or broken glass. Remove the spray arms if possible and rinse them under a faucet to clear any blocked holes. Run a cycle with a dishwasher cleaner to break up grease buildup.

Dishwasher is not draining water

Opening the door to find a pool of grey, dirty water at the bottom of the tub is a common and unpleasant surprise. Standing water can lead to odors and bacteria growth. This issue prevents the cycle from finishing and can leak out if the door seal is not perfect. In Boston apartments, drainage issues can sometimes be linked to the garbage disposal or the air gap on the sink.

Blocked drain hose or kink in the line
Failed drain pump motor
Clogged garbage disposal connection
Broken drain impeller
Check valve stuck closed
Control board not sending power to the pump

How we diagnose it
We listen to the pump during the drain cycle to hear if it is humming or grinding. We inspect the drain hose for obstructions, especially at the connection point under the sink. We test the drain pump resistance with a multimeter. We also check the air gap or high loop installation to ensure it meets code and prevents backflow.

What you can do right now
Check your kitchen sink drain to ensure it is clear. If you have a garbage disposal, run it to clear any food waste. Inspect the air gap cylinder next to your faucet if you have one, and clean it out. Ensure the drain hose under the sink is not crushed by cleaning supplies.

Water leaks onto the kitchen floor

A leaking dishwasher is a serious concern that can damage flooring, subflooring, and cabinetry. Leaks can occur from the front door, underneath the unit, or at the water supply connection. In multi unit buildings like those in South Boston, a leak can even affect the ceiling of the unit below you, making immediate attention necessary.

Worn or torn door gasket seal
Loose hose clamps or cracked hoses
Leaking water inlet valve
Crack in the tub or sump area
Pump seal failure
Float switch failure causing overfilling
Spray arm splitting and spraying the door

How we diagnose it
We remove the kick plate and run a test cycle while using a flashlight to spot the source of the drip. We inspect the door seal for gaps or brittleness. We check the water inlet valve for slow drips that happen even when the machine is off. We also look for evidence of sudsing which can cause leaks if the wrong soap is used.

What you can do right now
If the leak is active, turn off the water supply valve to the dishwasher, usually located under the sink. Wipe up the water immediately to protect your floor. Check if the door gasket has any obvious rips or food debris preventing a seal.

Dishwasher will not start

You load the dishes, press the button, and nothing happens. The lights might be on, or the panel might be completely dark. This leaves you with a full load of dirty dishes and no way to wash them. This can be caused by simple power issues or complex electronic failures within the door or main control module.

Door latch or door switch failure
Blown thermal fuse
Main control board failure
User interface or touchpad malfunction
Tripped circuit breaker
Loose wiring connection in the junction box

How we diagnose it
We begin by verifying power at the wall and the junction box. We test the door switches to ensure they are closing the circuit when the door shuts. We inspect the thermal fuse for continuity. If power is present but the unit is unresponsive, we test the user interface ribbon cable and the main control board inputs.

What you can do right now
Check your home’s electrical panel to see if the breaker has tripped. Reset it if necessary. Ensure the door is closing firmly and latching. If the control panel has a “Control Lock” or “Child Lock” feature, try holding the lock button for three seconds to disengage it.

Loud grinding or humming noises

Dishwashers should run relatively quietly, especially modern models found in open concept condos in the Seaport District. If your unit starts making loud grinding, buzzing, or thumping sounds, it indicates a mechanical problem. These noises often happen during specific parts of the cycle, such as washing or draining.

Hard debris like glass or bone in the chopper blade
Worn out wash motor bearings
Drain pump impeller damage
Spray arm hitting dishes
Loose mounting brackets
Circulation pump obstruction

How we diagnose it
We identify when the noise occurs in the cycle to narrow down the source. If it happens during draining, we check the drain pump. If it happens during the wash, we inspect the circulation motor. We disassemble the pump housing to look for foreign objects that might be rattling around inside.

What you can do right now
Pause the cycle and open the door. Check if a spray arm is hitting a tall plate or utensil. Spin the spray arms by hand to see if they move freely. Inspect the bottom of the tub for any loose items like silverware or broken glass.

