An "F" has appeared on the alphanumeric display
I turned on the dishwasher (Gaggenau Model GI936-760, purchased in 2002) as usual. Two hours later I noticed that the motor was still running. When I opened it I found that the alphanumeric display showed "F" (this "F" is not mentioned anywhere in the manual) and the soap dispenser hadn't opened. The dishes were dry - no water had entered the dishwasher - and dirty.
What's happened? How do I fix it?

The F must be followed by a number. F alone it is not an error code, but it looks rather like the symptom of a faulty timer control board.
Try first tripping the circuit breaker or disconnecting power cord for five minutes ande see if this can reset the error.
If it does not , then it is probably a defective timer board. In that case call Gaggenau at the number listed on the user manual, they will ensure that there is a fault and provide you with the replacement part.

Above is the service manual, this is what us engineers use, to service and repair.
It maybe that something has tangled up in the timing department. Please use the manual to isolate your problem with the troubleshooting guide.
Now tgis below, may or May not apply to your situation, however it is amazing the machines that respond to this "Fix" so it may well be worth a try, to start. Also. First.try simply unplugging from the Wall and leaving disconnected for 5 mins or so, plug it back in, often this clears any fault. Otherwise you will need to troubleshoot, or call a professional. Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.
