The dishwasher runs, but never seems to wash the dishes!
Make sure you get water to the dishwasher. Check to see if the water
shut-off valve (located under the sink) is open. If you get water to
the dishwasher, but there is still no water inside during the fill
cycle, the problem might be with a faulty water valve (located at the
bottom of the dishwasher, behind the kick panel, on either side), in
which case replace the water valve.
Concerning the drainage issue(left over water at the bottom)
1. Air gap / Drain hoses
If there is an air gap (located in
the sink, near the faucet), check to see if it is clogged. Unscrew the
top cap and see if there is anything blocking inside. Note: If there is
no air gap installed, the dishwasher might not drain properly.
If the drain hose is clogged, the dishwasher would not drain. If there
is an air gap installed, it is very common that a hose going from the
air gap into the garbage disposer is clogged. Remove and clean the
hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it
might not be broken, it is recommended that you replace the belt,
because it is probably too stretched out.
3. Pump
Some models have two impellers inside the pump - one, wash impeller,
takes care of the wash cycles, the other, drain impeller, drains the
water out. If the drain impeller is broken (broken blades, shaft), the
dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to
drain water out. Sometimes the solenoid gets stuck, preventing the
water from draining out. Try to free up the solenoid. If unsuccessful,
you might have to replace the pump assembly.
5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
6. Timer
Replace if defective (note: uncommon problem).
Thanks Ranger but....there is a drain motor AND a washer motor separately. One of our techs changed the drain motor (and the hot and neutral leads are on correctly ), and i personal gutted the whole dishwasher (drain hose , filter , there is no plunger assembly ) and the check valves are clean and clear also.
When i put it into test mode ... and run the wash motor AND the drain motor together, it drains great!! I really think that both motors should run when draining (like the tall tube whirl pool dishwasher) but this one is not running the two together... except when i make it do so in test mode. I'm still thinking and will try to consult with G.E. Thanks Scott
