button, the control tries to initiate a restart if possible
ERROR CODE DESCRIPTION REASON ACTION RESET P
O
OSSIBLE
1 Overheated CH Water temperature •Check no air is in heat exchanger/CH system
appliance greater than 105°C •Check plate heat exchanger for blockages Y
•Check CH thermistor
•Check system bypass is functional
4 No flame No flame signal on ignition •Check detection electrode/lead – electrode may require cleaning
•Check spark gap
•Check gas supply & pressure Y
•Check flue system is connected properly
•Check condensate trap not blocked
•Check gas valve and/or lead
5 Flame loss Loss of flame signal •Check detection electrode/lead
during operation •Check gas valve mains lead
6 Temporarily Water temperature •Check overheat thermostat
overheated appliance greater than 95°C •Check no air is in heat exchanger/CH system
•CH system and hot water plate heat exchanger blockage Auto Re-start after 1 minute
•Check CH thermistor
•Check system bypass is functional
7 Overheated appliance Flue over temperature •Check no air in heat exchanger
> 92°C •Check flue thermistor
•Check flue system Y
•Check pump
•Check PCB/X8 connector
11 Flame simulation Flame detected when •Check detection electrode/lead electrode may require cleaning
gas valve closed •Check gas valve operation.
41 Water flow failure/ Low water pressure •Check CH flow circulation
Flame for a short Reversed sensors •Check water pressure(> 0.5 bar)
period only •Check pump/lead Y
•Check expansion vessel
•Check flow and return sensors connected correct way around
42 Water flow failure/ Low water pressure •Check no air in heat exchanger
Flame for a short No flow •Check CH flow circulation
period only Dry run protection •Check water pressure(> 0.5 bar) Y
•Check pump/lead
•Check expansion vessel
