Anyone had this on a Vaillant Ecotec?
Hot water works fine, heating randomly works.
No fault codes, works in service mode.
When heating is called for the radiator symbol will show on the display pump runs then nothing happens. Eventaully it will kick in.
As its not showing a fault I can only assume its the pcb
