Hi
I have a Potterton Gold HE combi boiler. It has recently started to have a problem where the hot water will go cold after a few seconds of running. Some info which may be relevant:
Any ideas what might be the cause of this?
I have a Potterton Gold HE combi boiler. It has recently started to have a problem where the hot water will go cold after a few seconds of running. Some info which may be relevant:
- This happened suddenly, not gradually. One minute it was working, the next it was not.
- The fans/pumps or whatever makes the whooshing and whirring sounds in the boiler is still working while the hot tap is on (even after the water goes cold).
- The light on the boiler to indicate the water heating is active is on (even after the water goes cold).
- The digital display on the front of the boiler (which I assume shows temp) goes up to into the 90s just before the flame turns off. It then drops to 80 and the flame kicks back in. This cycle repeats, but the water never gets warm (though it is not ice cold like from the cold tap).
- The flow rate with the hot tap fully open is about 5.5 l/m.
- I have a closed central heating system (I think - there is no tank anywhere anyway).
- As far as I can tell the central heating is working - the radiator heats up.
Any ideas what might be the cause of this?
