A boiler that fires, runs for a few minutes and then stops has usually decided something is unsafe and shut itself down on purpose. That is the safety system working. Resetting it over and over is asking it to ignore whatever it found, and on the older stock around Great Bridge the thing it has found is often a blocked condensate pipe or a system full of sludge.
What's involved

Boiler Keeps Cutting Out in Tipton, done properly

The code narrows it to a part

Modern boilers say what they saw. We read it off the display, confirm it on the boiler rather than off a forum, and work from there.

Frozen condensate, every cold snap

The white plastic pipe running outside is the first suspect from December onwards, and it is the cheapest fault on this list to put right and to insulate against next winter.

Circulation, not combustion

Sludge in the radiators makes the boiler overheat and lock out because the heat cannot get away. Terraces near the cut with long pipe runs and original rads collect it fastest.

Stop resetting it

Three or four resets in a row can leave you with a genuinely damaged heat exchanger instead of a cheap sensor. If it locks out twice, leave it off and call.

Good to know

Boiler Keeps Cutting Out — your questions

It resets and works for a day, then stops again. Is it worth fixing?

Almost always, yes. An intermittent lockout is usually a sensor, a pump or the condensate rather than anything structural. The boilers not worth fixing tend to fail properly and stay failed.

Can I thaw a frozen condensate pipe myself?

Warm water poured along the outside pipe, not boiling, will usually do it, then reset once. If it freezes again the pipe wants lagging or re-routing, which is a proper fix rather than a yearly ritual.

How long does the diagnosis take?

Most of an hour on site. That covers reading the code, checking gas pressure and flue, and ruling out the circulation side, which is what stops you paying for the wrong part.
