Our 3 year old Bosch dishwasher has developed the following fault: At the end of the cycle, the pump will run continually, even with the door open. Tried a reset, by holding down two of the programme buttons, and this has no effect, other than the "end" LED lighting up. Pulled the unit out to have a look at the pipes etc, and this cured the pump problem, until the end of the next wash cycle, where the problem showed up again. Is the pump on a "timed" cycle at the end of a wash, or is there some sort of sensor that tells the controller when the machine is empty of water?
Cheers
