- In case the Auto Door Open device operates, When the door
opening is not sensed.
(Auto Door Open device action retry 3 times)
- Keep going remained cycle.
- The touch button is out of order.
- The sub PBA or touch button PBA is not
properly connected.

Condition 1)
When Main receives the Circulation pump check code from the
inverter, stop the drive the motor and restart again.
If Main receive the motor check code 11 times, turn off the motor
for 5 minutes. At the third rest time, check code occurs. (When
check code occurs, Heater is stopped immediately. And Heater
ON after operating the circulating motor 10 seconds.)
Condition 2)
Washing(Rinsing) area : When Target rpm is 2200rpm or more
and Circulation pump speed is 2000rpm or less continuously for
three seconds, the operation is stopped.
Retry 2 times in 3 seconds. When sensing 3 times, Inverter is
turned off and retry in 5 minutes.
At the third rest time, check code occurs.
(If the condition of Low level water sensing, this check code is
ignored.)
- The driving part stops.
- Retry until 2nd time, and 3rd display check code.
- A foreign object has entered the
Circulation pump and the pump is stuck.
- The Circulation pump is out of order.
- The Main PBA is out of order.
- The Inverter PBA is out of order.

- When the number of detected water supply pulses are 200 at the
Non-water supply mode. → Repeats water valve on(1seconds) /

Case1)
When the reset position sensing for 10 seconds, vane
motor 1 sec Off and re-operation.
Check code occurs after retry three times
Case2)
When the reset position sensing for 25 seconds. Check
code occurs after retry three times.
Case3)
Vane position is the time from initial position to initial
position in 21 seconds or less, the check code occurs.
- Distribute change top and then keep
going remained cycle.
- If while Distribute motor driving, detect the Vane
check code, Stop C-pump and then keep going
remained cycle.
- During Remained cycle, no operating Vane
anymore.
- Motor gear is out of order.
- Sensor vane is out of order.
- When the vane is blocked.
