Hello, The other week was below freezing weather, so I put the heating on my combi boiler.
The timer was set to come on 15min per hour overnight.
In the morning, I went into the kitchen to find the boiler was dead, about 3 to 5 litres of water on the floor beneath the boiler and the kitchen mains circuit was tripped.
Engineer came out and opened front cover and more water poured onto the floor (imagine a goldfish floating out, etc!)
The upper and lower sections of the boiler are divided by a metal tray (full of water). Above the tray the main parts are only the main heat exchanger, the fan and an expansion vessel. The rest of gubbins are below the tray.
After the boiler was dried out, he put it back together and it has been working OK. He is due to return to check it is still ok.
His theory is that something above the tray got blocked and some part that is normally water tight gave way under pressure and flooded the boiler, only to reseal itself.
The window was open over night and the radiatior was off, so the room got cold but I'd be surprised if it was cold enough to freeze the boiler (as it was on once an hour).
Has anyone seen this happen before or know the likely cause?
I'm just worried it could happen again as the cause has not been confirmed and would like to suggest any answer here when he comes back to check it over again.
Boiler is Baxi platinum combi HE
Thanks
