Ignition lockout Halstead Best 60 boiler

I called in the engineers after the ignition on my Halstead Best 60 kept locking out. They have replaced the actuator and the pump on the CH system, and the aquastat in the boiler somewhere, and timer controller, AND a full all-day power flush but to no avail - the ignition is still locking out. This has now cost well over £1500 so I am getting very frustrated.

I am not going to attempt any DIY on this but would very much like some helpful advice from someone on the forum who has experience of fixing such issues!

Check the venturi on the fan make sure its clean but its a job for an engineer

British Gas do a fixed price repair for about £180.

I would come and spend a few days working on it for £1000 whilst staying at a local hotel.

In fact I only need about £110 per day overnight expenses so could probably just charge travelling plus our daily rate.

But the nearby gas installers would have fitted a better boiler for £1500 or less.

If you have an "Ignition" Lockout and NOT "Overheat" Lockout, then the Person you have hadin has changed just about every part that is NOT RELEVENT to your problem, intermittant lockouts on these boilers are often due to a faulty gas control valve, the Red Honeywell combustion pcb or has already been mentioned the fan venturi, personally if your description of events is acurate I'd be asking for my money back
