I have a Baxi Solo HE boiler and yesterday evening, for no apparent reason, the boiler tripped out. Both HW and CH lights on the controller were on, the lockout light on the boiler was on and the ''Mains On'' and ''Boiler On'' lights were both out. I pressed the lockout switch, the power light came on and the the boiler started. It worked OK for the rest of the evening.
This morning the heating did not come on and I found the same situation - lockout on and the green lights both off. Again, I pressed the lockout button and the boiler started. It is still running as I write this.
An additional bit of information: this morning, with the boiler tripped, the pump appeared to be running, but all the pipes in the landing cabinet containing the pump and the Megaflow tank were cold. The boiler is in the garage.
Can anyone suggest what might be the fault. The maker's fault finding charts don't seem to cover this problem.
