Common Dishwasher Problems We Diagnose

A dishwasher problem can leave dishes dirty, create unpleasant odors, or allow water to leak into the surrounding cabinetry and flooring. Some symptoms have a simple cause, while others require testing of the appliance’s electrical, drainage, or water-supply components.

We diagnose many common dishwasher problems, including:

• Dishwasher not draining

• Standing water inside the tub

• Water leaking from the door or underneath the unit

• Dishwasher not filling with water

• Dishes remaining dirty after a cycle

• Glasses or dishes coming out cloudy

• Dishwasher not drying properly

• Cycle stopping before completion

• Dishwasher not starting

• Unusual humming, grinding, or rattling noises

• Detergent dispenser not opening

• Error codes appearing on the control panel

• Unpleasant odors that return after cleaning

Dishwasher Not Draining

A small amount of water around the filter may be normal on certain models. However, a pool of dirty water covering the bottom of the dishwasher usually indicates a drainage problem.

Possible causes include:

• A clogged dishwasher filter

• Food debris or broken glass near the sump

• A blocked or kinked drain hose

• A problem with the air gap or drain-hose high loop

• A garbage disposal connection that is blocked or incorrectly installed

• A damaged check valve

• A failed drain pump

• An electrical or control problem preventing the drain cycle

Avoid repeatedly running the dishwasher when it contains standing water. Additional cycles can cause an overflow or place unnecessary strain on the drain system.

For basic checks you can perform before arranging service, read our guide: Dishwasher Not Draining: Causes and Troubleshooting.

Dishwasher Leaking Water

Dishwasher leaks should be addressed promptly because even a relatively small amount of water can damage flooring, cabinets, and nearby electrical components.

Water may escape because of:

• A worn or dirty door gasket

• A damaged door seal

• A dishwasher that is not level

• A loose or damaged water-supply connection

• A leaking drain hose

• A faulty water inlet valve

• A pump or circulation-system leak

• Excessive suds caused by incorrect detergent

• A cracked internal component

The location of visible water does not always identify the source. Water can travel along hoses, wiring, or the dishwasher frame before reaching the floor. A proper diagnosis may require removing the lower access panel and observing the appliance during operation.

Dishwasher Not Cleaning Properly

If dishes still have food residue after a complete cycle, the problem may involve water circulation, spray coverage, temperature, detergent delivery, or drainage.

Common causes include:

• A clogged filter

• Blocked spray-arm openings

• A spray arm that is not rotating correctly

• Insufficient water entering the dishwasher

• Low incoming water temperature

• A weak or failed circulation pump

• A detergent dispenser problem

• A sensor or control issue

• Dishes loaded in a way that blocks the spray arms

Cleaning the filter and checking that the spray arms can rotate freely are reasonable first steps. If poor cleaning continues, the dishwasher may require professional testing.

Dishwasher Not Filling or Starting

When a dishwasher does not fill with water, possible causes include a closed water-supply valve, a restricted inlet line, a faulty inlet valve, a stuck float, or a door-latch problem.

If the dishwasher does not start at all, the technician may need to examine:

• The door latch and door switch

• The control lock setting

• The electrical connection

• The user interface

• The main control

• Fill and drain components

• Stored diagnostic or error codes

Because several different failures can produce similar symptoms, replacing a part based only on an error code is not always the correct solution. The code should be considered together with component testing and the appliance’s behavior.

Dishwasher Not Drying Dishes

Wet dishes do not always mean that the heating element has failed. Drying performance can also be affected by the selected cycle, rinse-aid setting, water temperature, vent system, fan, sensor, or the type of dishes being washed.

Plastic items commonly retain more moisture than glass or ceramic. However, if drying performance has changed noticeably or the dishwasher no longer heats during appropriate cycles, the appliance should be inspected.

Unusual Dishwasher Noises

Some humming, clicking, and water movement are normal during operation. New grinding, buzzing, rattling, or unusually loud sounds may indicate:

• Debris near the drain or circulation pump

• A spray arm contacting dishes

• A damaged pump component

• A worn motor or bearing

• A loose internal part

• A water-supply or drainage restriction

Stop the dishwasher if the noise is severe, if you smell something burning, or if the circuit breaker trips.

Dishwashers We Service

APA Appliance Repair works on many standard and compact built-in residential dishwashers. Service availability depends on the brand, model, age, installation, and availability of replacement parts.

Visit our appliance brands page to see the primary brands we service. When scheduling, please provide the dishwasher brand, model number if available, and a description of the problem.

What to Expect During Dishwasher Service

The service process normally begins with a discussion of the symptoms and any error codes you have noticed. The technician may then inspect the dishwasher’s filter, drainage path, water supply, door system, electrical components, pumps, sensors, and controls as appropriate.

The objective is to identify the cause of the problem before recommending a repair. If a replacement part is required, its availability depends on the dishwasher model and manufacturer.

Please remove dishes and items stored directly in front of the dishwasher before the appointment. Access to the sink cabinet may also be necessary because dishwasher water and drain connections are commonly located there.

Should You Repair or Replace the Dishwasher?

Repair may be practical when:

• The dishwasher is otherwise in good condition

• The problem is limited to a replaceable component

• Compatible parts remain available

• The repair cost is reasonable compared with replacement

• There is no significant rust, structural damage, or repeated leakage

Replacement may be more appropriate when the dishwasher has several major problems, extensive corrosion, unavailable parts, recurring leaks, or a repair cost that is too high relative to the appliance’s age and condition.

A diagnosis provides the information needed to make a more informed decision.

Dishwasher Safety

Stop using the dishwasher if you notice an active leak, smoke, a burning smell, sparking, or repeated circuit-breaker trips.

If water is actively leaking, turn off the dishwasher’s water-supply valve if it is safe and accessible. Disconnect electrical power only if you can do so safely without standing in water or touching wet electrical components.

Do not pour chemical drain cleaner into a dishwasher. It may damage dishwasher components and can expose the technician to hazardous chemicals during service.

Use caution when inspecting the filter area because broken glass or other sharp debris may be hidden in standing water.
