Question about Bosch 24 in. SHU53 Built-in Dishwasher
Welcome to FixYa.
I just read your previous post and I wouldn`t replace that timer/control just yet. There is 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.
The culprit will 99% of the times be one of the pins from the heater relay,
**Flip this over and inspect the solder joints, it will be obvious when you see it.**
This ones new, but it's where to look...
...hence the unit doesn`t desolve the detergent properly or clean worth a darn because it can`t heat to the required 155° in wash to 160° in rinse
You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow switch indicates it has adequate water to engage the heater.
**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, 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 or turn off the breaker before attempting any service to the dishwasher.**
As you alluded to though, if you buy and replace the control It will resolve the issue as well.
Hope this helps before spending money perhaps not necessary.
Let me know if I can assist you further. Thank`s for visiting "FixYa" for your repair inquiries.

Thanks for using FixYa. If the cycle doesn't complete, then the first thing that should be checked is the Timer and then the heating element. 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. Please do accept the solution if the issue is resolved or post a comment for further assistance.