Dishes are not drying properly

Opening the dishwasher to find dripping wet plates and puddles on top of cups is disappointing. While modern energy efficient units rely more on condensation drying than heat, your dishes should still be mostly dry. Poor drying can lead to water spots and bacterial growth on the dishware.

Failed heating element
Vent fan motor failure
Rinse aid dispenser is empty or broken
Thermostat or high limit switch failure
Control board not activating the heater
Loading issues preventing airflow

How we diagnose it
We test the heating element for continuity to see if it has burned out. We inspect the high limit thermostat which is a safety device that can cut power to the heater. We check the rinse aid dispenser to ensure it is releasing fluid. We also verify the operation of the vent fan if the model is equipped with one.

What you can do right now
Ensure you are using a rinse aid product, as this is critical for drying in modern machines. When the cycle finishes, open the door slightly to let steam escape. Avoid overcrowding the rack so air can circulate between items.

Cycle runs too long

If your dishwasher seems to run for hours on end, far longer than the estimated time, it can be a nuisance. This usually happens because the machine is waiting for a condition to be met, such as water temperature, before advancing to the next stage. This wastes energy and keeps you from emptying the clean dishes.

Water inlet temperature is too low
Thermostat or thermistor failure
Heating element not working
Sensor failure detecting soil levels
Timer motor failure on older mechanical units
Control board software error

How we diagnose it
We check the temperature of the water entering the unit. If the water is cold, the dishwasher delays the cycle to heat it up. We test the turbidity sensor which measures how dirty the water is. We also check the thermistor to ensure it is reading the internal temperature accurately.

What you can do right now
Run the hot water faucet at your kitchen sink before starting the dishwasher. This purges cold water from the line and ensures hot water enters the unit immediately. Check if you have selected a “Sanitize” or “High Temp” cycle, as these naturally take longer.

Soap dispenser is not opening

Finding a dissolvable pod or a lump of powder still in the dispenser cup after the cycle means your dishes were washed with just water. This results in poor cleaning and grease residue. The dispenser is timed to open at a specific point in the wash cycle.

Wax motor or solenoid failure
Broken spring or latch on the dispenser door
Dispenser door blocked by a tall dish
Detergent caked in the cup from moisture
Control board not sending the signal
Broken linkage in the dispenser assembly

How we diagnose it
We check the dispenser mechanism for freedom of movement. We test the actuator, often a wax motor, to see if it triggers when energized. We inspect the door liner to ensure nothing is obstructing the dispenser from sliding or popping open. We also check for moisture intrusion that might be sticking the detergent to the cup.

What you can do right now
Make sure the dispenser cup is dry before adding detergent. Check that the dishes in the lower rack are not blocking the dispenser door. Ensure you are not using old, clumped detergent powder.

Safety Notes for Dishwasher Issues

Dishwashers combine electricity and water, creating potential safety hazards if malfunctions are ignored. Additionally, leaks can cause structural damage to your home. We prioritize safety in every repair and advise homeowners to be cautious when dealing with appliance failures.

Immediate safety steps:

If you see active leaking water: Locate the water shutoff valve under the kitchen sink and turn it clockwise to close it. If you cannot find it, turn off the main water supply to the home.
If you smell burning plastic or electrical smoke: Turn off the dishwasher immediately. Go to your electrical breaker panel and flip the breaker labeled “Dishwasher” to the OFF position. Do not use the machine again until it is inspected.
If the unit is overflowing with suds: This is often caused by using regular dish soap instead of dishwasher detergent. Do not add more water. Cancel the cycle and let it drain.
If you see sparks or hear crackling: Cut power at the breaker panel immediately. This could indicate a short circuit in the junction box or control board.
Slip hazards: Keep the area in front of the dishwasher dry. Leaking water on tile or wood floors creates a dangerous slip and fall risk for your family.

Brands We Service for Dishwasher Repair in Boston

We work on a vast array of dishwasher brands. Each manufacturer has unique engineering quirks, from the motor configuration to the logic on the control board. We understand the differences between these brands to provide accurate service.

