I have a problem with the DHW on my mini c28. I get CH and no Hot water but if I pull the black flowswitch, the red light comes on and it flips to hot water and no CH. When I push it back it reverts back.
I've replaced a burned out ignition PCB but still have this problem. Any advice would be much appreciated.
