Explanations/causes
Check water pressure or fill in water
Lack of gas, contact GW opened, external temperature moni­
tor
Reset, if the fault re-occurs several times contact installer,
lack of gas, polarity of mains connection, safety period, check
ignition electrode and ionization current
Check parameters (see adjustment table installer and/or call-
up values), unlock LMS, replace LMS, installer
Fan possibly defective, speed threshold set wrongly
Check water pressure and drain water if necessary
Check water pressure and top up with water if necessary
