I checked. There is no sheet of any kind inside or below the door of my Whirlpool dishwasher.

In any case, opening up the non-washing washer revealed that the filter behind the chopper assembly was clogged with food. I cleaned it off, put the thing back together again, and it was washing dishes again, until about three days later. I took it apart again and found food clogging the filter behind the chopper. I thought the chopper wasn't chopping, so I replaced it. It was around $16. About three days later it wasn't washing dishes again.

Further examination (dis-assembly of the sump motor and impeller) revealed that the end of the impeller (which is designed to engage the chopper) had broken off, thus the chopper no longer spins with the sump motor. The impeller costs about $20 and isn't too hard to replace, as long and you keep track of what you've dis-assembled and put it back together in reverse order.

On whirlpool dishwashers, the sump motor drives the impeller (it's connected via the threaded end of the motor shaft) and the impeller, in turn, drives the chopper. The chopper you can replace from inside the tub, without removing the dishwasher from its home or taking apart the sump assembly. But save your $16, as that probably isn't what is wrong... The impeller, being screwed onto the motor shaft, requires complete removal of the dishwasher so that you can completely remove the base assembly that holds the motor assembly.

If you have a GU-series whirlpool washer, the tech manual can be found here:$FILE/8178022.pdf

It has complete instructions for the replacement of every part.

For those of you where water fills, and it just hums, there is a white connector near the back middle that can unplug when you shove the dishwasher back into the slot. Plug it back in, tape the wires up and make sure hoses are out of the way, put the dishwasher back in, and the problem may be resolved.

It looks like there is not enough water pressure to spin the spray arms. Loss of pressure may be due to various things, like damaged seal, cracked tubes, clogged filters, screens etc.
I suggest you take a look at the technician repair sheet that should be stored inside the front panel at the bottom of the door. Remove that panel under the door with screw driver. Inside, attached to the panel, you should find a troubleshooting guide and solution for technician. But it is easy to follow. Look at the section under "poor wash" and follow its recommendation.
Good Luck

Whirlpool dishwasher wont wash

if the bottom tub is filling with water but not washing the issues is with the wash motor, some of this model use a start capacitor that can fail, if it has a capacitor on the side of the motor it may have failed but are difficult to diagnose but are cheap to replace so worth trying, if this doesn't help or if it doesn't have a capacitor then the fault is with the wash motor.

Sounds like glass fragments against the pump impeller. This may jam the impeller and reduce water pump volume giving poor wash performance and possible inability to evacuate the wash tub. It will not go away and may cause the impeller to fail. Remove screens and get the glass out. Do not poke around with your fingers unless you like cuts.

Dish washer fills and then drians without washing

If you're sure it is heating the water, then it sounds like the wash motor/pump has failed. If you've worked on washing machines and/or dish washers before, this is potentialy a DIY job - the Haynes Dishwasher manual is very good, and parts can be found on the internet.

The reason for cheking it is actually heating the water is that the symptoms sound very similar to those of a failed heater = fill, pause, empty, stop usually accompanied wth an error code. Error code will be presented by a number of flashes of a lamp, or a number on a display panle depending whch machine you've got.

Dishwasher will not run after filled with water

The float switch in the tank is bad,also if water only trickles in your fill valve is going bad which will not let it fill all the way to start wash cycle. Fill tub with pot of water to raise float, if wash cycle starts,replace fill valve,if not,replace float switch.

Whirlpool Gold model GU1200 will not start wash cycle

FYI, for anyone else with the same symptoms. I took mine apart and found that the seal on the motor shaft failed and over time corroded the motor shaft bearing causing it to failed. I ordered full motor assembly from the parts store.

Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be about 1/4 to 1/8 inch below the heating element. If not there..replace water inlet valve.

More likely: the solenoid which directs the water to either the drain or the spray arm is clogged/jammed. Located underneath near the drain line.
