7) EF error
- Cause : When Flow-sensor abnormal. ( There is no pulse during some time. )
The number of pulse signal is below 10 by 1 second during water supply.
- Check point : Water supply line.
8) Et error
- Cause : Level switch abnormal. ( No pulse is sensed for some time. )
- Control : By time. ( Supply mode is skipped. )
9) Eg error
- Cause : When Ice sensor temperature ( 5 minutes after water supply ) doesn't go up.
- Check point : Ice sensor or water supply line.
10) EA error
- Cause : When sensing ice drop 3 times in level sensor switch error.
- Control : Stop ice maker
- After 1 time rotation EA error code disappear if level swtich is normal.
11) Eu error
- Cause : Sensor which senses if ice is full or not is abnormal.
- Control : When drops the ice, the motor rotates 90 degree.
12) C1 error
- Cause : When compressor works for over 3 hours although Defrost sensor is over -5C.
- Check point : Refrigerant leakage.
13) F3 error
- Cause : in case defrosting mode ends after 80 minutes.
- Check point : Measure the resistance between both terminals of the defrost heater.
If the resistance is infinity (disconnection) or 0 ohm (short).
