Re: Bosch SGS 5342 won’t heat up
The instantaneous water heater assembly comes complete with thermostat and turbidary sensors in place. Assuming that unit has been replaced the programme module is the device providing power to it.

Services?….not sure if you have had this module serviced but on that assumption I guess the only reason your machine is not heating is purely due to lack of water flow from the circulating pump?
The water heater unit has a water flow safety switch and unless sufficient water flows through the unit to operate that switch, it will not heat ❗
