Customer Question
Hi, I have a...

Hi, I have a glow worm Flexicom Cole boiler which has come up with code F4 and there is no hot water from the taps or in the radiator system. I am trying to find out how I may be able to fix this? Thanks

Contractor's Assistant: How long has this been going on? And how severe is the problem?

It started last night although the boiler was becoming noisy a week ago

Contractor's Assistant: Do you plan on doing the work yourself?

It depends on how it can be fixed

Contractor's Assistant: Anything else we should know to help you best?

I don't think so. Thank you

Hi F4 could mean any number of faults.

Here are some.

Gas tap is closed
Gas valve connector is loose,unconnected,faultly,or wires are trapped
Ignitor connectors are loose,unconnected,faultly,trapped
Faulty ignitor
Low gas inlet pressure
Incorrect gas valve adjustment
Electrode ignition leads loose,unconnected,faulty,trapped
Electrode broken,defective, or position incorrect
Air inlet blocked,flue inlet blocked,flue duct leaking
Earthning connection loose,disconnected
Condesate blocked.

I would suggest you reset the boiler first.

If that doesnt work and your not familiar with the workings of a boiler. Get someone in.
