WARNING – If you are attempting to repair any dishwasher yourself, be aware that you are working with potentially dangerous electrical currents that can cause serious bodily injury or death. Always remove the electrical power source from the appliance before you ever begin working on it. If you are attempting to repair any household gas appliances yourself, always be sure to turn off the gas that is designated to the appliance before you ever begin to repair it. Be aware that dishwashers have extremely sharp edges and moving parts that can cause serious bodily injury or death. Be aware that there are many other dangers and precautions involved with a dishwasher repair besides those listed above. We strongly suggest that you please read our DISCLAIMER before any further actions are taken or proceeding any further. Think safety first!
Step – (1.) Filter
Troubleshooting the dishwasher’s filter. Some dishwasher models have a self-cleaning filter, if yours does not and the filter is dirty and clogged with food debris, this is more than likely the reason why your dishwasher won’t drain the water from the tub. The filter will be located at the bottom center inside of the dishwasher. You will need to remove the filter from the dishwasher to clean it, using soap and warm water to give the filter a good cleaning. After you have cleaned the filter, reinstall it and try to drain the water out of the dishwasher. If the water still won’t drain out, more troubleshooting will need to be performed. Maintenance Tip – cleaning the filter in your dishwasher should be regular maintenance for optimum dishwasher performance, just as you empty your dryer’s lint filter for maximum air flow.
Step – (2.) Garbage Disposal
If your dishwasher’s drain hose is plumbed into your garbage disposal, you will need to inspect the inside of the disposal for food build up and blockage that would prevent the water in the dishwasher from draining properly. Safety Warning – Never put your hands inside of a garbage disposal, even when the electrical power has been turned off.
Step – (3.) Drain Hose
You will need to disconnect the drain hose from the garbage disposal and the pump, inspect both ends and the hose itself for blockage.
Step – (4.) Drain Pump
Inspect the drain pump ports, impeller and hoses for blockage or lodged debris, such as food particle build up or small pieces of plastic, etcetera. If you do not find any blockage, you will need to diagnose the pump motor to make sure that it has continuity using a multimeter. if the motor has continuity the motor is good. If the motor does not have continuity, the part is bad and will need to be replaced with a new one.
Step – (5.) Drain Solenoid
Troubleshooting the drain solenoid valve, (only used on some dishwasher models,) it may not be opening to let the water drain out. You can test the solenoid for continuity using a digital or analog test meter. If the drain solenoid has continuity it is good. If the solenoid does not have continuity, the part is faulty and will need to be replaced to fix the problem.
Step – (6.) Check Valve
Troubleshooting the check valve, (used on some models only,) to make sure that valve flap is free and not stuck in the shut position. The check ball is located on the inside bottom part of the dishwasher, in the sump housing.
Step – (7.) Check Ball
