Warmda Fault and Error Codes

E01 Flame sensor open circuited Please connect the lead properly if it's loose.
E02 Flame sensor short circuited Use multimeter to check if the flame sensor is short circuited or open circuited. Please repair or replace it if true.
Use multimeter to check if the flame sensor is broken. Please replace it if true.
E03 Flame temperature exceeds the maximum safe temperature Check if the air inlet, outlet and the exhaust pipe are blocked. Please clean up if true.
E04 Flame temperature is lower than the minimum ignition temperature; ignition failure Check whether there is fuel inside the tank. If not, please refuel.
Check whether the fuel pipe is blocked, and whether the connection is correct. If not, please repair or replace it.
Check whether the fuel is frozen. If true, please use fuel suitable for low-temperature environment.
Check whether the exhaust pipe is blocked. If true, please clean it up.
Please replace the controller
E05 Air sensor open circuited Please check the plug of the air sensor.
E06 Air sensor short circuited Please contact the dealer or manufacturer.
E07 Overhigh supply voltage Use multimeter to check the voltage of power. If it's lower than DC 20V, please charge the battery or use a new one; if it's higher than DC 30V, please use a new battery.
E08 Over or low supply voltage Use multimeter to check the voltage of power. If it's lower than DC 10V, please charge the battery or use a new one; if it's higher than DC 15V, please use a new battery.
E09 Glow pin grounded Check if the glow pin is broken. If true, please replace it; use multimeter to check the resistance value between two leads of the glow pin. The value should be within 1-4 Ohm. Please replace it if not.
E11 Glow pin open circuited Please connect the lead properly if it's loose.
E12 Fan motor open circuited Please connect the electric motor plug properly if it's loose.
E13 Fan motor short circuited Test (electrically) the electric motor to see if it operates properly. Please replace it if not.
E14 Electromagnetic pump failure Please connect the lead properly if it's loose.
E15 Electromagnetic pump failure Use multimeter to check the resistance value of fuel pump. It should be within 15-25 Ohm. Please replace it if the value is out of range.
E16 Heater offline (serial port error between the main board and the heater) Please correct the serial connection.
E17 Altitude sensor failure (fail to read the altitude) Please repair or replace the altitude sensor.
E18 Reserved
E19 Boot failure of the heater Please check whether there is fuel in the fuel tank; check whether there is carbon in the air outlet. If true, please clean the carbon; Aging of glow pin.
