Question about Dishwashers
SOURCE: ge potscrubber 640 dishwasher
You probably have a restricted water inlet valve. It is not allowing the proper rate of flow for the allotted time, therefore not giving enough water to create the proper velocity to reach the top rack.

GE 720 Potscrubber I started with the water puddling in bottom now it progressed to leaking on the floor. I had a repair guy come to my home yesterday and he says a broken seal and my total cost to replace seal and labor is $165 plus tax.
What is the life expectancy? He did not sound too promising about the future of my dishwasher and said he is certain there will be another repair need shortly something related to the water saturating an area underneath the dishwasher?
He reccomended I call Sears and replace with a Whirlpool product. He claimed he put his kids thru college repairing GE products. My husband wants to repair and I dont because of fear of spending more money!

HI. check the following areas for faults.
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.
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.
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
Replace if defective (note: uncommon problem).

Had the same problem with my dishwasher. Took it appart thinking that something was plugging the drain but there wasn't anything. Turns out the cylinoid that has the hook coming out of it to control the flap for the ejection of the water is broken. When looking at your pump, you should see a small flapper valve on the exterior of the pump hooked up to a small cylinoid that when accivated flips a flap in the pump to eject the water out of it instead of letting it circulate in the unit. This is an easy part to replace, but for me, hard to find since my potscrubber is so old. Hopefully your units are newer and you can find this part at your local appliance shop.
