Ideal faults and what usually causes them

The Logic family shows F and L codes; the Vogue shows the fault in words. The code tells us where to start testing, not which part has failed. These are the ones we are asked about most.

• L2, ignition lockout. The boiler tried to light, failed and has locked itself out. In freezing weather, check the condensate pipe outside first. Otherwise the cause is the gas supply, the electrode, the gas valve or the burner, and it has to be proved on the analyser. On one Ideal Logic, an L2 lockout turned out to be hiding dangerous carbon monoxide readings. We made the boiler safe, replaced the gas valve and injector and recommissioned it. That is why we do not treat L2 as a reset-and-go fault.
• F1, low water pressure. Top up through the filling loop to between 1 and 1.5 bar. If the pressure keeps dropping and there is no leak you can see, the leak may be inside the boiler. On an Ideal Logic that kept losing pressure with no visible leak, we traced it to the main heat exchanger leaking internally.
• F2, flame loss. The burner lit and the flame was then lost. That points to the gas supply, the flue, the electrode or the condensate. Some Logic boilers show this as Fn or Ln, depending on the control board fitted.
• L9 or F9, control board. On Logic combis these codes point to a control board that is faulty or has not been configured. On Logic Max heat-only boilers the same codes are used for a different fault, so we ask for the exact model before anyone prices a board.
• LC, too many resets. The boiler has been reset five times in fifteen minutes and will not accept another. Some models show L5 instead. It is not a new fault: a real fault is being reset, and it needs finding.

Ideal fault codes, briefly

Press reset once. If the code comes back, stop resetting and ring us with the code and the model. The Vogue shows words rather than codes, such as "Ignition Lockout" or "Low Mains Voltage", and they mean what they say. Our guide lists the full set of Ideal fault codes, including the ones that differ between the combi and heat-only models, checked against Ideal's own manuals.

Ideal models we work on

The Logic, Logic+ and Logic Max as combi, system and heat-only boilers, and the Vogue. Ideal changes what some codes mean between models and control boards, so when you call, have the model name and the code on the display. A photo sent by WhatsApp does the same job.

Repair or replace an Ideal?

There is a point at which a boiler is not worth repairing: past twelve years old, on its second or third major part, with a corroding heat exchanger. If yours is there, we will say so and put the repair price and the replacement price side by side. New boilers start at £1,999 fitted, confirmed in writing after a free survey.

The main heat exchanger is the test case. In Willenhall in March 2026 an Ideal Logic was losing pressure regularly, and we traced it to the main heat exchanger leaking internally, one of the most expensive parts inside a boiler. That customer chose a new boiler with a ten-year warranty rather than pay for a major repair; the job is on our Wolverhampton page. Sometimes the repair is worth doing, and sometimes the warranty on a new boiler wins. Our job is to set out both prices so the decision is yours.

Servicing an Ideal

Ideal, like every manufacturer, ties its guarantee to an annual service. A basic service is £95 and includes a combustion check on the analyser; an intermediate service is £125. A full strip-down, £185 with gaskets and an inhibitor top-up included, is the right service when the combustion readings or the condition of the heat exchanger call for it, and we check both at every visit.

What a fouled heat exchanger does to a boiler is easiest to see on a job we photographed, on a different make. A Vokera we serviced read over 999 ppm of carbon monoxide at the start of the visit and 112 ppm after a full strip-down.

Ideal jobs we have attended

We have not yet published a full photo case study of an Ideal repair, and we are not going to borrow one. The Ideal jobs described on this page are the L2 lockout that was hiding carbon monoxide, listed on our boiler repair page, and the Willenhall Logic on our Wolverhampton page. Full write-ups with photos are on the case studies index as we add them.

We also repair Worcester Bosch, Vaillant, Baxi and Glow-worm boilers. Every other make is covered on our main boiler repair page.

Prices

The £99 is a fixed charge for attendance, diagnosis and the first hour in office hours (Mon–Fri 8am–5.30pm); it is not the price of every repair, and parts and further work are quoted and agreed before we carry on. Service prices are the price for the job as described, installation prices are confirmed in writing after a free survey, and out-of-hours work is quoted by phone before we set off. No travel charge within 10 miles of B20 2JS; further out, £2 per mile may apply, agreed before booking. How our prices work.
