5-7. E4 Error - Error in the Detection of Water Leaks
1) Water is resupplied over 20 times during a wash cycle. -> This rarely occurs due to the short cycle duration.
2) The motor stops running and the 'E4' error appears on the display panel.
3) If the Power button is turned off and on, the error display disappears.
5-8. Errors in Motor
1) b1 Error (Error in HALL IC signals)
2) b2 Error (EMG or IPMFAULT)
1
The error occurs when electric current of 15A or higher flows into the shunt resistance of IPM-MODULE.
The function is to protect PCB from the motor overheating.
2
The motor stops running, and 30 retrials are made. Then, the 'b2' error appears on the display panel.
3
If the Power button is turned off and on, the error display disappears.
3) b3 Error (Motor overload error)
4) b4 Error (Failure in motor arrangement)
5) b5 Error (Failure in tracking the motor speed)
6) b6 Error (Error in DC LINK overvoltage)
7) b7 Error (Error in DC LINK low voltage)
8) b8 Error (Failure in starting motor)
1
The error is caused by failure to rotate the motor due to the initial overrunning of motor.
2
The motor stops running, and 30 retrials are made. Then, the 'b8' error appears on the display panel.
3
If the Power button is turned off and on, the error display disappears.
