Mend Suprima Heating Lockout Reset

Suprima locks out ?

After I press reset button for a while it goes back to green light for approx one minute then light starts flashing and finally light goes back to red.

These boilers are notorious for having poor pcbs, but your problem sounds different. It sounds like a start up /ignition failiure.
1: Ensure gas is available
2: Check fan is running and FPS is making
4: Check sparking occuring at burner (not elsewhere)
4: Check for 240v at gas valve

Follow in sequence
