Question about GE 24 in. Profile PDW7800 Built-in Dishwasher
After each wash there is about 1 cm of water left at the bottom of the interior of the dishwasher.
Hi and welcome to FixYa, I am Kelly.
There is always just a minimal amount of water in the bottom of a dishwasher so that the pump seal does not dry out causing water to run through the pump motor. Usually though it is not visible yet is is possible.
Excess water in the bottom of the tub post cycle are a sign of draining problems however this is a list of what it could be.
1. A partially clogged drain
2. The timer motor is not functioning properly
3. A broken or worn pump impeller
4. Clogged wash arm holes.
Here is what you need to do:
Check your entire drain system. Start at the final outlet and work your way backward to the motor pump connection on the dishwasher.
Suspected areas are.
a. The sink connection outlet is clogged (this can be inside a garbage disposal.
b. The air-gap is clogged in the very top part of the air-gap (Usually located on the back of the sink and is around 3 inches tall) Remove the cover, unscrew the top nut and check under the horse shoe bend inside the plastic top for obstructions. Clean as needed)
c. There is debris on top of the the motor pump housing blocking the inlet drain. (This would be inside the housing of the lower wash arm on the very bottom)
d. The motor pump outlet drain port is partially blocked. (only accessable from the motor pump exit hole after drain hose removal.)
A partially blocked inlet tub drain to the motor pump would also explain why the lower part of the dishes are not getting clean. Additionally you would have spotted dishes post cycle.
When the drain is partially blocked some models use the float level switch in the tub to control the advancement of the timer. If the water does not drain the motor pump continues to run and run and the cycle does not advance until the tub is drained and the float switch senses same. i.e extended cycle
Check under the float assy for debris.
One more thing to check is the lower wash arm holes for debris or obstructions. If the wash arm is retaining water it can drip out after a drain cycle and cause the puddling you noticed.
Thanks for using FixYa.
