I have the same boiler and the same problem. It's been diagnosed as a faulty diverter valve - its job is to switch between hot water to taps/other appliances (e.g w/machine) and hot water to radiators, very likely to be sticky valve.
If changing diverter valve its often wise to change the overheat thermostat at the same time as the two are quite difficult to diagnose seperately. Likely cost for both parts fully fitted is circa £400 (London).
I've given up completely as i've had repeated problems with the Europa. Every plumber that's looked at it shudders and says its cheap and nasty. New boiler for me.
