Malfunction
Error
code
Reason Solution
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 reactor
1. Check the compressor if it works
normally
2. Check the waterway system
3. Check if the power is in the normal range
4. Check if the reactor is used correctly.
IPM module thermal
circuit is abnormal
EE14
1. Output abnormity of IPM module
thermal circuit
2. Fan motor is abnormal or damaged
3. Fan blade is broken
1. Check if the motor speed is too low or
fan motor is damaged, replace it by anew
one.
2. Replace a new driver board
3. Change the fan blade if it is broken
IPM module
temperature too high
protection
EE15
1. Output exception of IPM module
thermal circuit
2. Fan motor is abnormal or damaged
3. Fan blade is broken
4.The screw on driver board is loose
1. Check the main board or replace the
driver board
2. Check if the motor speed is too low or
fan motor is damaged, replace it by anew
one if any failure.

DC fan motor failure EE17
1. DC motor is damaged
2. For the tri-phase check if the
neutral is connected
3. Main board is damaged
4. The fan blade is stuck
1. Detect DC motor for mono phase
machine, replace a new one if any failure
2. Check the wiring connection for tri-phase
machine
3. Check the board, replace a new driver
board or main board if any failure
4. Check if there is any barrier in front of
fan blade and remove it
PFC module thermal
circuit is abnormal
EE18 The driver board is damaged
1. Check if the motor speed is too low or
fan motor is damaged, replace it by anew
one.
2. Change a new driver board
