ID7308 WKF fault code E464
Overcurrent at the inverter module IPM (IGBT transistor
module). Check software status for the motherboard
ID7309 WKF fault code E425
Phase fault malfunction. A phase conductor is missing at the
frequency converter (can only occur with WKF 180 - other-
wise, check motherboard version)
ID7310 WKF fault code E203
Communication error between motherboard (7-segment dis-
play) and inverter board
ID7311 WKF fault code E466
Under-voltage or over-voltage in the intermediate DC circuit of
the inverter.
ID7312 WKF fault code E469
Voltage probe fault in the intermediate DC circuit of the
inverter. Replace inverter board if necessary
ID7313 WKF fault code E458
Implausibly high current at the current probe or fault at the
BLDC motor for fan 1.
ID7314 WKF fault code E475
Fault at the BLDC motor for fan 2
ID7315 WKF fault code E461
Implausibly low current at the current probe or fault on the
inverter board at compressor start (can occur with compressor
damage)
ID7316 WKF fault code E467
Missing phase conductor on the compressor
ID7317 WKF fault code E462
Overcurrent fault (primary side) - check power supply / fuse
for the EMI board
ID7318 WKF fault code E463
Compressor overtemperature (OLP). Probe value greater than
115 °C (below 12.7 k
W
). Can be caused by a jammed expan-
sion valve
ID7319 WKF fault code E554
Refrigerant quantity / refrigerant loss malfunction
ID7320 WKF fault code E556
Power ratings for the com. kit board (IM) and the motherboard
(AM) differ - check board versions.
ID7328
Open contact -
2nd mixed heating cycle
inlet temp.
S06
