Ideal boiler fault codes.

Ideal Logic and Vogue boilers show F (fault) and L (lockout) codes. Here’s what the most common ones mean, and what to do about each.

F1

Low water pressure.

Re-pressurise to 1–1.5 bar using the filling loop.

Safe to try
F2

Flame loss.

Check the gas supply and a possible frozen condensate pipe, then reset.

Check, then reset once
F3

Fan fault.

This needs a Gas Safe engineer.

Call an engineer
L2

Ignition lockout: the boiler failed to light.

Check the gas supply and condensate pipe. Reset once. If it locks out again, call us.

Check, then reset once

Codes vary between Ideal models, so check your manual. Reset once only, and never remove the casing.

“Had our new boiler fitted, then a boiler service and a new outside tap since. More than satisfied with the work and the price. Really nice, helpful staff — the office are always pleasant with a lovely attitude. Would highly recommend.”

“Just had Scott fit our new boiler and I can’t praise him enough — professional, tidy, explained clearly what he was doing and cleaned up afterwards. From Scott the fitter to the bubbly, friendly girls in the office, I’d recommend RJ Martindale to everyone.”

“Excellent service at an excellent price from Ryan and his team for 5 years now. My mother-in-law has just had a new boiler thanks to them and started the Homecare plan, which is so much cheaper than British Gas. We have Homecare too and wish we’d done it sooner.”

“We wanted an aircon unit in our main bedroom and it was done quickly, without issue and without any mess — just so tidy. Dan was superb. A few other jobs done at the same time to a very high standard. Would give 6 stars if I could.”

“What a fabulous team. The office staff are so accommodating and pleasant and the workmanship is excellent. Nothing is too much trouble, no short cuts. I’m changing my long-standing home care agreement with British Gas to Martindale’s because I’m so impressed.”

“A Wi-Fi Bosch air con install in our conservatory. Cannot fault the installers, Daniel & Aaron — a neat job with absolutely no mess, and personable chaps who are a credit to the company. We chose Martindales on the back of reviews and their Which? accreditation.”
