Hi all got a caple di453 dishwasher goes nearly all the way through the program fine and then the wash pump starts pulsing about every 5 seconds ,beeps once stops then pulses again . Heater is ok no flood in the base ,just strange that it goes through nearly the whole program fine then at the end it starts doing it,oh and the pump is fine. Any help would be good thanks. I always seem to get the really strange faults.
