Question about Bosch 24 in. SHU43 Built-in Dishwasher
There are no adjustments for cycle timing. What does affect timing is temperature of the water coming into the DW. The hotter your supply water, the shorter the time to cycle, BUT if your water is too hot, the cycle time may become too short to light the NSF 'Sanitize' indicator. But since the cycle is taking so long, this is an indication that the DW's water heater is not heating the water hot enough to advance the countdown timer in a timely manner. The control logic is waiting for the temp to come up to an appropriate level to ensure adequate washing, rinsing or drying times. Likely your display is showing '1' for a long time as a symptom of this problem, as well.
This link http://www.applianceaid.com/boschDW.html has procedures to run self-tests on various Bosch models. I suspect that you can confirm a 'heater fault' on your unit by running the self-test.
This 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. If you have a Torx driver, soldering iron & bit of solder, you can effect a repair yourself in about an hour. Otherwise, a replacement control board is required.
- If you'd like to attempt replacing the control board yourself, refer to this link for part & DIY information. http://www.appliancejournal.com/appliance-parts/bosch-appliance-parts/bosch-dishwasher-control-module-266746-37/
- Else, place a service call to the tech of your choice.
