two possibilities: open door when in use. check if water is coming out of the spray arms. if it is and at a good rate, then the problem may be the spray arm jets blocked. the spray arms are only rotated by water coming out of the angled jets at their end or is the main circulating pump running ok?

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.

If the washer is not used regularly the shaft can stick to the seals and prevent the motor from spinning. This happens quite regularly for me if I don't use the washer often. You can just take off the bottom panel - after shutting off power to the dishwasher - and access the motor. you should see some fins and then just try to spin the motor by hand. It usually takes about 90 degrees of rotation before the motor breaks free from the seal. You'll have to fight through the spring-like resistance created by the seal-shaft adhesion. After it breaks free the motor spins freely and you should be all set to go. I haven't found a more permanent fix for this other than running the dishwasher more regularly.

SOURCE: dishwasher - no spray arm action
If it is filling with water properly then it sounds like the chopper screen is clogged so that water isn't getting into the pump. You can remove the top of the pump housing and get to the screen and chopper blade to inspect it. Go to sears.com, click on parts and enter your model number and you can view a diagram of the pump parts to help in disassembling it.
If the pump is not clogged then you have a problem with the impeller or motor. If this is the case you can replace the entire sump assembly just about as cheap as replacing individual parts of the pump.
Post back with any questions.

The average life of a dishwasher is 7-10 years. The symptoms strongly indicate a motor pump problem and my personal opinion is if that is the case youd be better to put the money toward a new dishwasher.

If the unit is filling up and pumping out water, as far as you can tell, but the lights and power to the control panel are not constant, then I would have a professional look at the control panel and timer because there seems to be a miscommunication.
