One day we smelled the typical odour of burning electrical insulation from a motor winding. The dishwasher had been on for a long time, but had not drained. Further investigation revealed some orange seeds, of perhaps unpopped popcorn, jammed in the very bottom outlet. They had not been caught by the filters. I removed these, and tested the system - it still did not pump out the water at the end of the cycle. The solenoid was popping in and out; and I checked this by moving the float sensor. However, it did not kick in the pump out motor. I suspect that the motor is damaged, but not so badly so that a house fuse was blown. I think that the motor may need to be replaced, but there may be something else I can do.?
Try pouring in enough water to cover the screen in the bottom of the dishwasher, maybe a 2 quarts or so, then run the drain cycle. This should prime the pump and at least tell you wether the drain pump is working or not. Just a trick i've heard and worked for me, not my area of expertise however.

Most do. When the dishwasher is operating, they can get to around 85 to 95 degrees which is far hotter than usual sink hand washing temps. The insulation and liners on the cabinet of the dishwasher give off a "hot" smell when they get to full temperatures.
I would start by first shutting off the breaker. Then removing the kick plate ( access panel at the bottom ) and checking the wiring at the junction box for the dishwasher 120vac supply line. This is actually quite common to find a wire connector come loose due to improper fastening and once the unit is in use for a while the connections heat & cool, become loose from normal operating vibrations and burn up from all the added heat caused by "resistance". The end result is no power to the controls. Check it out and post back what you find.

You should have it checked, but in most cases something has gotten onto the heater element and was burned. But DO NOT, just think this, check the element in the bottom,and look for a burn mark on it, if you do not see anything on it or a mark,then assume it is an electrical problem, pump motor, drain motor, and have it checked. Any questions please post back,everyone is happy to help.
I think so. Check for power at the pump. If so is it running. There are seperate pumps for drain and wash. It is also possible the impeller came loose and the motor is running but not turning the impeller.
I believe you, but did you check the nipple on the drain where the hose connects?
My sink drained OK, and when I took the dishwasher hose loose from the sinkdrain it drained great into a bucket.
When I stuck a screwdriver down where the drainhose connects to the sinkdrain, I felt all kinds of resistance. Its now cleaned out and the dishwasher drains again.
Hope this is your problem otherwise you may need a new pump.
Check the drain pump. First, manually initiate drain by pressing the second and fourth buttons on the keypad at the same time. If it pumps out, disregard the rest. If it doesn't at least hum, check for power at the motor.
Remove lower rack, lower spray arm, and screens in bottom, remove all water inside. Check for debris under pump cover in bottom of sump. The drain pump suction is through the hole on the left.
Behind the toe panel on the left is the drain motor, If no debris was found inside, the drain pump may have failed. Remove outer door panel (you may need to remove the two screws on the sides of the control panel.) Remove the metal panel across the top of the motor area , disconnect hose in front of pump, disconnect wires to pump, press tab at top of pump and rotate clockwise to remove pump. The impeller could be loose on the motor shaft, or the motor windings failed.
If it is new- then the fishy smell is almost certainly the motor and circuit boards
'cooking' in- most motorized electrical devices have an initial pong.
However if it persists after say 10/15 cycles
begin to suspect an incipient fault.
