Symptom
Possible Causes
3E
(3E1 - 3E4)
Condition 1
)
- When Main receives the Circulation pump error from
the inverter, stop the drive the motor and restart again.
If Main receive the motor error 11 times, turn off the
motor for 5 minutes. At the third rest time, Error occurs.
(When an error occurs, Heater is stopped immediately.
And Heater ON after operating the circulating motor
10 seconds.)
Condition 2)
- Washing(Rinsing) area : When Target rpm is 2600rpm
or more and Circulation pump speed is 2400rpm 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, Error occurs.
(If the condition of Low level water sensing, this error is
ignored.)
- 20 seconds ON/ 5 minute OFF. Drain for 3 minute.
- Any dirt or other remains are stuck in circulation pump and pump.
- The Circulation pump is out of order.
- The Main PBA is out of order.
The Inverter PBA is out of order.
4E5
- When the number of detected water supply pulses are
200 at the Non-water supply mode.
→
Repeats water valve on(1seconds) / off(1seconds)
2 times
- Draining (20 seconds on/5 seconds off) is performed
for 3 minutes, and then 200pulse over again detected,
repeat Draining.
- The water valve is out of order.
9E1
If blackout or DC Link voltage is high or low voltage
conditions, switches to stop mode (abnormal voltage).
- The driving part stops.
- High or Low voltage is supplied.
7E
Case1) When the reset position sensing for 10 seconds,
vane motor 1 sec Off and re-operation.
Error occurs after retry three times.
Case2) When the reset position sensing for 25 seconds.
Error occurs after retry three times.
Case3) Vane position is the time from initial position to initial
position in 21 seconds or less, the error occurs.
- Draining (20 seconds on/5 seconds off) is performed
for 3 minutes.
- Motor gear is out of order.
- Sensor vane is out of order.
- When the vane is blocked.
