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

Same problem, dishwasher didn't seem to complete cycle to dry dishs.
Solder joint in the center of the board was black. I cleaned the connection and added new solder and it is working agina! Saved $150 for a replacement module.

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!

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

Tips for a great answer:
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 [email protected] 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.
