This time, the main symptom is that the pump that forces the water through the rotors no longer does so continuously, but intermittently.
It goes: dsshhhhhhh - dssshhhh - dsshhhhhhhhhhhhhhhhhhhhh - dshsss - dshhhhh.
It rarely pumps continuously for more than a couple of seconds. It's as though the power to the pump were being disconnected momentarily at random intervals.
I guess it could be a bad connection, but I wonder if it's more likely a fault in the controller board.
Could it be a bad pump?
I'm loath to give up on this damn thing, partly because I have little confidence in finding a new one that's compatible with a six-year-old IKEA dishwasher front panel, and partly because I have spent so much time and effort on it already.
Thanks,
Daniele
