Afternoon all
Customers Bosch dishwasher SMS63M42GB/B1 is displaying E19 , elsewhere stated that it could be the valve at the side tank (heat exchanger)?
tried doing a reset but the fault code E19 wont clear .
anyone else had an E19 fault ?
Check the resistance of the coil on the heat exchanger (Front Left at the bottom) – I have only seen one of this error code and on mine it was open circuit, the error automatically corrected itself after I replaced it.
