Worcester Bosch 24Ri -Relay clicking?

I have managed to solve my problem by fitting a 470nF 500V AC Capacitor (Maplin part RG25C) across the Orange and Blue wires from the V4073 Mid Point Valve.

Hope this helps

Sounds like the same problem I have.

This seems to only happen when the Central Heating switches off, either with the Hot Water or on it's own.

I am slowly checking out the circuit but there seems to be a stary 50V floating around from some where which all seem to be pointing to the boiler

started happening on mine as well 2 years old.
when the boiler shuts down and overrun fan kicks in it clicks untill i reset the boiler or it cools down.
i did jumpthe main central heating pump to run when it was clicking and it stopped after 15/20 seconds.
