Whirlpool 24 in. DU920PW Built-In Dishwasher - Page 2 Questions & Answers
Dirty Dishes
either it's an old unit that needs replacing, or the water preasure in your house is insufficient.
Dishes not getting clean, not sure real sure if
Try a dishwasher cleaning product. Relatively easy to check if the pump is working. Line up both the spray arms front to back and then run a sequence and see if the arms have moved. If they've moved the pump is working
Where to clean the food out
A dishwasher cleaner may help. It usually is for lime deposits but it still may break the stuff down enough to flush it out. Wal-Mart or an appliance store should have it.
Water will not drain after cycles are complete
Start with removing the screws in the bottom of the dishwasher and pull out the filter, etc. Clean everything you remove in a sink and soak in white vinegar anything is coated with minerals.
Inspect closely everything you can now see with a flashlight (watch out for broken glass!) Remove any debris found. Reassemble and test if removing any obstructions found.
If problems continue, run a short cycle and listen closely. When the pump should be running, do you hear the sound/hum of the motor turning (but water is not draining?) If yes, replace the pump motor.
If you hear nothing during the cycle when the dishwasher should be draining, the problem is almost certainly a failure of the timer/controller that controls the pump motor.
Good Luck!
Model # DU1055XTPQ3
WHIRPOOL DISHWASHER
RESET CODE
chris72 had the solution to my Whirlpool DU1055XTPQ3 not turning on. Per Chris's suggestion, I pressed back and forth between sani rinse and heated dry. All the lights came on as it reset and it was good to go. The dishwasher started up immediately. Saved me a service call, THANK YOU Chris!!
Water will not drain from
I had this same problem and called a local repair company. They sent a tech out for a service fee and and hourly rate. This guy could not get one part off under the bottom sprayer to see if anything was clogged and wanted to put a new motor on it. I had him stop and I was left with a dw apart and a bill for $110. About 4 months after he left I decided to try the same and also could not remove the nut above the large plastic nut to see if anything was clogging the unit. Once I could not get this off I decided to try blowing out the line from the drain pipe back to the unit. I did not have a compressor so I used my shop vac and forced air back into the unit from the plastic drain hose. I had a variety of foreign objects come into the cabinet from under the screen unit. This seemed to solve the drain problem. Good luck.
Low or no spray pressure
You sound like you diagnosed it pretty good, so I think you can change the impeller. The biggest problem is making sure everything is lined up so it wont leak after its re-installed. I've never had much luck removing the old impeller without breaking it into pieces. just be careful not to mess up the shaft. If its an older machine, some Whirlpool/Kenmore can have the whole thing changed in one part. Its a little more $$ but it has the motor and all. And its easier and faster!! Also, your pressure problem may be related to the motor.
WP dishwasher
water valve screen on dishwasher could be clogged up or you could have a bad water valve
Dishwasher filles up with water between running it.
sounds like the water valve is leaking.If there is some dirt in the valve it will cause it to not fully seal and shut off. If the hapens water will leak by. Replace the inlet valve and your dishwasher will not fill when its not in use
Black stuff in the bottom of the dishwasher
That black or gray stuff you're talking about is actually a combination of old food particles and soap deposits. The stuff builds up in the corners of the lower front areas of the tub and right under the inside of the door where it closes over the tub front. These areas can develop "scungy" deposits because these are areas that the dishwasher doesn't always clean and/or water remains pooled. A little routine cleaning about once a week around the bottom lip of the door and the door gasket with a damp sponge will prevent this build up. Hope this helps you.
A part fell off............
it looks like it could be the a seal from around the powerclean filter module - the big round thing in the middle of the floor of the machine. check the manual on this link;
http://www.whirlpool.com/assets/pdfs/lit...
page 5 item "k" and you will see what i am talking about - page 20 gives a better idea but nothing is shown as you describe it - it may be a later addition/modification. try and see if it might fit this about, in the area between the filter edge and the floor of the machine.
call:
1-800-253-1301
(if this doesn't work try 866-698-2538 - but i think the first one is the new one) for whirlpool service guys - they are very helpful.
Only other thing i can think is if you had any other item in the dishwasher that may have a similar seal - mixer type machines, pressure cooker lids, storage jars or maybe something the kids wanted to wash etc. - you know what i mean; think hard if you can think of anything - the seal may have been in the machine for a while before you saw it.
I do think the filter is where it came from though - without this seal it may appear to be working but not efficiently, and perhaps it is a little loose and somehow the seal came out. Bit of a guess but if all seems well then there may be no problem - a leak to the outside would be the first indication of any major issue which you say you don't have. good luck.
I hope this helps