Whirlpool family and similar designs (Whirlpool, Maytag, KitchenAid, Amana)

These are some of the most common dishwashers found in Boston homes. They generally use a sturdy pump motor and a filtration system that requires occasional cleaning. KitchenAid models often feature advanced spray arms and specialized bottle wash jets.

Food chopper blade jammed with debris
Diverter motor seal leaks
Top rack adjuster parts breaking
Control board relay failure
Circulation pump motor failure

We see these units frequently and carry many common parts. Accurate diagnosis of the diverter system is key to solving cleaning issues on these models.

GE family (GE, Hotpoint, and related lines)

GE dishwashers are widely used in both rentals and renovated kitchens. They often use a specific type of filtration system and heating element. Newer models have advanced bottle jets and steam cycles that require specific testing procedures.

Electronic control board failures
Door latch sensor issues
Leakage from the pump housing
Float switch getting stuck
Drain solenoid issues on older models

GE units often display specific light patterns or codes when they fail. We know how to interpret these to find the faulty component quickly.

Samsung and LG

These brands are known for high tech features and sleek designs. They often use direct drive motors or linear wash systems. Electronics are a major component of these machines, and moisture can sometimes affect the digital displays.

LE or OE error codes related to leaks or draining
Water inlet valve failure
Digital display flickering or unresponsive
Drain pump noise
Case sensor detecting moisture incorrectly

Repairing these units requires a strong understanding of modern electronics and sensor loops. We are equipped to handle their advanced diagnostic modes.

Frigidaire and Electrolux

These brands are common in many apartment complexes and starter homes. They are generally reliable but can suffer from specific wear and tear issues over time. They often utilize a plastic tub design in lower tier models which handles heat differently.

Spray arm support coming loose
Door seal leaks
Circulation motor failure
Heating element burning out
Touchpad ribbon cable corrosion

We check the motor assemblies and heater circuits thoroughly on these units, as they are common failure points.

Bosch and Thermador

Bosch is incredibly popular in Boston condos and open floor plans due to their quiet operation. They use a unique system without a hard food grinder, relying on a fine mesh filter. They also do not have a standard heating element at the bottom, using condensation drying instead.

E15 error code indicating water in the base
Drain pump blockage
Water inlet valve failure
Door spring tension issues
Junction box wiring burnout

Because these machines are so quiet, some contain sound dampening insulation that makes access tighter. We are experienced in servicing these premium European engineered units without damaging the surrounding cabinetry.

Understanding Common Dishwasher Error Codes

Modern dishwashers use error codes to communicate what the computer thinks is wrong. These codes are helpful clues, but they are not the final diagnosis. A code might say “drain error,” but the cause could be a bad pump, a clog, or a bad board. Testing is always required.

i10, 1E, F1 (Water Inlet Error): Usually means the machine is not filling with water fast enough. could be the valve or supply line.
i20, 2E, OE, F2 (Drain Error): The machine detects that water is not leaving the tub. Points to pumps, clogs, or sensors.
i30, AE, E15 (Leak Detected): The safety float in the base pan has been triggered by water. The unit will often run the drain pump continuously.
HE, TE, E3 (Heating Error): The water is not reaching the target temperature or the thermistor is reading out of range.
LE, LC (Water Level Error): The water level is too high or too low, or the sensor is dirty.
PF (Power Failure): Indicates a disruption in power supply. May just need a reset.
CE (Communication Error): The main board cannot talk to the user interface panel.
E24 (Drain Filter/Pump): Specific to Bosch, often means a blockage in the drain filter or pump cover.

Maintenance Tips for Dishwasher Owners in Boston

Regular maintenance can extend the life of your dishwasher and improve cleaning performance. Given the hard water found in some local areas, mineral buildup can be a silent killer of appliance efficiency. Taking a few minutes each month to care for your machine can prevent expensive repairs.

Clean the filter regularly. Most modern dishwashers have a manual filter at the bottom of the tub. Twist it out and rinse it under the sink to remove trapped food and grease. A clogged filter restricts water flow and ruins cleaning results.

