Question about Whirlpool GU1100XTLB / GU1100XTLQ / GU1100XTLT Built-in Dishwasher
My Whirpol dishwasher fills the water but does not wash. I hear a sound that it is washing, but when you look inside looks like the spray arms did not move at all.
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:
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.
