overheating dish washer adp8352?

I have a diplomat adp8352 dishwasher that heats up very rapidly. I can smell a slight burning as if it is over heating. I watched the water filtering in through the see through pipe at the back of the machine and the water is bubbling i have let it go through its cycle but dishes have not been cleaned! also the cleaning agent has not desolved, no water in the tray below as i have just replaced outlet pipe as it had split in.
Can anyone help with this problem, I will be very grateful with any advice.
