Identifiable fault codes recurring and intermittent issues - Keston C36 Fault codes E01 to E99 common faults; E03 E06 E23 E24 E26 E35 E37 ERROR CODES

December 22, 2016

Keston C36 Fault codes E01 to E99 common faults; E03 E06 E23 E24 E26 E35 E37

ERROR CODES 

 

E99 As E41 

 

E46 Flue sensor open circuit - check connections to flue sensor are in place 

E45 Flue sensor short circuit - check connections to flue sensor 

E44 Return sensor open circuit - check connections to return sensor are in place 

E43 Return sensor short circuit - check connections to return sensor 

E41 Communication error between fascia and control box - check cables 

E40 Water pressure too high - check expansion vessel charge and operation 

E38 Reset key fault - replace fascia PCB 

E37 Water pressure error - check system pressure and pressure sensor

E35 Mains supply frequency incorrect - Check mains voltage system in dwelling 

E34 Mains supply voltage < 180V - Check mains voltage system in dwelling 

E33 DHW sensor open circuit - check connections to DHW sensor are in place 

E32 DHW sensor short circuit - check connections to DHW sensor 

E31 Flow sensor open circuit - check connections to flow sensor are in place 

E30 Flow sensor short circuit - check connections to flow sensor Flame signal lost 5 times in 4 minutes - The flame is unstable, check combustion, gas supply, air supply and flue. E26 E25 Control box errors - possible faulty control box. 

E24 Water pressure lost 4 times in 24 hours - possible leak, check system and boiler. 

E23 Water filling error - check water pressure sensor. 

E12 to E22 Control box errors - possible faulty control box. The automatic test for calibration of flow and return sensors has failed. Check both flow and return sensors are located on the correct pipes and are producing the correct readings. 

E11 E10 Control box errors - possible faulty control box. 

E09 Valve drive error - possible gas valve or control box fault. 

E08 Flame circuit error - possible control box fault.. Flue overheat - check combustion and flue temperature vs. return temperature (Installer numbers 7 and 3 above). The flue temperature should be no more than 10C above return temperature. Possible heat exchanger fault 

E07 Fan failure - boiler cannot detect fan rotation. Check fan operation and BOTH connectors onto fan. 

E05 Boiler overheat - check system for blockage, by-pass provision and pump operation 

E03 False flame - the unit is detecting a flame BEFORE ignition. Check gas valve closure, power supply polarity and voltage and earth connection. 

E02 Ignition failure - the boiler has attempted to light five times and not succeeded - check gas supply, air supply, flue, ignitor condition and spark gap.
