I have a BOSCH CLASSIXX dishwasher – quite old E-Nr SRS43C02GB/20 which runs for five minutes or so and then it stops and all the lights go out. If I leave it switched on it will start again eventually and run for a minute and stop again. I am using hot fill only.
The machine takes in plenty of water – I have checked the inlet pipe & mesh filter. I’m not sure how to get the plastic bottom off the machine so access to pumps is difficult, but I have checked the impeller of the drain pump via the removable plate in the sump and was ok, but cleaned out anyway. If I take the left side panel off I can lift the flood switch and force the machine to pump out which it does ok. The door seems to shut ok and no loose wires on the door switch or controller. Also removed the syphon break matrix and cleaned it out to make sure the red float in the top was free to move.
Any ideas?
