Fault Code
Possible problem
Description
E1
Pan or pot fault
No pan or pot, or their size, material, etc. is not suitable, or
not placed precisely in the middle of the cooking area.
E2
Voltage is too high
Higher than AC 265V.
E3
Voltage is too high
Lower than AC 180V.
E4
IGBT sensor open-circuit
When the IGBT sensor detects an open-circuit, the IGBT
sensor stops working.
E5
IGBT sensor short-circuit
When the IGBT sensor detects an short-circuit, the IGBT
sensor stops working.
E6
IGBT sensor over temperature
IGBT reaches 110
±
5
℃
for 3s(It can recover automatically
when temperature decrease 50
℃
-70
℃
).
E7
Hob surface sensor open-circuit
After 60 seconds of operation, IGBT stops working when
the temperature detection circuit of pot has detected an
open-circuit.
E8
Hob surface sensor short-circuit
IGBT stops working when the temperature detection circuit
of pot has detected an short-circuit.
E9
High temperature protection of
pot sensor
IGBT stops working when the temperature detection circuit
of the pot is detected to exceed a certain value.
EA
Pot sensor removal or failure
protection
When the pot sensor is moved out, and the whole machine
is heated for a period of time, the corresponding area will
detect the moving out state of the cooker sensor, and the
heating area will stop heating.
EB
Communication fault
The power board does not receive a valid communication
signal from the display board for 90 seconds.
EC
Communication fault
The display board does not receive a valid communication
signal from the power board for 90 seconds.
H
Hob surface is of high
temperature.
After the hob is off, if the hob surface temperature is too
high, it will display "H", and the fan will delay working for 2
minutes.
