Re: Bosch dishwasher sps2432au/03
The standard failure on these machines is the wiring loom breaking at the door pivot point.
The circulation motor uses a relay as it’s start device – that may have failed.
The heater has a diaphragm pressure switch fitted, so no circulation = no heat.
For parts and exploded diagrams, go to http://www.bshcustomerservice.com and follow the links into spare parts.
Not much chance of a wiring chart, I’m afraid.
