Belt, Water Pump
Although few dishwashers have a water pump
belt, if the dishwasher won't drain there might be a worn or broken
water pump belt. After removing the lower kick panel the motor can be
seen in the front, the water pump belt is on the bottom of the motor.
If the dishwasher won't drain, the drain pump
might be defective. Test the pump motor with an Ohm meter. Drain pumps
are not repairable, if it's defective it will need to be replaced.
The drain impeller is attached to the pump
and pushes the water out of the dishwasher, through the drain tube and
into the garbage disposer or drain line. If the dishwasher won't drain,
the drain impeller might be broken or worn out. Replace both the
impeller and seal at the same time.
Drain Solenoid Kit
If the dishwasher won't drain, the drain
solenoid kit might need to be replaced. The drain solenoid is an
actuator that opens a flap to allow the water to drain.
The drain valve can get clogged with debris
and should be cleaned out if the dishwasher won't drain. If it seems
clear of debris but won't actuate, it will need to be replaced. The
drain valve is not repairable.
Pump and Motor Assembly
If the dishwasher won't drain, the pump and
motor assembly might be defective. 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 dishwasher won't drain and the garbage
disposer was installed recently, the installer might have forgotten to
knock out the drain plug from this disposer. All garbage disposers are
sold with a solid plug in the drain tube for situations where a
dishwasher isn't connected. However, if the dishwasher is connected, the
plug will need to be removed. If the disposer wasn't replaced recently,
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
If the dishwasher won't drain the drain hose
might be clogged. Remove the drain hose from both the dishwasher and the
sink drain to clean it out. The most common place for an obstruction is
at the garbage disposer.
If the dishwasher won't drain the check valve
might be stuck closed. The check valve is a small plastic device which
prevents water from returning to the dishwasher after it has drained. If
the valve gets stuck closed, it will prevent the water from draining.
The check valve is the device that the drain hose is attached to on the
If the dishwasher won't drain the check ball
might be stuck. The check ball is a small plastic ball in the check
valve which prevents water from returning to the dishwasher after it has
drained. If the ball gets stuck, it will prevent the water from
draining also. The check valve is the device that the drain hose is
attached to on the dishwasher.
