Marian for Model Number SHU5315UC [last digits blurred] My 1998 Bosch dishwasher starts off any cycle with the 2H error signal then jumps down to 99 and counts back from there. At 1 it keeps on running and never stops running until I press the cancel/drain combo.[ it drains well and all filters are clean] If I don't catch it right away and it runs a long time, I open the door to find very sudsy water at the bottom which I assume is the rinse agent being washed out and repeatedly recycled as this happens even if the dishwasher is run empty with no detergent. I just detected that the water is not getting heated hotter than our very hot tap water. Also every time the door is opened then closed mid cycle and the start button repressed the timer jumps back to 99, 84, or 51 depending on below which of those three numbers the cycle was when the door was opened. I tried to run the test cycle but couldn't get it to respond. The control module was replaced in 2008. Is this the problem again or is it the heating apparatus? Thanks.
Answer Marian, The 2H error is a heater error. You will want to check the heater and thermostat to make sure that they are good and check to make sure that the control board is sending power to the heater. You will also want to check the wire harness that goes from under the unit at the bend where it goes into the door. There may be a broken wire in that area that would cause this issue as well.
