Fridgidaire/Electrolux dishwasher stuck knob

SOURCE: Dishwasher wont finish cycle

I have experienced this problem before and it turned out to be the main control board in the console. Not a cheap fix, either. The control boards are not serviceable, and can run over $100. Sorry, I hope I was of some help.

Try "resetting" the control board by running the diagnostic cycle. The cycle completes in 15 minutes. 
The details are in the service manual. The manual can be found hidden behind the tow plate (at the very bottom front of the washer).
The diagnostic cycle may tell you the problem. It also helps clear up some of the software gltiches. 
It is easy to run the diagnostic cycle.
Just the buttons in the following sequence. The sequence should be complete within 6 sec. 
heated dry -> Normal -> heated dry -> Normal
This will trigger diagnostic cycle of 19 intervals. Pay special attention to the intervals 18, 17, 9, 6, 4.
Interval 18 - displays your controller module number (should be letter 'd' followed by number 0 or 1 or 2 or something. Note that down for future reference.
Interval 17 displays 'software generation number' Note that down for future reference.
Then wait until you reach interval 9.  --- clean LED turns on - then an open or shorted thermister is detected.
-- Sanitized LED turns on - then the washer detected greater than 100 deg F temperature
Interval 7
-- Soaking/sensing LED should NOT come on (unless food soil is present).
Interval 4 -- Soaking/sensing LED should come on


Let the cycle complete and then try running the normal wash. Hopefully the possible glitches are cleared by now and you should have no problem. 
If this doesn't work, time to call the expert tech.

Try this link, http://www.applianceaid.com/boschDW.html for procedures for running self-tests on various Bosch models using the front door switches. Find your model and read and follow the procedure.
This remaining at '1' problem invariably relates to a 'heater fault' which has usually been traced to an open solder joint on the control board located behind the switches/indicator lights on front door. See pic here of open solder joint http://www.flickr.com/photos/zenzoidman/145089572/ In most cases, the heating element has not been at fault.
I got mine going again by resoldering the joint and saved ~$300 in parts & labour. If this is beyond your skill set, then replace the control board assembly, 266746, which is used on multiple Bosch models. See this page for more information if you want to try to DIY. http://www.appliancejournal.com/appliance-parts/bosch-appliance-parts/bosch-dishwasher-control-module-266746-37/

If this is still beyond your skill set, then call a tech & supply the Bosch model, serial number, and the results of the self-tests.

I believe you may be over sudsing, Try a few cycles with vinegar and no soap. Do not use dishwashing soap at any time ever. See if the vinegar trick helps...helijm

Remove the toe kick by loosening 2 screws. There is a panel there with little lights that correspond to specific problems. The light that is on will correspond to the problem that the dishwasher has detected. Correct the problem and you should be good to go. I have no idea why this is not in the instruction manual. A common one is that there us a leak that the dishwasher has detected, normally in the drain pipe.
