Vaillant Combi boiler

On a call out this morning to check a vaillant Combi boiler that has been dripping water from underneath.

On opening and checking boiler, I can clearly see this diverter valve spindle slowly dripping.

When this happens, boiler will loose pressure and flash error code , could be flashing F75.

Solution is to replace this diverter valve ASAP, because introducing fresh water into your system everyday is really not good for your heating system.
