    Hi Oracle! You seem like you are an absolute Guru on the bosch dishwashers. I have a SHX3AR75UC/27 dishwasher that I have changed the heat pump and the control board so far but have not resolved my issue. The cycle heats the dishwasher and sprays some water around inside the dishwasher but it stops after about 5 minutes into the cycle and the sanitize light flashes and the dishwasher beeps like it is done with the cycle. I do not have any LEDs to indicate error codes besides the sanitize light flashing. Have you run into this issue before? Would love to have your 2 cents! Thanks :)

      Hi Jake
      Can you remove the bottom kick panel and check whether water is pooling underneath and if so can you hear if the drain pump is continuously running

      @@theoracle6005 The drain motor runs but it does not run constantly. There is no pooling underneath the dishwasher, only a drop or so from my supply line. The cycle goes from Draining on start, to filling water, to attempting to wash, i assume the arms spin a little because theres water splashing inside, then it goes to a drain cycle, then another fill cycle and then a short wash (maybe 30 seconds) then the sanitize light starts to flash, and it has 3 short drain cycles (maybe 5 seconds each) and the dishwasher beeps like it's done and the sanitize light stays flashing.

      Hi Jake
      The machine does the following sequence on bosch dishwashers
      1) Drains
      2) Heat pump runs and checks for water in the sump
      2) Inlet Valve Pulses to check flowmeter operation
      3) Then the condenser drain inlet valve fills chamber
      4) Wash pump does a check and starts up
      5) Prewash commences
      Drains
      6) Fill sequence starts and heating main wash begins
      7 followed by rinse phase and final drying.
      Pull off the side LHS panel and tell me if the drain inlet valve is filling water into the chamber , if this fails the machine will display E19 , if machine does not have an lcd , then the led lights flash indicate the fault.
      The drain inlet valve located on the front LHS of the dishwasher close the LHS door hinge rope. You will need to remove the panel to check operation.
      Have a look thru my video.list
