Bosch dishwasher SHU3032UC/U12: Gets
Welcome to FixYa.
Based on you description of the timer not advancing you`re on the right track when you said "Thought it might be the timer (control unit), but now am wondering if it could be the heating element or thermostat"
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.
The SHU 30** series Bosch dishwashers 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/ appliance technician.
**Turn off the breaker at the service panel before attempting any service suggested **
- 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 )
- 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.
**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.
