Question about Bosch 24 in. SHU6802UC / SHU6806UC Built-in Dishwasher

5 Answers

Long cycle and other probs.

Unit is 4 yrs. old and has always displayed "98" when we set it on regular wash. Now it displays "2h" and nothing has changed with my hot water supply. It also has a tendency to run for a long time when the display reads "1". It was doing this last nite again, running for about 15 minutes while the display read "1". I opened it and the water was still sudsy, so it looked like it had run for over two hours and never drained?? I canceled the cycle and ran the "rinse and hold" about three times to finish the dishes and get all the soap out. Also note that I used the same soap I always have used, and the same quantity. Any ideas?? Thanks

    Right on Rotu. It was a burn't solder joint. I soldered it and we'll see if that works. If not, I'll buy a new board. Thanks a Mill!

    my Bosch shv6800 dw suddenly is displaying 173 minutes for a regular cycle. Hot water supply and soap have not changed. It used to take about 75 minutes. Any easy solutions??

    Same issue - just started experiencing a wash cycle problem where it runs down to "1", the continued for what seems like an eternity. I am guessing that I need to replace the control board as others have indicated. Seems like this would be cheaper to do on my own than have a repairman take care of. It is a Bosch dishwasher. Any feedback as to where is a great place to order part?

This is almost always a bad control board. If you want to verify this, turn power off to the unit and remove the outer door by removing the 4 or 6 torx screws down each side and then remove the upper housinb by removing the remaining torx screws. Once you have the upper housing off, find the control board. It is a white box with lots of wires connecting to it. Lable the wires and take them off, then pop the control board out of place (it just snaps in) Once you hve the control board in hand open the white houseing into 2 halfs (it is hinged) and pop the board out of its holder (the half of the board without the buttons) and look on the back for a burned solder joint. Ths is how they all fail. You may be able to clean the joint and re-solder it, but I have never tried. If you Don't want to go through all that, just get a control board 99.9% surethat's where your problem is. Good Luck!

Unreal, just picked up a SHU6802UC off the Craigslist Free section, the guy just bought a new one because this one "Quit heating the water, and that screwed all the cycles up." Found this, pulled the board out, big burn mark right in the middle of the larger board. Perfect! Thanks!

Same problem. It was the solder joint on the board like described above. Diswasher is runs great again.

    How in the world do you guys get the upper unit back on once the control board has been replaced? I can't seem to get it back on at all because I can't seem to get it over the prongs they sit on!

  • fbhome4rent Nov 03, 2010

    Ended up practically taking off the entire front of the door. Only left the bottom TORX screws on either side so I could bend the door forward and get the top part back on. Fit like a glove.

Unbeliveable! This totally worked! Thanks for saving us $598 for a new washer.

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.

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 :)

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 dishwasher not draining is most probably faulty drain pump or drain hose is got bit loose.It has to be checked and confirmed

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.

Prolonged washer cycle time


Hi! I'm not familiar with this model, but it sounds to me like there is not a problem! If you set the delay time to 0H, switch off the unit at the main switch, then switch back on. If there is still a 2H displayed, it means that the PROGRAM that you have selected will take 2hours! This is fairly common for the Bosch units on the 50 - 65degC cycles...some models have a "reduced washing time" button - it looks similar to the "delay" symbol, but once pressed, it reduces the washing time by almost half (cuts on rinse cycles) If your model does not have a reduced time button, select a shorter cycle (35/40/50eco), and see if the time is less. Remember that the latest dishwashers are engineered to be more energy efficient and water wise, so they had to lengthen the wash cycles in order to get good wash results! Hope this helps! C.
