My Bosch dishwasher won't shut off. The timer says "1" forever and when you open it there is about an inch of SOAPY water still there.If you press start it goes to "13" and again counts down to "1" and stays there.

1. Defective cycle timer
2. Defective door interlock wiring or latch

Hi Mike Heneghan - The issue may lie with the door latch; a door switch is used to start and stop your dishwasher. It's a safety feature that won't allow water to flow with the door open. With a faulty door switch, there is a chance your dishwasher won't start at all. Dishwasher door switches are about an inch long. They are usually black but can be red. There are metal prongs on the body of the switch called terminals. Some door switches have two terminals and some have three. If your door switch is OK, check the timer assembly. This controls when and how long power is sent to other controls on your dishwasher. If these controls don't receive power, they won't work. The timer assembly contains a motor. Check this motor as well. It is often cheaper just to replace the timer motor rather than the complete assembly. My last suggestion is to check the cycle selector switches. These switches indicate cycles for washing, drying, and setting the temperature of the water. If one of your switches is the problem your dishwasher may not start. Dishwasher cycle selector switches tell the timer which cycle to run by opening and closing electrical circuits. Most selector switches are six to eight inches long. They are usually black and have terminals. By testing each one of these parts with an ohmmeter you should be able to determine why your dishwasher is not working. It is possible for other parts to fail but these are the most common parts to check. If any proves to be ineffective, I strongly suggest contacting a professional to move forward accurately.

Timer control needs to be replaced.

1) the water can be pre-heated, if this is your case, you must test the heating element +thermostat see the video how to test it. 2) test the timer is stuck with some conctacts, try to clean, tight any wires loose, open, or broken, or replace the timer. God bless you

Proceed with this step:
Timer
check the timer, and the linkage see it is defective.
Bi-metal switch or wax motor
test the swithc or the motor for defective.
Detergent cup, itself
can be clogged, for to open.

sincerely. God bless you.

Hello, This sounds like a very common problem with Bosch dishwashers unfortunately, that is based on your description it likely has a faulty heater relay. The "1" is actually an error code identifying a heating fault. The issue with Bosch dishwasher`s most times lye`s within`the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this error code "1", but not very probable ). I`d first suggest calling in an authorized bosch servicer, however If you feel capable there`s a way to visually inspect the control. It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit sit`s and takes forever top finish ( because it can`t heat to advance or until canceled ) trying to heat the water. **Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)** **Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.** Hope this answer`s your question, let me know if I can assist you further. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution and leave a testimony. Good luck. macmarkus :)

This is too common a problem with these units. I have written a guide to help folks out with it. Find it here.

I saw my repair man do the following, which you might try...
Open the door and simultaneously press & hold down the power button with the 2 buttons used on your model to "Cancel & Drain." If the unit comes on it now is in self-diagnosis mode. Release the buttons and close the door. The unit should start to fill with water. Press the power button to exit the mode.

There is a heating element in the dishwasher that heats the water to about 155F at which point a thermostat closes and sends power to the timer to advance. If the water does not reach this temp, the dishwasher will not advance. Often the problem lies in a faulty part in the heating circuit like the heating element or the thermostat faulty but you will need a technician to verify.

Disassembled solenoid, found plugged inline strainer (caused by water shut-down in building to replace recirc. pump) Pulled and flushed filter basket, problem solved. Solenoid must be removed to access filter which is in sol. body. I hope this can help anyone who does'nt have a tech manual or flow diagram.
