Dial Timer sticks between wash or rinse modes

For Bosch Dishwasher Ascenta models, open the door to reset it. Hold the Start-Reset button for about 5 seconds or until the Active indicator turns off. Shut the door of the dishwasher to allow it to thoroughly drain before turning it off.
This should reset the cycle drain.

Hello,

Welcome to FixYa.

Based on your description " Will remain stuck in wash cycle and continue to run. If moved on to rinse cycle it will again stick and not advance."

I suspect the thermostat isn't satisfied when heating the water, hence it get`s hung up trying to heat in the part`s of the cycle it`s called for.

It very well could be caused by a faulty flow switch, NTC or heater as well but not very likely.

I'm basing this on the most common issues and it is a generalization, but if you provide a model number I can speak directly about your machine.

Model and serial are attached to the right hand side of the door,

i.e.




The dishwashers made by Bosch with a rotary dial timer have very few if any, issues with the actual timer or element but they do with the thermostat within the door panel.

If it ( the thermostat ) is not satisfied the water may heat but not be indicated via the thermostat, hence timer will not advance.

Here`s what you can try. If you have any hesitation or reluctance to service this yourself please call in an authorized B/S/H/ ( Bosch/Thermador/Gaggenau ) appliance technician.

**Turn off the breaker at the service panel before attempting any service suggested **

1. You will require a #20 torx screwdriver to remove the door panel by taking out the screws around the panel, except the ones along the top ( watch the edges they are very sharp )
   
   
2. Once the panel is removed you should see the thermostat over by the detergent dispenser clipped to the inner door, remove it and test it. You`ll need a ohm meter/multi-meter plus a lighter or match to heat it up to see if it open`s & closes.
   

Example...


**NOTE** it can occur the thermostat can become loose and detach from the bracket which holds it in place, this too can manifest in the sysmptom of the timer not advancing.

Let me know how you make out and what you find.

Thank you for choosing FixYa and Good luck.

I have a 10 year old Bosch SMU 7000 and the drying function has ceased. Dishes are wet after all cycles. From what Ive read this isn't worth fixing because Bosch are so difficult to get into.

Do you mean the timer or control dial sticks. If so then it may be the timer mechanism itself.

Make sure that when you are skipping a turn on the timer that the machine is actually performing that particular task of the cycle. For example if the timer gets stuck before the drain cycle, and you manually skip forward to it, that it actually drains the water out.

If so then it is most likely a worn timer mechanism which sticks.

If the cycle doesn't complete, check these:

Water-heating cycle
Timer
Water-heating cycle Many dishwashers heat the wash and/or rinse water to a higher temperature, as the cycle calls for it. In these cycles, the dishwasher pauses after it has filled with water, waiting for the water to reach the pre-set temperature. What happens next, depends, as follows:

• On some units, the pause is timed and the unit continues after the allotted time.
  
  
• On others, the cycle can't continue until the water reaches the higher temperature. If you have this type of dishwasher and the water isn't being heated (say, because of a problem with the heating element or thermostat), after the unit stops at the heating cycle, it never continues. When you repair the heating-system problem, the "cycle problem" is fixed too.
  
  

Timer Timers don't often fail. But if every other part of the dishwasher seems to be working properly and the timer knob seems to be stuck in one place--doing one function continuously--the timer may be at fault. Dishwasher timers can't be repaired. If yours is defective, replace it.

I have been told to replace the timer which I am looking to do the same to my machine!

Hi Russellpaola


it sounds like to me that the water valve is sticking open. you should have it replaced

plz let me know if this helped

Try using a quick cycle and see what happens. Don't use sanitize or any extra heat cycle. Sometimes during sanitize high temp rinse or other cycles the timer motor is stopped until the water heats up. The sensor could be defective. Not all machines do this and I'm not real familiar with your particular one.
