Question about Bosch 24 in. SHU43 Built-in Dishwasher

2 Answers

I have an SHU 4322. It displays "2H" in the countdown window. It will drain-cancel properly, but all of the programs display "2H" instead of the normal # of minutes for each cycle. How do I get the wash cycle to start normally?

    Kevin,

    Does this mean I need to replace the control module? If so, what part do I order--it appears to #481035 for $106.50, but I'm not sure? And, where would you recommend I order it from? Is Bosch the best/only place to get it from?

Just reset the unit by unplugging the cord from the wall for 4 hours. The purposed for this is to drained the current stored in memory IC . So it will works normal again. Plug it again after 4 hours to see the result..

Good luck:

It is a design flaw in the control unit. There is likely a burnt pad on the circuit board. Bosch claims it is not a flaw, but will offer a 25% discount on the control unit if you complain load enough.

I have a SHU5305us/u12 and my front door lettering got erase. anyone have a picture or a manual that tells me what each button means.


Cycle Interruption

As a safety feature the dishwasher will automatically turn itself off whenever the door is opened. However, if the door is opened quickly while in a wash or rinse cycle some water may splash out of the dishwasher. For this reason it is recommended that the machine always be switched off before opening the door.



To Interrupt a Cycle

1. Press the on/off button to stop operation.

2. Wait at least 10 seconds (or until the water noises stop) before opening the door.



To Resume a Cycle

1. SHU/SHI models, close the door and press the on/off button.

2. SHV models, push the on/off button and close the door.



Changing a Cycle

For Bosch dishwasher models SHI 6800 and 4320, SHU 5300, 5310 and 6800 press the program button of the desired cycle TWICE. For all other Bosch dishwasher models, press the program button of the desired cycle ONCE. The chosen cycle button (or the light above it) becomes illuminated, showing that it has been selected.

* SHU 3030 and SHU 3130 models do not have program lights.



Cancelling a Cycle

Each control panel shows which buttons to simultaneously push to cancel a cycle. Refer to your dishwasher to find the cancel drain buttons on your particular model.



1. Press the indicated buttons at the same time and hold for approximately 3 seconds.

2. When the drain pump noises stop and the LED display or clean light indicate that the end of the cycle has been reached, the dish

washer is reset.

3. Press the on/off button to turn the dishwasher off.

4. The dishwasher is now ready to run a selected cycle. Add more detergent if necessary.

My gaggenau dishwasher GM 954-110 is not working. when i switch it on the display panel shows 2H.


Hello, welcome to FixYa.

The dishwasher you're speaking of (provided it is indeed a Gaggenau GM954) is built by Bosch as you may or may not know.

To address your concern regarding the 2H in the display actually needs to be done in two parts. I'll start with the basic info associated with the 2H displayed.

This can be simply indicating the previous cycle exceeded a 2 hour wash cycle, not necessarily an error and can be attributed with too cold water entering the dishwasher (below the recommended 120F), a longer than normal drain time (due to partial blockages, kink etc. hence longer time needed to complete the cycle) or inproper water circulation during the cycle.

Aside from these issues, it (2H) can also mean the unit has a heating error and if left long enough will show another error of "1" in the display, extremely long wash times, etc.

**The first thing I'd suggest before attempting any repair is running an additional cycle while making sure the water inlet is hot (120F optimum) and the unit does indeed drain fine.

**A fair indication of proper draining is to start a cycle and once washing begins (2-3 minutes) activate the "cancel" and the unit should adequately drain in the 2 minute time allowance.

**To identify proper water circulation, place an empty cup in the upright position in the top rack, start a cycle and inspect the cup after 2-3 minutes and it should be full of water.

After trying and posting the results of these thing's we can move forward with potential heating errors, the cause, and how to remedy them. Let me know what you find and I'll continue to assist you in any manner possible going forward. Good luck.

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 :)

Water won't drain


Do the diagnostic test:
SHU 53 MODELS

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
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.

The "2H" is an error code indicating the control panel needs to be replaced.

May 08, 2009 | Bosch 24 in. SHU53 Built-in Dishwasher

1 Answer

What does the 2H mean? It seems to be the "standard" but the manual has no definition.


Great question!
2H means 2 hours -- 120 minutes ... the display only has 2 digits so it can not display 120 minutes. When the timer gets done near an hour an one half, it will start to display a countdown somewhere near 90 (minutes)
Yes, the cycles are long on the LG LDFxxxx dishwashers, just like all water and energy conserving dishwashers.
This really is a good dishwasher, recommend you keep the rinse aid dispenser filled up and ALWAYS use a brand name powder (like Electrosol or Cascade.) Also make sure when it was installed, it was properly leveled.
Hope this helps!

Error code 2H


The control panel needs to be replaced (indicated by the "2H" error code displayed at the start of the cycle).
BTW - The number 1 displayed at the end of the cycle indicates the cycle has timed out (i.e., it doesn't mean 1 minute remaining). Hence the continued running of the unit. Until you replace the control panel, you'll have to manually cancel the cycle at this point.
