Hi, sounds like the control module fault ......an over heated pin in the centre of the cicuit board will be black with soot and will need re-soldering. Open door and remove top six screws, pull up and out plastic top panel. After soldering pin ....water will start to heat up. If further problems persist a new module will be needed ......refubished ones are half cost of new! Cheers, Bob.
