Worcester Boiler is crashing/lockout randomly when using central heating.

[matt50]

Hello, I've previously had an issue with my boiler pressure getting too high with the central heating on and needing a reset. I had a gas plumber come round and he swapped the expansion vessel. The pressure issue seems to be fixed but now there is another issue...

When I turn the central heating on, the radiators will start to warm up but the boiler will crash/need reset. This happens at random times after I turn the CH on, it could crash after 10 minutes or 30 mins ... or over an hour. The pressure always seems okay - 1.5 to 2.

If I only use the hot water then I have no problems. It's a Worcester combi boiler

The gas man had a look over the connections again and said the next step is replacing the nodes?... and then PCB and Gas valve. This could end up costing a lot. Any advice on how I should proceed?
The error code is a consistent blink, an even on/off rhythm.. I was told this is an ignition error...
Many thanks

You need a gas engineer who can fault find and not just chuck part after part at it.

Agreed about the engineer. No fault code?

If it looks like looking costly contact WB for a fixed price repair.

Edit: they don't seem to offer it anymore Shaun?

Yep they still do it think it’s gone up tho £325 but they will replace parts until it’s fixed

Thanks guys. The fixed price option looks interesting. Now I've looked into it.... I see British gas offer a fix and 12 month cover for £300.. which seems like a better deal unless I'm missing something?

Repair & Cover - British Gas

Get your boiler fixed for just £75. Then just sign up for 12 months Central Heating Breakdown Cover for £26 a month to be covered for the whole year.

That does seem like a better deal with cover but my instincts would still be to go with WB fixed price. Depends where this is going as Shaun says if a big ticket item like the hex or PCB needed replacing WB would throw parts at it till it's fixed but I suspect BG would drag their feet to minimize their outlay. If it's a simpler less costly fix then the BG deal makes more sense.

And bg would have to order parts normally the Worcester lads have everything on the van
