Range, Refrigeration and washer Fault Codes are very much used these days on the newer Electonic Controls.

This guide may be incomplete as manufactures use different parts on different models. This is a general guide to fault codes. We assume no responsibility for any action taken on your part as a result of using this guide. Consult your owners manual, as it may give the fault codes for your particular model. Contact a local servicer for repairs.

If you didn't find your model/ brand in these fault code charts Contact us! Maybe we can help find your code.

Bosch dishwasher test programs

SHI/U 43 MODELS

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 150?F) 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.

SHU 4322 & 4326 MODELS

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 150?F) 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.
