WARNING
Description
The hot/cold water hose connection is
not correct.
Suds is detected during the washing
session. ("SUd" or "Sd" is not an error.
When it finishes washing, End and the
"SUd" or "Sd" code will blink in turn.)
Communication error between SUB PBA
and MAIN PBA.
If the MEMS communication error or
MEMS trouble diagnosis error occur, this
message will be displayed.
A button except the Power button is
continually pressed.
The hot/cold water hose connection
is not correct.
This error occurs when the position
of the clutch is not detected.
- If the position detection signal is
not received 15 seconds after the
clutch motor starts, the spin drum is
shaken left and right and then the
motor is restarted.
If the motor position signal is not
received even after 3 reattempts, a
PE error occurs.
After the completion of the clutch
position detection, and the clutch
hall signal is invalid, the spin drum
is shaken left and right and then the
clutch hall signal is evaluated again.
This, if the clutch hall signal is still
invalid, the clutch position switching
status is checked and then the
operation is restarted.
(If the 15 reattempts fail, this error
occurs.)
