Vokera leak

[redkite58]

Old vokera linear 28 water leaking from front of boiler behind the front panel you can open. It seems to be coming from a black thing sorry that what I can describe photo attached. Any ideas and potential repair costs, thank you so much I have turned it off at the electric but its still leaking.

Looks like the diverter valve cartridge behind the actuator but picture is not great. Not expensive and possibly best to replace both cartridge and acuator, any local installer can do this. Vokera will do this for you for a fixed price but a local guy might be cheaper.
