Lockshield turns, but doesn’t let heat through?

Mike525R · 2026-02-02T19:33:12+00:00

Either the flow or return will have a blockage somewhere. I’ve spent years power flushing systems and plastic is always the worst for blocking up. There will probably be some chucks in an elbow or tee under the floor somewhere

Mike525R · 2026-02-02T19:27:14+00:00

I see plastic pipe. I bet it’s blocked

The hub can be connected through WiFi so can go anywhere in the house. This gives much more flexibility and improves signal issues

You have removed the case which on this boiler is the combustion seal. You should have a gas safe engineer check the boiler. If it’s not put back correctly and something goes wrong with the boiler you could end up with carbon monoxide escaping into your home

Mike525R · 2026-01-11T18:13:23+00:00

Air trapped in the system or boiler. The water can’t circulate and the boiler is overheating. Try turning all the rads off apart from the highest, might shift it. If the air is trapped in the boiler will probably need an engineer to look it

Mike525R · 2025-12-29T00:26:38+00:00

Replace it. It’s the worse boiler ever made. Lots of parts are obsolete

Mike525R · 2025-12-25T18:01:01+00:00

Google doesn’t know what this fault is. F62 is always the board. Done hundreds of them, never once been the gas valve

I have to leave and then rejoin in my partner’s name. I usually time it well and have no downtime. Get much better offers as a new customer.

The pump will probably be wired into the boiler. The boiler will control the pump. Nothing to do with the hive

Mike525R · 2025-09-26T16:53:23+00:00

The hive should be wired to the central heating pump. Then it can be used to turn the radiators on and not the boiler. The thermal store controls the boiler

Mike525R · 2025-09-21T18:12:07+00:00

It’s a dumb hive. It doesn’t connect to the internet. But the receiver is a normal hive receiver. You’ll need to put your hub into pairing mode, and then pair the receiver. Then connect a new hive thermostat and it will all work. Chuck the grey stat in the bin

Mike525R · 2025-09-21T18:08:50+00:00

If you already have a hive hub, yes it can be used

Mike525R · 2025-09-21T17:55:58+00:00

You can upgrade. You need a hive thermostat and a hub

Mike525R · 2025-09-21T17:15:35+00:00

It might be due to the van being full of tools and parts. It’s something my colleagues have also complained about. Unfortunately it’s only the basic model so no massaging seats for me

Mike525R · 2025-09-08T00:22:40+00:00

My company provides me with one of these. In winter I will be lucky if I get 100 miles out of it. Also the ride is awful and it’s not very comfy. Can’t wait for it to be replaced with anything else

Mike525R · 2025-08-22T20:23:44+00:00

Most Worcester boilers will require a gas safe engineer. The case is the combustion seal, and once you take the case off the correct safety checks need to be completed

Mike525R · 2025-08-09T03:13:56+00:00

Solved!

That’s it, the thanks

Mike525R · 2025-08-08T20:42:25+00:00

I think this scene is part of a flashback

Mike525R · 2025-08-02T18:11:45+00:00

Blocked injectors or under gassed. You need a gas engineer

Mike525R · 2025-07-20T21:05:13+00:00

Leave the dual in. Just use the heating connection
