Red neon light comes on when i try to turn on the heating saying fault on the pump, low pressure. Pressure guage is down to zero. How do i fix the pressure?
you need to get the pressure back up on the boiler, its normally up in the hot press theres a filling valve up there to fill the system back up and only fill it to 1mb on the gauge and make sure u dont over fill it close it off at 1 mb
