Check plate heat exchanger
26
Gas valve closed
Open gas valve
27
No gas supply
Gas pressure regulator stuck or broken, gas valve closed, check grid pressure
28
Ignition cable broken or not connected
Check ignition cable
29
Ignition cable cap damaged
Check for cracks. Replace when required
30
Ignition transformer damaged
Check if the unit sparks and check the distance and gap of the electrode. If all OK replace burner
controller.
31
Water in ionisation circuit

32
Dirt in gas valve
Check if valve fully closes when power is unplugged
33
Flue gas sensor damaged
Exchange sensor and check parameter 14
34
Wrong setting of temperature limit configuration
Check parameter 14
35
Maximum power too high
Check boiler power and adjust parameter 1 when required
39
Pump does not run is stuck
Replace pump or try to turn pump shaft.
40
Refill valve is open
Close refill valve
41
Cable damaged
Check cables for damage and friction free routing
42
Sensors switched
Check sensor positions and connections
43
Supple sensor broken
Check sensor in diagnose menu (4) and replace when required
44
Siphon cluttered (condensate cup)
Clean siphon
45
Too high circulation losses or demand
Boiler is not able to heat tank to a temperature above 70C within 3 hours. Check recirculation losses and
heat exchanger tank
46
Gas valve cables damaged
Check cables and replace when required.
47
Gas valve broken
Check gas valve and replace when required.
48
Leakage in CH circuit
Exchange leaking installation part s and refill
49
CH pressure too high
Decrease pressure using the drain valve
50
Expansion vessel broken
Check expansion vessel
51
No temperature rise detected within 1 minute
Check position of supply sensor and flue gas sensor. Check sensor readings via diagnose menu and
after ignition or sensor broken
replace sensor(s) when required
52
No outdoor sensor connected
Check parameter 7
53
Outdoor sensor broken
Check reading via diagnose menu (11) and replace sensor when required
54
CH return sensor broken
Check reading via diagnose menu (6) and replace sensor when required
55
Supply voltage too low
Check supply voltage in standby and operation
56
Supply cable damaged
Replace supply cable
57
Fan not connected
Check fan connection to burner control
58
Too much dust/dirt in fan
Check and clean fan
59
Fan broken
Replace fan
60
Water on fan connection
Check fan and connection and make dry when required
61
CH pressure sensor broken
