No, this here is not how most dishwashers work!!
Comment: My Bosch dishwasher was having problems filling. No fill, and the drain motor would continuously run.
Help: After further investigating the problem, I noticed water in the base. I sponged out the water and the dishwasher reverted back to its normal working condition. I *think* the problem was a bad water fill value. After I removed the water from the base, I turned on the water and it would not stop running and flooded my kitchen.
Help2: Certainly *sounds* like the float is stuck in the over filled position or possible a bad float switch, if the float is stuck in the up or full position, the d/w will not fill with water and the drain motor will often run all the time.
Comment: This machine will not finish any cycle except rinse and hold. It generally counts down to 30-42 minutes on the regular cycle and will not advance anymore.
After running the test program for SHU 53 models as suggested, the display shows a 2 fault which I understand is a heating fault. What does this fault message mean and how do you deal with it.
Help: Many times the control board gets a burnt spot on it or the solder joint lets go and the heating up of the water quits so the d/w may not finish it's cycle or may take way too long to go through a cycle.
On the back side of the control board, the board may be damaged, example one and example two.
Did someone mention a test program?...yes they did...
To start test program, press and hold both POWER SCRUB PLUS and REGULAR WASH program buttons, then turn unit on by pressing ON/OFF button. When 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 start testing, press both POWER SCRUB PLUS and REGULAR WASH buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
WASH = Heater fault
RINSE/DRY = Water filling fault (over or under filling)
CLEAN = NTC (temperature sensor) fault – note circulation motor stops shortly after it started during an NTC fault
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), RINSE/DRY light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150ºF) and water won't stop circulating. If NTC probe (f2/f4) has failed (opened), CLEAN light will come on immediately and testing will end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.
To start test program, press and hold both REGULAR WASH and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. Initially, control module version # will be displayed (e.g./ "20" = version 0 without 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 REGULAR WASH and RINSE & HOLD 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.
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 # will 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.
