JENN AIR DISHWSHER JDB6510 will not drain.

Some dishwashers will now wait before draining final rinse water. This helps the dishes dry. Instead of draining the hot water it will save it for a short time to dry dishes. Wait 20 minutes it should drain after that.

JB, make sure the float assy. is not stuck inside the tub. On the motor harness, you have yellow-main, red-drain grey-wash and blue is the common. Check for power to the motor during the wash cycle. On this model I believe they installed a thermal cut out after series 11. I'll keep an eye peeled for any replies..Catriver.

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.

ok with the soap prime the sink before you start it and clean the dish washer.take a table sppon full of tang put it the dispencer and run the unit this will clean the unit

One of four things is happening...
1. Your drain hose is too low or is too far down the stand pipe and is causing water to siphon out of the machine
2. Your water inlet valve is stuck open and will need to be replaced.
3. The pressure switch (water level switch) has failed and won't switch between fill and wash.
Does it flood the room? If not probably #1.
Does the water stop running when you unplug the washer? If so, #3
Can you only stop the water flow by turning off the house hot and cold valves? If so, #2
4. If none of the above, then you might have a clogged pressure switch hose. It is a hose that connects to the water level switch (pressure switch) on the top end and the outer tub on the bottom end. It may have gunk plugging it up on the tub side preventing air pressure build up to trigger the water level switch. If so, remove the hose from the tub and clean out the end of the hose and the air dome that is attached to the tub. What brand is your machine?

This is not a JDB6510 Model. Check the inside label when you open the door.

yes it could . If you are trying to pump the water 7 feet or more above the floor then it will at the end of the cycle get air into the drain hose causing cavatation, the result when the machines stops is the water running back down the drain hose back into the tub and that is what causes the musty smell.
Lower the drain if possible

You don't want to replace the timer switch just for that. If it is under warranty, get it done ASAP.
If not, wait till you have a real problem with the timer, like it not running, or doesn't cycle completely.
Then the switch will have to be replaced and you'll miss that tick tick ticking.

I would bet that it is the timer switch assy.
Motor runs ? yes
washes? yes
drain tube clear ? yes

If there is no drain valve to deal with, the problem must be the contacts during the timer cycle, since the main obviously works or you wouldn't be able to wash anything.
you need a new timer switch assy.
