rapid flashing light on boilermate a class ov

the central heating went off, the boiler stopped and I found that there was a flashing light on the boilermate . The label says if it is rapid it means "overheat safety trip" What does this mean. I pressed the reset switch and the system is working ok but does it mean there is a problem that needs checking? Thanks for your help. It is not mentioned in the user manual.

I get exactly the same issue. My boiler is 2 years 3 months old in a new build. The issue is happening more frequently and Taylor Wimpey will not send anyone round to look at the issue even though it was first reported within the 2 year warranty period.

Any help in understanding the issue would be greatly appreciated.

Thanks Karl

I'm getting the same problem. The house is a Taylor Wimpey new build that's just 3 years old. No one knows how to cure the problem!!!!! A new Gledhill BP 225 Thermastore is £767.90!!!!

So then, whats the outcome on this discussion / fault???????????
We have also got this fault on a 2 year & 3 month old Gledhill boilermate, it looks as though Gledhill only make these to last this length of time.

I signed up to the British Gas Homecare 200 contract (around £15/month) and they replaced the Gledhill's PCB at no extra charge! They replaced the PCB on the ICOS boiler when it went as well. Took 6 visits to sort it out though. Good luck.
