Arison Euro Combi A/23 MFFI type C boiler.
The heating is coming on on occasion although the system is set to hot water only (summer setting).

I have just checked the Manual and on PAge 22 under the list of Malfunctions it says if the radiators are heated in summer mode the 3-way valve is defective.

Hope this helps

I've had this same ongoing problem with my boiler since June, Engineers have come out and changed a number of parts only for other problems to arise. The engineers I called had no clue as to why it would come on by itself, a part which they said MAY cause this is the diverter valve. I've had this part changed but other problems have arised so we are not sure if it worked.

At the moment my boiler isn't working at all and Im waitng for an ARISTON engineer to come and have a look at it but my regular engineer is looking to get a new boile as almost every part has been renewed.
