E19, E20, E27, E50, E54, E57, E58, E59, E60, E61
Indicates internal CPU diagnostic self-test has returned invalid results.
Possible reasons:-
• EMC issue (try twisting ignition cable around thermocouple wire several times to quench radiated
EMC emissions).
• Spark tracking out somewhere other than at electrode causing unusual interference.
NOT APPLICABLE.
RESERVED FOR FUTURE USE.
Indicates valve has performed 40k start operations.
END OF LIFE – valve has produced more than 40,000 burner starts.
Under normal use 40,000 starts will allow for 7 starts per day, every day, for more than 15 years.
Indicates the thermocouple has not reached nominal final temperature within 1 minute of startup.
Possible reasons:-
• Aged thermocouple.
• Thermocouple wire insulation is damaged and shorting to metal chassis.
• Problems with chimney, or room, air inlets (insufficient air circulation).
• Unstable pilot flame (e.g. wind, unsuitable thermocouple position).
• Contaminated pilot (poor flame to thermocouple).
• Poor position of ceramic parts (e.g. coals, logs, or matrix).
Indicates power supply with incorrect pin orientation connected to USB inlet.
E32, E43, E46, E47, E52, E53, E55, E56, E62
Indicates self-test procedure of valve electronics has failed.
Possible reasons:-
• Completely flat batteries.
• Liquid ingress affecting electronics (e.g. following leak test with soapy water).
