Published 10 April 2026 · Generated by BoilerTag's diagnostic AI from an engineer's real-world submission
One of 13 real-world fault checklists on BoilerTag, across 5 boiler makes.
Most likely cause
The Ideal Vogue Max Combi 26 displaying 'IGNITION LOCKOUT' indicates that the boiler has failed to ignite after several attempts and has entered a safety lockout mode. This is a common safety feature to prevent dangerous situations. The boiler will not make any noises, provide hot water, or heating until the fault is cleared and the system is reset. Common causes include issues with the gas supply, a blocked condensate pipe, or faulty ignition components.
The engineer's report
A gas engineer submitted this case through BoilerTag's free fault diagnostic tool, working on a Ideal Vogue Max Combi 26 displaying fault code IGNITION LOCKOUT. They described the behaviour they were seeing on site as follows:
“hi my boiler is showing IGNITION LOCKOUT and then it says Ignition Lockout under it. it doesnt make any noises at all, no beeps or clicks or anything. just totally silent. there's no hot water or heating. the display just shows that message constantly. it doesnt even try to do anything, just stuck on that screen. the pressure gauge on the front looks ok, its in the green zone. it happened all of a sudden this morning, was fine yesterday.”
Before requesting the AI diagnostic, the engineer had already worked through the following checks:
“ive tried pressing the reset button a few times but it just comes straight back to the same message. checked the condensate pipe outside & it looks clear. also checked other gas things in the house & they're working fine so it's not the gas supply i think. my prepayment meter has plenty of credit too.”