Inspect the spray arms. Check the holes in the spray arms for blockages. Seeds, glass shards, and popcorn kernels can get stuck in the jets. Use a toothpick to clear them out. Also, ensure the arms spin freely.

Run a cleaning cycle. Once a month, place a cup of white vinegar in a dishwasher safe bowl on the top rack and run a hot cycle. This helps dissolve mineral deposits and grease. Alternatively, use a commercial dishwasher cleaner tablet.

Don’t ignore hard water. If you notice white film on your glasses, you may have hard water buildup. Ensure you are using a rinse aid. You may also need to add dishwasher salt if your unit has a water softener system.

Scrape, don’t pre-wash. Modern enzymes in detergents need some food soil to work effectively. However, you must scrape off large bones and solid scraps to protect the pump.

Check the door seal. Wipe down the door gasket with a damp cloth to remove sticky residue. This prevents mold growth and ensures a tight seal against leaks.

Run hot water at the sink. Before starting the dishwasher, run the kitchen faucet until the water is hot. This ensures the first fill of the dishwasher is hot, which is crucial for dissolving the detergent pod and cleaning effectively.

Leave the door ajar. When the dishwasher is not in use, leave the door slightly cracked to allow air circulation. This prevents odors and mold from forming in the dark, damp interior.

Frequently Asked Questions

Why is my dishwasher leaving white film on glasses?
This is usually caused by hard water minerals or using too much detergent. To fix this, use a high quality rinse aid and check your water hardness. You can also try running a cycle with a specialized dishwasher cleaner to remove existing buildup from the machine interior.

Is it worth repairing a 10 year old dishwasher?
The average lifespan of a dishwasher is about 10 to 12 years. If the repair cost is less than half the price of a new unit, it is often worth fixing. However, if the unit has rust on the racks or tub, or if multiple major components are failing, replacement might be the better financial choice.

How long does a dishwasher repair appointment take?
Most repairs are completed within one to two hours. Our technicians carry common parts like pumps, valves, and latches to finish the job on the first visit whenever possible. If a special order part is needed, we will provide a clear timeline for the return visit.

Do I need to pull the dishwasher out before you arrive?
No, please do not attempt to move the appliance yourself. Dishwashers are connected to plumbing and electrical lines that can be damaged if pulled incorrectly. Our technicians are trained to uninstall and reinstall the unit safely without scratching your floors.

Why does my dishwasher smell bad?
Odors are typically caused by trapped food particles in the filter or drain hose. Bacteria breed in this organic matter. Cleaning the filter and running a hot cycle with vinegar usually eliminates the smell. Also, check that the drain hose has a proper high loop to prevent sink water from backflowing into the unit.

Can you fix a dishwasher that doesn’t fit the cabinet correctly?
We focus on mechanical repairs, but we can adjust mounting brackets and leveling legs to improve the fit. In older Boston homes, cabinets can settle, causing the dishwasher to shift. Proper leveling is crucial for preventing leaks and door latch issues.

Is there a dishwasher repair technician near me?
If you are located in Boston or any of the neighborhoods listed on this page, we have a technician near you. We schedule our routes efficiently to provide prompt service to our local customers.

Why is water remaining in the bottom of the dishwasher?
A small amount of water in the sump area is normal to keep seals moist. However, if water covers the filter completely, you have a drainage issue. This could be a clog in the filter, pump, drain hose, or air gap.

Does pre-rinsing dishes help the dishwasher?
You should scrape off solid food, but heavy pre-rinsing is actually discouraged for modern dishwashers. The detergent enzymes need food soil to latch onto. If the dishes are too clean, the detergent can become abrasive and etch your glassware.

My dishwasher buttons are unresponsive, what is wrong?
This could be a user interface failure, a control board issue, or the Child Lock is engaged. Try checking your manual to disable the lock. If that does not work, the touchpad ribbon cable or the electronic board likely needs replacement.

What happens if the dishwasher leaks into the floor?
Turn off the water supply immediately. If the water has soaked into wood or subflooring, dry it out with fans as soon as possible to prevent mold. We will repair the source of the leak, but floor restoration may require a flooring specialist.
