Malfunction
Error
code
Reason Solution
Communication failure
between controller and
main board
EE08
1. Poor signal wire connection or
damaged signal wire
2. Controller malfunction
1. Check and re-connect the
signal wire
2. Change a new signal wire
3. Turn off electricity supply and
restart machine
4. Change anew controller
Communication failure
between Main control
board and Driving board
EE09
1. Poor connection of
communication wire
2. The wire is damaged
1. Check the wire connection
2. Change a new wire
VDC voltage too high
protection
EE10
1. Mother line voltage is too high
2. Driver board is damaged.
1. Check if the power is in the
normal range
2. Change driver board or main
board
IPM module protection EE11
1. Data mistake
2. Wrong
compressor phase
connection
3. Compressor liquid and oil
accumulation lead to the current
becomes larger
4. Compressor or driver board
damaged
1. Program error, turn off
electricity supply and restart
after 3 minutes
2. Change driver board
3.
Check compressor
sequence connection
VDC voltage too low
protection
EE12
1. Mother line voltage is too low
2. Driver board is damaged.
1. Check if the power is in the
normal range
2. Change driver board
Input current over high
protection.
EE13
1. The compressor current is too
large momentary
2. The water flow is abnormal
3. Power fluctuations within a
short time
4. Wrong PFC inductor 1. Check the compressor
2. Check the waterway system
3. Check if the power is in the
normal range
4. Check if the correct PFC
inductor is used
IPM module thermal circuit
is abnormal
EE14
1. Output abnormity of IPM
module thermal circuit
2. Fan motor is abnormal or
damaged
Fan blade is broken
1. Change a driver board
2. Check if the motor speed is
too low or fan motor damaged,
change another one
3. Change another fan blade
