We don't seem to have a forum for this, so I'm asking here in case someone has experience troubleshooting these.
Appliance: Whirlpool DU1055 "Quiet Partner I" dishwasher (~5 years old, in home when purchased)
Problem: While away on vacation for ~10 days the bottom of the washer slowly filled with clean looking water and leaked a little onto the kitchen floor. Since then I've noticed that after the whole cycle is complete there is a small water level left just to the edge of the black gasket for the central pump assembly. It is clean enough that I have to stick my finger down there to detect it. Is this remaining level intentional or an indicator of a drain pump issue?
Conditions and actions taken:
1. No problems with the dishwasher before. Cleans well, no gunk in bottom, no grit or film in rinse. We do quick scrape to trash and rinse of plates/bowls in sink while waiting for water draw to reach temp.
2. Typical cycle for us is the 150 F sani rinse, with no drying cycle. The hot rinse is sufficient for drying the dishes and in my experience with other dishwashers drying elements can damage dishware.
3. I checked water pressure again it is in the 70-75 psi setpoint range, but found it spiking into the 100+ psi range at least once over several days. Suspected that perhaps some water was leaking into dishwasher during spikes. So I flattened the system, left a faucet open and checked the thermal expansion tank pressure figuring it needed make-up air--something I had been meaning to do annually anyway. It was running about 25 psi so I reset it to 75 psi to match PRV. Pressure spikes are gone.
4. Have been manually running drain cycle after each load. This is emptying the basin completely from what I see.
5. I'm not seeing any evidence of drain back/leaking check. When the overfill happened before there was no water use occuring at all in attached sinks and the dishwasher had been emptied just before we left.
6. Haven't noticed any new/unusual sounds, never have had any broken items in the washer.
So the main question is whether or not the machine should drain itself fully at the end of a full cycle (minus heated dry)? If the answer is "no" and it maintains a level in the pump assembly (perhaps to protect it from overheat when the drying element runs?) then all is probably good. If the answer is "yes" it should empty fully, then is there some sort of level sensing switch at fault or does this indicate a weakening drain pump? Either of those two could also impact how well it removes wash water before the rinse as well.
