Will not pump out dirty water

Our 6 year old dish washer has quit pumping out the dirty water. It runs thru the cycle, it just reuses the dirty water. I have checked the filters and grinder but they seem fine. The drain that it is hooked to is working fine also.

Re: will not pump out dirty water

Is it hooked to a garbage disp. If so make sure the knock out is out. Then if you can use a volt meter. take off the 2 screws at the bottom of the unit on the left side is your drain pump. take off the 2 wires put your meter on ac and put your leads on the wires then run it in a cxl cycle. (the cxl will depend on your unit you will press two buttons @ the same time and hold it it will light up 2(2min))
if you get 110 you have a bad pump........

I have a ADG450 about 7 years old, the problem is there is dirty water left at the bottom of the dishwasher after finishing the cycle and the dishes look as if they have had the final rinse in the dirty...

check the pipe leading from the dishwasher to the outlet, maybe under sink. this needs to be raise up as water will flow back into washer. Had this problem myself, felt foolish when the repair man just tied it up and left. !

Not enough water Pressure to clean dishes, 6yr old Bosch

Replace the pump, if you go through the trouble of repairing the pump and all the disassembly and then more problems will probably ensue. As far as location it is usually located under the washer. Accessed through the front service panel. Make sure you follow all safety procedures #1 being unplug the washer or turn off breaker prior to proceeding.

Water seems to be hot enough, drains properly, arnms not blocked, dishes not being cleaned at end of cycle. Almost seems like it is skipping the wash cycle.

Hi smiller8565,
There is 3 basic problems that will cause a dishwasher to not clean the dishes. You can check these problems and see if any will solve your problems.
1: If there is water or suds left in the dishwasher after the cycle is complete. This will cause dirty water to be used in the final rinse and the dishes will not get clean.
2: The pump that supplies water to the spray arms is jammed or defective and unable to pump the water properly, thus causing the dishes to remain dirty.
3: Timer, the timer is not allowing the machine to work in the wash cycle.
The solutions for these 3 are as follows.
1: check the drain line for blockage, if you have a disposal make sure it is clear and water flows down the drain properly. If you have suds left in the dishwasher, clean them out and run a couple cycles with not detergent to rinse away the old suds.
2: Look down in the bottom for any obstructions in the pump. Popcorn seeds, broken glass, etc.
3: If the unit is skipping the wash cycle you will most likely need a new timer or control assembly.
Good luck and I really hope this will Fix Ya
