Whirlpool Quiet Partner II diswasher leaks

[PaulRan]

I have a Whirlpool Quiet Partner II diswasher that had broken plates inside, I cleaned it up as best as possible and at first had difficulty with draining.  I pulled the drain hose and removed/cleaned the plastic piece that has the anti backwash piece (which had glass in it), now the dishwasher drains, but is leaking somewhere above the plastic piece that you attach the hose to.  I've tried taping the threads on the plastic piece and reattached with no luck.  Ideas?  Should I take it out to the pasture and shoot it?

Hi Paul,

Thanks,

No problem. I updated your first post to include the model number.

Now lets see what we can do to help you with your dishwasher.

Could you provide a better description of where the leak is comong from?
Thank you.

Unfortunately no, I laid the diswasher (door down) to access the back of the unit, the drain hose plugs into a while plastic piece, which I was able to unscrew that has the black rubber pieces that prevents backwash, (that was full of fine broken glass which I cleaned out, it it started draining fine)?  That piece screwed into a black plastic piece with threads, it was dripping water from that general area as best as I could tell and off the motor on the bottom of the unit, so I am unable to tell specifically where it is leaking from  I thought sliding the 4 "shims" that holds the unit, unplugging the power connector, and seeing if I could pull the whole thing out from the inside of the washer to see if I could determine whats going on, but decided I may be biting off more than I could chew.

That's exactly what you do...pull the drain hose off, disconnect the wire harness and slide those 4 tabs to the inside of the motor housing. Be sure to unscrew the white backflow preventer first so the  pump will lift right up into the tub. Then, order a lower seal kit for the pump, as yours is leaking. You should be able to find the kit using your model number in the parts lookup, and there are plenty of Whirlpool dishwasher manuals here to help you  out, especially with your terminology


The broken glass ruptured the seal, so don't bother doing anything else until you have decided if $20 worth of parts beats a new dishwasher. Continue to run it with this leak and it will ruin the motor.

You are the best!  Thanks, I will try that very thing tomorrow, if I can pull it out, then I'll order the part needed.  I did have one other question with this...as stated I unplug the power "harness" and on the opposite side, I seem to recall some sort of "knob" on some sort of rod, (does that ring a bell?) do I have to do anything with that prior to lifting out the unit?

Your help is much appreciated, thanks again!!!  I will try to find the manual on here so I can order what I need!

Yep, that's a harmonic balance rod to minimize motor noise further. It also unscrews from the base. Turn the square end by hand to release it or put a small Crescent to it..

[PaulRan]

Well, pulled the motor, I found a penny, more glass, twist ties, and loads of gunk buildup.  What a mess!  I cleaned up everything as best I could, bunch of what looks like some sort of calcium deposit on the seal, which I cleaned off and it actually looked pretty good.  I ran the rinse cycle, very very little water leaked, then got gutsy and ran a small cleaning cycle, and i'm leaking bigtime again and it's not draining all the way.  I'm thinking with all that buildup broken loose, I'm back to the clogged part before the drain hose again.  I seal really looked good, I can't see that it would be off, but placing the motor back in, it did seem I had a hard time getting all the 4 shims back in place again, but did so.  I'm taking a break, hand cleaning dishes, and going to pull it all apart again and investigate again (after a nap and maybe even tomorrow after the super bowl!)  Your thoughts?

[Repair-man]

You already got my thoughts. Despite your expert appraisal of the seal, it still needs to be replaced.

The kit is shown below and you may click to order

I didn't think this was the seal you were referring to, I was talking about the rubber ring that the motor unit that I removed sits in within the washer itself.

None of these parts look familiar, do I take the unit apart from the opposite end of the motor?  Thanks again.

[PaulRan]

Better yet, I'll get the manual you provided, thanks again

I was talking about the rubber ring that the motor unit that I removed sits in within the washer itself.

 The thick ring around the actual motor housing itself rarely leaks. Since you are not all that familiar with this unit just yet, better get both parts to C.Y.A.
