I have a Bosch which has an intermittent problem which only happens now and then. Sometimes during a wash it will just switch off. If the power button is pressed, the on light will flash a few times and a clicking noise can be heard and then it goes off again. if you wait a few minutes and try again it will either do the same thing or it will start up and carry on with the cycle.
Does anyone have any ideas what is causing this or where to start checking for a fault
