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.

This is the washing machine fault-code page. Note that these are not definitive lists, and manufacturers may change the codes without notice. This can be due to modifications, new on-board firmware, or later modified programmer boards during long manufacturing runs. Note also that some codes may cover more than one fault or major item in the machine. For this reason, the fault-codes quoted below should only be used as a guide to the problem area, not the actual failing part.

 

AEG: This set covers those machines with “SENSORLOGIC”, that is most LAVAMAT series machines. The codes appear as a binary code read using the upper 4 or lower 4 of the spin-speed indicator unless there is a digital display. NOTE: only codes F1 and F2 can be cleared by the user, other codes may need to be cleared by a procedure ONLY AFTER THE FAULT IS RECTIFIED. The procedure is: HOLD IN THE SHORT SPIN AND PRE-WASH BUTTONS, THEN TURN SELECTOR KNOB FROM OFF TO GENTLE SPIN (SOME MODELS USE PRE-WASH + SOAKING HELD IN, THEN TURN FROM OFF TO SHORT-SPIN. SEE BELOW.

F1: Single flashing LED (900 spin) or F1 (C1 on some models) in the display - this usually means that the electronics is not detecting a fast enough cold fill supply, or NO cold water coming in at all. Check that the cold valve has not been turned off accidentally. Then check that the supply is OK, and that the connection hose is not kinked or flattened. If not any of these, then the cold supply solenoid valve is faulty.

F2: Single flasing LED (1000 spin) or F2 in the display (C2 on some models) - this usually means that the machine is detecting that the water is not pumping out. This is often due to foreign objects finding their way into the pump and jamming it. Follow the “Cleaning the Drain Pump” section in your user guide, which should also refer you to the “emergency draining” procedure first. Note that this could also be a sock or similar blocking the lower (sump) pipe that leads to the pump. Follow the draining procedure and tilt the machine on its side (no more than 45 degrees) to get at and inspect the sump hose. If not that, then remove the pump and test it on a test bench, replace if faulty.

F3: Two flashing LED (900 and 1000 spin) or F3 in display (C3 on some models) -This is quoted as “Aqua-Control triggered”. I suspect this is an unexpected high water level condition, and could be a faulty or jammed pump (See F2 above), or a faulty float (level) switch.

F7: Three flashing LED (900, 1000 and 1200) or F7 in display (C7 on soem models) - Heating fault. Check heater element for continuity, if OK, check heater relay. Continuous water input though a faulty valve can also give this error.

F8: NTC (thermistor) temperature sensing device short or open circuit. This replaces the old-fashioned thermostat, and usually measures between 20,000 and 30,000 ohms cold. This could be a C8 in the display on some models 

F9: (C9 on some models) MOTOR FAULTS - the common cause of this is just worn out motor brushes. Be careful to get the serial number of the machine, and the part number and make of the motor, plus any numbers stamped on the brush-holders if you can, since there can be 3 or more different brush types in some machines of the same model number! The other causes of an F9 error are TACHOMETER short or open circuit, motor short or open circuit, or motor jammed. ALSO SEE C9 CODE: NOTE: the C9 on some AEG LAVAMAT models like the 71400, 72600,74620, 86720 and possibly others, is the same as the above F9, and is usually MOTOR BRUSHES WORN OUT. After replacement, you will need to clear the fault indication held in the PROGRAMMER PCB logic: With the Switch in the OFF position - Press and hold PRE-WASH and SOAKING buttons in at the same time, then turn the control knob to Short Spin. Wait one or two seconds and all the indicators should illuminate. Then turn the control knob to OFF. All the indicators should go out. Then try to use your machine as normal. This should clear the C9 error code. If it does NOT – there may be another fault present.

AEG: washer driers

E72: ON the L16830 model, this is the temperature sensor (NTC) faulty. With NTC faults, it is also worth checking the drum heating element. Kindly supplied by KM of London.

BOSCH EXXCEL MODELS

F16 Close the washing machine door properly; washing may be caught.

F17 Turn the tap on fully, check that the supply hose is not kinked/jammed; clean filter (see page10 of manual). Also check water pressure is not too low.

F18 Clean the detergent/solution pump (see page 10) or ,check that the outlet pipe/drainage hose is not blocked.

F21 Motor fault. Call customer service. (NOTE: if the motor brushes are worn, these can be replaced by a competent person).

F23 Water in the base pan, appliance leaking. NOTE: With power off, remove back panel and check for leaking hoses, or a leaking door gasket, with a good torch. Call customer service.
