Question about Whirlpool Dishwashers
This repair works for an older Whirlpool dishwasher, but I think several other brand-names use the same design as this brand/model and the fix could apply to them too.
I had a large leak coming out the front of my Whirlpool Quiet Partner II dishwasher this week. Some of the fix-it websites online said the likely cause was a crack or split seam in the lower spray arm; but upon inspecting it I found no problem there. Further, I discovered a seemingly inexplicable discrepancy when I ran the dishwasher with the spray arm off: it didn't leak at all then; but when I put the spray arm back on it leaked bad just like before.
What I discovered upon looking more closely with the spray arm off was this: there were severeal stainless-steel screws that hold the round top onto the pump/impeller housing, creating a gap between the two. I tightened the screws back down and ran the thing with spray arm back on, and presto! No leak.
I concluded with the spray arm on, there's enough back pressure that water was shooting out through the gap at the front of the housing, aiming directly at the hinge gap inside at the bottom of the door. But the reason it didn't leak with the spray arm off is because all the water was able to shoot up freely with no back pressure forcing water out the aforementioned gap.
You need a T-15 Torx bit to tighten the screws down; I'd advise doing that by hand instead of with a power screw-driver: a power tool will have enough torque that you can crack the plastic around the screw hole--which in fact I did, though not enough of a crack to create a problem.
I'll post photos and a video showing all this. Hope this solves your problem like it did mine.
PS After I fixed the leak I got curious and took all 8 screws off and removed the round top piece, and found there's a black rubber seal/gasket that helps prevent water leaks, and a small piece of glass from some broken glassware earlier had wedged itself up under the rubber gasket. Probably not enough to prevent it from sealing sufficiently; but it might be a good idea while you're there to check that the gasket is in place and not compromised by foreign matter. And while you're at it, inspect the drain inlet fins below: I found a large piece of a broken wine glass, two metal screws, and chunks of paper residue from labels that had gotten washed off. Had to use tweezers to pull all that junk out. It would be potentially disastrous if some of that stuff had gone deeper and wrecked the pump . . .
