Because the timer controls many operations, a faulty timer can cause many problems. The timer is a complex component, so you shouldn't attempt a do-it-yourself repair. Test the timer with a VOM set to the RX1 scale. To gain access to the timer, remove the front control panel. The timer is directly behind the main timer control knob. Disconnect one of the timer's terminal wires and clip one probe of the VOM to each terminal. If the meter reads zero, the timer is working. If the meter reads higher than zero, the timer is faulty and should be replaced.

The timer is connected to several wires that supply power to operate the various functions of the dishwasher. To replace the timer, have a helper hold the new timer next to the old one. Connect the wires of the new timer one by one, removing the old wire and connecting the new, to make sure you connect the wires correctly. The wires may be friction-fit on the terminals. If they are, use long-nosed pliers to remove the wires. Don't pull up on the wires, or you may break the connection between the wires and the clips. After connecting the wires, set the new timer in position, secure it the way the old one was secured, and replace the control panel and knobs.
If your dishwasher won't fill with water properly or isn't drying the dishes, you most likely have a valve or heating element problem. In the next section, we'll discuss how you can assess these types of problems.

Try unplugging power cord for fifteen minutes first, see if this clears the error.

    Try first unplugging power cord for fifteen minutes or so, this will drain power from control panel, reset the eeproms, and can fix some problem on the controls circuits.
    Switching off it is not the same, you need to unplug the cord.

    If you still get the message, check the water supply at the back, check that water is coming throught,
    check also that the drain hose at tle lower side of the appliance is not stuck or obstructed.

    If you do not find anything wrong, then there is a faulty part, maybe the control , the heater, the pump or one of the sensors.

    Folow instructions here if you want to diagnose the problem further.


    If you need to call a technician you can use the number listed in the final part of the owner manual.

I have a Bosch dishwasher model # shx4ap05uc/06 and I want to silence the alarm for when it is done. It goes off every 10 minutes until you open the door


Hi,

Yes, you can switch the cycle completion signal off (or raise/lower the volume)

1. Switch the dishwasher off using the ON/OFF button
2. Open the door
3. Switch the dishwasher on again. (One of the wash cycle LEDs will flash.)
4. Hold the > button in. Continue holding it and press and release the Start/Reset button once, then release the > button.

"Clean" and one other LED should now be flashing. This indicates that the dishwasher is in the options/settings mode. If they are not flashing, start over at step 1.

5. Press > repeatedly, until the LEDs for "Clean", "Sanitized" and "Rinse Agent" are all flashing.
6. Press repeatedly until none of the LEDs are flashing.

The number of flashing LEDs indicate the volume setting . . .

0 = Silent
1 = Volume level 1
2 = Volume level 2
3 = Volume level 3

7. Press the Start/Reset button once to save the setting and exit the options mode
8. Close the door
9. Switch the dishwasher off.

Hope this helps. Please let me know if you need further assistance.

Regards,
BElectric

Have a shu 4322 dishwasher it fills with water and drains but the spray arms do not spray. have not tried anything yet.this dishwasher is not hooked up. it was given to me by a friend who replaced all his...


Hello,

Welcome to FixYa.


There was indeed a recall involving the control replacement nearly two years ago now if I recall.

As for checking into the present issue ( it doesn`t sound like anything to do with the control based on your description ) it sounds like the pump impeller may have become stuck. Did the dishwasher sit idle or in storage unused for a period of time ?

I have a service bulletin I could send you via email regarding remedying that issue of stuck impeller if you contact me at macmarkus@live.ca

I`d suggest you run the dishwasher through a diagnostic, but either procedure will require hooking it up.

To do this test/diagnostic on the SHU4322 series machine, it is as follows...

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)

0 = No faults detected
1 = Aqua Sensor ("Sensotronic") fault
2 = Heating fault
4 = Filling fault
8 = NTC (temperature sensor) 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.

i.e.

86c0a8d.jpg

If water level switch 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 has failed (opened), display will show "0", water won't heat (to 150?F) and water won't stop circulating. If NTC probe has failed (opened), display will show fault code "8" immediately and testing will end shortly after water has started circulating.


What needs to be done to solve the problem will depend on the results/findings of the dianostic, so let me know what you find and we can go from there.

Either way keep me in the loop and I`ll assist you the best I can. Thank you for choosing FixYa and good luck.

Regards,

Macmarkus :)

Controller, door interlock and motor replaced. Unit comes on, but does not operate.



Hello Dave,

Welcome to FixYa.

Try this test I posted below and let me know what error you find...if any.

