Kitchenaid Dishwasher not draining
Clogged Sump Filters
There is usually a course and fine filter. If they are clogged, you will get low water flow and poor washability. To clean filters, remove them and wash with soap, warm water, and brush. If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.
KitchenAid Dishwasher Drain Pump
The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.
KitchenAid Dishwasher Control Board
A dishwasher’s control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the drain pump, preventing it from drawing the water out of the tank and forcing it through the drain hose to the garbage disposal or sink drain pipe.
KitchenAid Dishwasher Drain Impeller
The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.
KitchenAid Dishwasher Drain Solenoid Kit
The drain solenoid opens the drain valve to allow the water to exit the dishwasher. If the drain solenoid fails the valve will not open causing the dishwasher not to drain.
KitchenAid Dishwasher Drain Valve
Over time, the drain valve can get clogged with debris. To ensure that water can flow through the drain valve, clean out the valve. If the drain valve is clear of debris but it still won’t actuate, replace it. Drain valves are not repairable—if the drain valve is defective, you must replace it.
KitchenAid Dishwasher Main Control Board
A dishwasher’s main control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the drain pump, preventing it from drawing the water out of the tank and forcing it through the drain hose to the garbage disposal or sink drain pipe.
KitchenAid Dishwasher Pump and Motor Assembly
The motor drives an impeller to force water out of the drain hose. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won’t run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.
Clogged or Improperly Installed Garbage Disposer
If the garbage disposer was installed recently, the drain plug may not have been removed. All garbage disposers are sold with a solid plug in the drain tube. If the dishwasher is not connected to the garbage disposer, the plug must remain in the drain tube. However, if the dishwasher is connected to the garbage disposer, the plug must be removed. If the garbage disposer wasn’t replaced recently, it is possible that the disposer is clogged. Remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won’t drain.
KitchenAid Dishwasher Drain Hose
The drain hose might be clogged. To unclog the drain hose, remove the drain hose from both the dishwasher and the sink drain and clean it out. The drain hose is most commonly clogged near the garbage disposer or dishwasher drain branch tailpiece.
KitchenAid Dishwasher Check Valve
The check valve prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. If the check valve is stuck closed, try cleaning it out and then replace it if necessary.
KitchenAid Dishwasher Check Ball
The check ball is a small plastic ball in the check valve that prevents water from returning to the dishwasher after the dishwasher has drained. If the check ball gets stuck, it will prevent water from draining through the check valve. If the check ball is stuck, try to free it.
KitchenAid Dishwasher Filter Assembly
A dishwasher’s filter assembly usually consists of both a course and a fine filter located in the sump. If one or both of these filters is clogged, the appliance will probably not drain properly. If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.
KitchenAid Dishwasher Screen Filter
A dishwasher will usually have both a course and a fine screen filter located in the sump. If one or both of these filters is clogged, the appliance will probably not drain properly. If the filters cannot be cleaned effectively or if they are damaged, they will need to be replaced.
KitchenAid Dishwasher Strainer
Dishwashers will use a strainer located in the sump to catch food particles. If the strainer is clogged, the appliance will probably not drain properly. If the stainer cannot be cleaned effectively or is damaged, it will need to be replaced.
