The dishwasher fills with water as it is supposed to but when the wash cycle tries to start all the machine does is hum. It's a sound not unlike a stuck motor. If I hit cancel the machine will drain as it should. Water preasure and motor both seem to be operation normally.
Prior to this the "Clean" button was flashing and I reset it using a sequence found here. It worked fine for several months and now it has started this new problem.

Re: Dishwasher fill with water then just hums
The hum is probably the main pump powered up but not turning. the pump is an induction motor and a usual fault is the motor capacitor. try to access it, find the value of the capacitor and replace. it is a cheap part

sounds like your main circulation pump is not working, if it is humming when it is supposed to start, sounds like it is getiing power, so probably not the control circuits, can you measure voltage to pump? if you are getting 120 there, probably pump motor is dead
If you hear a hum when it should be washing, the motor has seized. Replace motor. If it fills with water and stops quite, run it through a test using the tech sheet under the bottom panel to access. These dishwasher have had issues with the motor.
Air gap is clean Garbage disposal is clean Dishwasher fills with water OK Drain pump runs after a wait of several minutes and seems to run slow but drains most of the water out of the reservoir. Dishwasher is not running the wash cycle (spraying water on dishes)
I have the same problem dishwasher seems to try to wash but not get anywhere. have tried tipping dishwasher to empty excess water out, filters and arms cleaned. dishwasher just takes in water, hums for a bit and then the cycle ends after about 20 mins but obviously dishes are not clean
