boiler keeps cutting out ?????????????

john0612

ever since we came back from holiday last week , our boiler and water were switched off btw, it keeps cutting out when i put it on.

we have no hot water now unless the heating is on, but it's clicks on for a few seconds then cuts out. The boiler is working because it is warm to touch , but it doesn't heat the rads and water now.

it sometimes works but i can't leave the heating on all day and night in this heat.

it's potterton netaheat and it's been in here since we've been here (5yrs) and probably a while before that.

Possible lack of water pressure in the system? I'm no expert, but I remember having a similar issue when the water pressure fell below 1 Bar - easy enough to remedy, in the boiler you should see the pressure gauge and somewhere nearby should be a small screw that can be opened up to allow more water into the system - close the screw when the pressure reaches the system optimum.

A manual for your specific model should be here: http://www.gotoplumbing.co.uk/findamanual_results.asp?pageSize=25&accid=993&sortby=&catid=3146&pg=4

I am far from an expert but have chosen in the last 3 months to do a bit of fault finding on my boiler.

I had the same problem, albeit with an oil boiler. First I thought of the water pressure but this did not cure the fault.
I then paid attention to what is called, I think, a Thermoswitch which on my boiler rests on the back of the control box/panel.
It is basically a little pop out switch which I understand pops out to stop the boiler firing when it believes the right temperature is reached.
Because the temperature had not been reached then I simply pressed the button in to reignite it until satisfied.

I will say that I only trust doing what I do whilst I require only a 10 minute burst to get hot water. I would not do it in the winter where I will require the boiler to be on for much of the day.

Also, I believe that the fault itself is indicating that I may have a faulty thermostat giving dodgy temperature readings.

Finally, I will say the problem appears to have remedied itself over the last couple of weeks.

Good luck.

I've just had the same thing on my boiler and mines now knackered at first I thought it was the pressure - added more water to the system and took the pressure up to 2.... still no joy! If I put hot water on, the boiler would just make loads of clicking sounds and flash like a Christmas Tree.
The plumber says it's the PC board inside the boiler that's gone on mine so I'm going to get a new one, which one, I don't know lol

It sounds like you need to calla plumber. Mine didn't charge me anything to have a look which was decent of him Good luck.

If the boiler is firing and going out a couple of minutes later you should check your pump, if the heat cant get away the boiler will shut itself down.
