Question about Bosch 23 in. SHU303 Built-in Dishwasher
welcome to FixYa.
Based on you description of the timer not advancing I initially suspect the thermostat isn't satisfied when heating the water. This could be caused by a faulty flow switch, NTC or heater as well but not likely.
The SHU 30** series Bosch dishwashers with a mechanical 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 **
**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.
