My kitchen aide dishwasher has water in the bottom which accumulates about 20 minutes after a cycle is complete. I called a repair who came out and took some debri from the drain and part of a broken class. Prior to doing this, he hit a bottom on the front of the dishwasher and all the water was pumped out of the dishwasher in a matter of seconds. After he left, the dishwasher again had water in the bottom after completing a full load of dishes was washed. This occurred about 30 minutes after the clean dishes were removed. I think the problem is a defective disposal . We bought a new disposal to be put in next week. Until, then do you know what button the repairman pushed to remove all the water from the bottom of the dishwasher. If I knew this, I could continue using the dishwasher. Thanks

If your dishwasher is cleaning poorly, check these:

Water-inlet valve
Internal filters
Drain valve
Spray arms
Water temperature
Detergent cup
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.

When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.

Dishwasher Water Inlet Valve Replacement

Be sure to read and understand any instructions that come with the new water inlet valve.

Tools required:

Adjustable wrench

Multi-Screwdriver

Pliers

After checking all sprayer arms for clearance, and checking heating element and discharge pump, the problem was solved by replacing the small sprayer arm at the top of the washer. This small arm had popped off some time ago - obviously the water pressure was excessive for the small and unimpressive fastener. Luckily we had saved this piece, which I refastened with a strong aluminum non-corroding small bolt. Presto - now the water distribution is back to design specs, with sufficient water coming out under pressure from the mid level arm. Lesson: always look for the simplest cause first with the simplest solution. TCA

Hi Ben. Since you just replaced the disposal, begin by checking the entire length of the drain hose, from the drain pump in the lower front of the dishwasher to the disposal. If that hose is kinked, or has an extreme bend in it, that alone could be the problem. Joe