To begin the test program, press both the SCRUB WASH and DELICATE/ECONO wash program buttons at the same time

as you turn the unit on by pressing the ON/OFF button. Initially, the control unit version number will appear in the display

(e.g./ 20 = version 20, 21 = version 21, etc.).


When the wash program buttons are released, the LED's above them will begin flashing. To end the test program or test cycle, press the ON/OFF button.


To check the wash program LED, press its corresponding button.


To check the Cycle Countdown display, Refill Rinse Agent LED and REGULAR WASH button LED, press the REGULAR WASH button (press the DELAY START button to test the

Cycle Countdown display alone).


The Cycle Countdown display should show "88" when the DELAY START button is pressed and "8h" when the REGULAR WASH button is pressed.


To start the test cycle, press both the SCRUB WASH and DELICATE/ECONO buttons a second time.


When the test cycle has completed, the Cycle Countdown display will indicate a fault using the codes below. If a combination of faults exists, the code numbers will be added together, (e.g./ 6 = faults 2 + 4).


0 = No faults

1 = Aqua Sensor ("Sensotronic") fault

2 = Heating fault

4 = Filling fault
8 = NTC (temperature sensor) fault

email me at macmarkus@live.ca and I can send you via a "pdf" of the diagnostic/repair manual for your specific Bosch...provided it is indeed a SHU5316 unit.

I`ll watch for your reply. Good luck.

Regards,

Macmarkus :)

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.
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

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.

Dish washer does not turn on CL light stays on when reset count down 6 appears then goes to CL


Hello and welcome to Fixya,

I have a ton of service info on Bosch so it`s best I post you an exert from the service pdf`s I have on my PC which will explain the meaning of "CL" and then go from there. This is not a common indication of a control problem, but it could be a problem with the plastic casing which houses the control, we`ll deal with that later.

I`ve underlined the section pertaining to the "CL", this is for the SHU68** dishwashers only.

TO OPERATE:

First depress the On/Off Button until it locks in place.

Once the On/Off Button is depressed the LED above the previously used cycle will illuminate.

To change the cycle, simply press the desired Cycle Button twice. The LED above that cycle will then illuminate.

The Cycle Countdown will display an approximate run time for the cycle chosen.

This run time will depend on incoming water temperature and the turbidity of the pre-wash water.

Note: It is normal for the Countdown Display to remain at a time increment for more than one minute, or skip a time increment depending on the calculations of the Control Unit. Also, with continued use the Control Unit will learn the wash and temperature patterns for the most commonly used programs and will then reduce the overall start and running times.

At the end of the cycle the display will show a CL, indicating that the cycle is complete.

**TO CANCEL A CYCLE:
Press the Scrub Wash and Delicate / Econo Buttons both in at the same time. The unit will then drain and the figure CL will appear in the display.**

DELAY START:
The Delay Start feature allows the unit to be delayed for up to nine hours. To program, start the unit as described above, but after selecting a cycle push the Delay Start button. The display will show a 1h, or one-hour delay. Continue to depress the Delay Start Button until the desired delay time is reached (up to nine hours, 9h).
The unit will begin automatically once the delay time has elapsed. To reset the delay, press the Delay Start Button until it reaches 0h.

TOP RACK ONLY:
The Top Rack Only feature can be used in conjunction with any cycle. To active, press the Top Rack Only Button after selecting a
cycle, the Top Rack Only LED will illuminate and all water will be diverted to the upper wash arm for the complete cycle.

REFILL RINSE AGENT LED:
The Refill Rinse Agent LED is activated via a Reed Switch on the Detergent Dispenser, Section 4, Fig. 8-3. The LED will
illuminate when the Rinse Agent Dispenser is empty.
Service note: The Refill Rinse Agent LED will also illuminate when the dishwasher door is opened and then
closed even if the Dispenser is full, but will only remain lit for a few seconds.

“F” CODE:
An “F” in the display window indicates a filling fault.

Please note: If the door is opened during the cycle, the On/Off Button will be reset to off and must be depressed again to re-active the cycle. The cycle will resume from where it left off.

Now that you are equipped with this info, what I`d suggest is trying the **cancel option. ( ** see above )

Once you`ve tried the cancel option, select a Regular Wash and post back what happens and I`ll try to assist you from there.

Good luck.

Start flashes and will not begin wash cycle


My dishwasher Model is 665 15891790 and the serie #FG3907905. After programing my dishwasher and pressing the start button, it fills with water, but when it is due to start the sensing light comes on. I have notice that the ring under the watering arm on the bottom of the machine seams to be cracked. Could that be the problem for the machine not starting its' cycle. Thank you.
