Run this test program and see what happens.
To start test program, press and hold both SCRUB WASH and DELICATE/ECONO program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # XXXXX be displayed (e.g./ "21" = version 1 with jumper). When wash program buttons are released, lights above them will flash. To end test program, press ON/OFF button.
To check each program indicator light, press its button. To check Cycle Countdown display, Refill Rinse Agent light and REGULAR WASH light, press REGULAR WASH button (press Delay Start button to test Cycle Countdown display alone). Cycle Countdown display will show "88" when REGULAR WASH button is pressed and "8h" when Delay Start button is pressed.
To start testing, press both the SCRUB WASH and DELICATE/ECONO buttons a second time. When testing has ended, Cycle Countdown display will show a fault using codes below. If more than one fault occurs, code numbers will be added together, (e.g./ "6" = faults 2 + 4).
0 = No faults detected 2 = Heating fault 8 = NTC (temperature sensor) fault
1 = Aqua Sensor ("Sensotronic") fault 4 = Filling fault F = Filling fault (display occurs during wash, not test)
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), display will show fault code "4" and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), display will show "0", water won't heat (to 150ºF) and water won't stop circulating. If NTC probe (f2/f4) has failed (opened), display will show fault code "8" immediately and testing will end shortly after water has started circulating.
I don't think you read anything I submitted. If you had at least read the model of my machine, you'd realize I don't have any buttons on my dishwasher other than start/stop and on/off -- all other settings are dial settings. Plus, I don't have any type of display where numbers can be displayed. I can't perform the test you suggest so am still without any options. Are you able to offer something that pertains to my situation or do you simply see that I have a Bosch and offer some textbook response? I do appreciate your time but you are wasting mine.
