Hi
A problem has recently started on my Main Combi 30 Eco elite. When the CH is set to off on the timer the upstairs radiators are getting hot. This seems to get worse when the hot water is running for a while. I have noticed that even when the CH is off and no hot water is being used the boiler fires up for a 1-2 minutes every 5-10mins with the hot water indicator flashing (CH indicator does not light)The system is not loosing pressure and there is no room thermostat (only radiator thermostats). If I switch the selector from HW and CH to HW only the problem seems to stop.
Does anyone know what this may be? Am I right in thinking this could be a diverter valve problem?
Thanks in advance
Matt
