Bosch Dishwasher Cycle Runs Long, dishes not clean
Until last week, our dishwasher ran great, no problems ... then it suddenly started making loud noises towards the end of the cycle and the cycle would not end (over 3 hrs, was not done). We opened the dishwasher door and noticed steam, but the cleaning tab was still in the dispenser (dispenser door had opened but the detergent had not been dispensed) and the dishes were not clean. We attempted to run a 2nd cleaning cycle to wash the dishes ... again the cycle ran long and the dishes were not clean (this time, the water seemed cold inside the dishwasher).
Tried to follow manual instructions to complete a self-test (to diagnose the problem), but the buttons did not light up as the manual indicted they would. Noticed water in the bottom of the dishwasher ... tried to follow manual instructions to drain the dishwasher, but nothing happens. Please help. What part(s) do we need to replace, or should we just buy a new dishwasher?? Thank you.
