Dishwasher Won't Drain

Finding dirty water at the bottom of the dishwasher after a cycle is one of the most common dishwasher complaints. Possible causes include:

• Clogged dishwasher filter
• Blocked drain hose
• Failed drain pump
• Foreign object inside the pump
• Improper drain hose installation
• Garbage disposal connection problem
• Defective control board
• Damaged wiring

A small amount of water in certain areas of the sump may be normal on some models, but significant standing water after a completed cycle usually requires investigation.

Simply replacing the drain pump without checking the rest of the drainage system may not solve the problem.

Dishwasher Is Leaking Water 

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

Leaks may originate from several locations.

Common causes include:

• Worn door gasket
• Loose hose connection
• Cracked or damaged hose
• Faulty water inlet valve
• Leaking circulation pump
• Drain pump leak
• Damaged spray arm
• Excessive detergent or suds
• Door alignment problems
• Tub or sump seal issues

The location of the water does not always reveal the actual source of the leak. Water can travel underneath the appliance before becoming visible.

Our technician can inspect the dishwasher and identify where the water is coming from.

Dishwasher Is Not Cleaning Dishes Properly

If dishes remain greasy, cloudy, or covered with food after a complete cycle, the dishwasher may not be circulating water correctly.

Possible causes include:

• Clogged spray arms
• Dirty filter
• Weak circulation pump
• Water inlet problem
• Low water temperature
• Heating system failure
• Detergent dispenser problem
• Improper loading
• Failed wash motor
• Electronic control issue

Before scheduling repair, make sure dishes are not blocking the spray arms and that the filter is reasonably clean.

If cleaning performance continues to decline, a mechanical or electrical problem may be responsible.

Dishwasher Won't Start 

A dishwasher that appears completely unresponsive can have a number of possible faults.

These may include:

• Door latch failure
• Defective door switch
• Control panel problem
• Main control board failure
• Electrical supply issue
• Damaged wiring
• Thermal protection device
• Start button or user-interface failure

On many dishwashers, the control system will not begin a cycle unless it detects that the door is securely closed.

A technician can test the relevant components rather than replacing the control board based on symptoms alone.

Dishwasher Stops Mid-Cycle

If your dishwasher starts normally but stops before completing the wash cycle, the problem may involve:

• Door latch or switch
• Circulation motor
• Drainage system
• Heating system
• Electronic control board
• Wiring connection
• Temperature sensor
• Water supply

Intermittent problems can require additional diagnostic testing because the appliance may appear to operate normally during part of the cycle.

Dishwasher Is Not Filling With Water

A dishwasher cannot clean properly if the correct amount of water never enters the tub.

Potential causes include:

• Faulty water inlet valve
• Restricted water supply
• Float switch problem
• Door switch failure
• Control board issue
• Damaged wiring
• Clogged inlet screen

In some cases, the dishwasher may sound as though it is operating even though very little water has entered.

Dishwasher Is Not Drying Dishes

Wet dishes at the end of every cycle can indicate a problem with the dishwasher's heating or drying system, although drying performance also depends on the model and selected cycle.

Possible causes include:

• Failed heating element
• Faulty temperature sensor
• Vent or fan problem
• Control board failure
• Incorrect cycle selection
• Rinse aid issues

Some modern energy-efficient dishwashers use condensation drying instead of a traditional exposed heating element, so drying behavior varies considerably between models.

Dishwasher Is Making Loud or Unusual Noises

Dishwashers naturally produce sounds as water circulates and drains, but new grinding, buzzing, rattling, or squealing noises may indicate a problem.

Possible causes include:

• Foreign object inside the pump
• Damaged circulation pump
• Drain pump failure
• Spray arm hitting dishes
• Worn motor components
• Loose internal parts
• Water inlet valve noise

If the sound suddenly becomes much louder than normal, stop the cycle and check whether a utensil or dish is interfering with a spray arm.

Persistent mechanical noises should be diagnosed before additional damage occurs.

Dishwasher Has Standing Water in the Bottom

Standing water is often related to drainage, but the source can be elsewhere in the system.

A technician may inspect:

• Filter
• Drain pump
• Drain hose
• Check valve
• Garbage disposal connection
• Control system
• Household drain connection

If a new garbage disposal was recently installed, the dishwasher drain connection should also be checked because installation issues can prevent the dishwasher from draining.

Dishwasher Door Won't Latch

A dishwasher generally will not operate if the control system cannot confirm that the door is closed.

Possible causes include:

• Broken latch
• Defective door switch
• Misaligned door
• Damaged hinges
• Rack interference
• Worn door components

Door alignment problems can sometimes also contribute to water leaks.

Dishwasher Displays an Error Code

Modern dishwashers can detect problems involving water supply, drainage, heating, leakage, motors, sensors, and electronic communication.

An error code is useful diagnostic information, but it does not necessarily prove that a particular component needs replacement.

For example, a drainage-related code could result from a failed pump, blocked hose, foreign object, wiring problem, or control issue.

When scheduling service, provide the error code and model number whenever possible.

Clean the Filter

Many modern dishwashers have a removable filter at the bottom of the tub.

Food particles and debris can accumulate there and restrict water circulation or drainage.

Check and clean the filter according to the manufacturer's instructions.

Inspect the Spray Arms 

Food debris and mineral deposits can clog the small openings in spray arms.

Make sure the arms can rotate freely and are not blocked by large dishes.

Use Dishwasher Detergent

Use detergent specifically designed for automatic dishwashers.

Regular hand dishwashing liquid can create excessive foam and potentially cause leaks.

Avoid Overloading

Overloading can prevent water from reaching dish surfaces and may block spray-arm movement.

Use Rinse Aid When Appropriate

Rinse aid can improve drying and reduce water spotting, particularly in homes with hard water.

Run Hot Water Before Starting the Dishwasher

Depending on the plumbing layout, running the kitchen faucet until the water becomes hot can help ensure that hot water reaches the dishwasher sooner at the beginning of the cycle.

Keep the Door Gasket Clean

Food residue can accumulate around the gasket and door edges.

Clean these areas periodically using methods appropriate for the dishwasher manufacturer.
