Hi. I turn on the dishwasher and slect any cycle and it just makes an electric humming sound. That is there is no immediate water flow. Sounds like a elctrical comms problem or water pump problem. Any clues?

It has been my experience that the humming that you are hearing is from the electric coil and shut off plunger to the incoming water line. Some of these are rebuild-able. Some of them are not. I would suggest to you that you look up your model and serial number along with the make of this model. Pull the unit out from the cupboard and follow the hot water line into the dishwasher. You should find a plastic valve with two electrical wires hanging out of it. Most likely hooked on with spade clips/terminals. (Quick disconnecting electric contacts.) Once you locate this you will know what you need to replace. Remove the broken part and take it into your local parts store or look for the part on line. The model and serial number along with the make of the unit will go a long way in helping you find the part you need. The humming sound also tells me that the transformer is most likely still in operating condition. So this too points directly to this same part. Good luck and good hunting.
Check the drain pump it is located in the front of you unit .Disconnect power or flip breaker .Remove the front kick plate then there is a metal plate above that is held on with 4 screws remove that and reach in and press lever on pump and turn counter clockwise it will come right out .Then check for items in the pump area could be glass. Hope it is helpfull

Here is a tip that will help you to find out why water will not come into the
Dishwasher Trouble No Water entering Dishwasher
Check the incoming water to the dishwasher. If the filter is clogged clean it and re fix. Strainer is located on the machine inlet junction where the hose is fitted.
The humming sound is due to motor running without water. When you rectify the inlet flow fault, pour additional water manually into the wash chamber and run the cycle. This to remove trapped air in the pump due to dry run.
if you have just installed this machine or it has been moved out make sure that the water supply taps are on as the humming sound could be the water selanoids (electronic water vales that allow water to flow) if there is no water in the machine it will not advance, check water selanoid, check to see if another prrogram give the same fault, put your ear close to the machine to see if you can lacalise the sound (never remove the the caseings without turning power off 1st very real chance of electric shock)
Hi. This grinding or hum can be associated with internal electric motor failure. the grinding and humming sounds are warning signs that will ultimately, lead to total failure.The actual term we in the industry use is A.C. hum. This will occur when the internal electric motor windings begin to break apart from the center housing inside the motor casing. this will disrupt the current flow, causing over heating. the grinding is because of the alignment that has been disturbed as well. The solution is to prepare for the replacement of the electrical motor or, you can repair it.
humming noise sounds like a solenoid is not snapping in, this is not something that the average or even above average homeowner can fix. Solenoids go bad, they are a moving part that are activated by electricity, can be dangerous to mess with as water and electricity don't mix. Get a repairman or get a new one.
When the water stops too soon, it could be the "over flow" is stuck in the downward position, therefore the dishwasher thinks it's going to over flow. Check that out. Otherwise I'm afraid this sounds like the circuit board is shot.
