I have a Hygena Dishwasher (AHY-8122), it has been working fine for the past four years, but today I turned it on and set it to the first wash cycle. I later returned 3 hours later to find the red power light still on, and the wash cycle still on first cycle!
I then open the machine to find dirty plates and bone dry! It humms like in first cycle. I have check the water supply and it is ok.
I may sound stupid, but is there a water pump inside of it, and do you think it may need changing?
Thanks for your time
