Main Heat 12 boiler lockout

Hi Folks,

My newly bought and installed Main Heat 12 boiler is locking out a lot. As I shared that, my boiler is quite new but I have faced this problem many times. The boiler is under warranty, should I call a service center or replace the boiler? Moreover, I have restarted the boiler but as I turned it on, the boiler immediately goes to a lockout state. Please help me because I am extremely worried.



Hi Tony, the boiler goes to in a lockout state due to several unforeseen reasons. When the boiler lockouts as you press a reset button then, it is possibly because of the control or wiring issue. You cannot fix it on your own therefore; call a proficient Main boiler engineer.
