Hi
Wondering if anyone could point me in the right direction please.
We have an old traditional old Potterton E50 boiler with an old Honeywell time switch and a more recent Salus wireless thermostat.
I have completely powered down and re-set the Honeywell and Salus a couple of times and installed new batteries in the Salus.
Mist of the time everything works fine. The boiler was serviced professionally last November.
Occasionally though, and most often in the afternoon for some reason, the Salus clicks in, we get the green light on the receiver but the boiler doesn’t fire up. At this time of day the water is off.
As soon as we boost the water the boiler fires up and the diverter moves to the middle. If we immediately switch the water off again the boiler stops but if we leave heat and water on for 10 minutes and then switch the water off, the boiler stays on, the diverter moves to H and we have heat.
The diverter seems to be doing everything it should, moving from water to heat to both.
It only happens when the water is switched off, but it’s intermittent. It happens once or twice a day and is getting no better but no worse.
Any suggestions as to the next step in our investigations would be appreciated. It’s going to be hard to demonstrate the fault if we call in a plumber because the chances of replicating the issue are pretty remote.
Thanks all.
