I have a bosch dishwasher (SHU33A06UC/22) that's taking forever to wash, over 4 hours. When it does finally come to and end, dishes are not clean, and there is grime left inside the dishwasher. I ran a test by holding the 'Power Scrub Plus' and 'Rinse & Hold' buttons and then pressing the on/off button. The red leds above 'Power Scrub Plus' and 'Regular Wash' start blinking soon right away. From what I understand, these indicate a heater and water filling faults, respectively. The former would perhaps explain the long running cycle, the dishwasher isn't able to heat water to the required temperature, whereas the latter would account for the washing residue staying inside the dishwasher?
Either way, not sure what to do next. :-) Please advise.
Thanks,
John
