I live in the UK and have a 3 year old built-in Bosch dishwasher, model number smv50c00gb/14. It finished a cycle ok but then started beeping and flashing the "check water" red light. The only way to stop this is to power off at the mains. When I turn the power back on, after a few seconds the light starts flashing. The beeping also resumes and the dishwasher makes a rumbling sound.
I've tried tipping the dishwasher but that didn't help. I've also tried cleaning the filter om the input pipe.
