I have a Mexico 2 boiler that cuts 0ff the main burner after about 5 minuets. The room stat is calling for heat, the hot water stat is calling for heat, the boiler stat is calling for heat. The pump is working (the rads start to warm up) the 3-way valve is working. The pilot light is always on. This is a propane boiler. Any ideas? Thanks.
In addition to the above, the company that have been called to check the boiler have said that it may be the solenoid in the gas valve and are recommending a new boiler as the valve cost is £250-ish., and the boiler is old.
