HELP CODE H63 : INITIALIZATION FAULT INVERTER
While the parameter set of the frequency inverter is written to the EEPROM memory of the inverter and a
fault occurs during this action then Help Code H63 will be displayed.
IT IS NOT RECOMMENDED TO USE THE WASHING MACHINE AS THE INVERTER WILL FUNCTION
WITH THE WRONG PARAMETERS SETTINGS.
Diagnose(ERR31):
1. Check if the door is closed and locked
2. Check if the inverter is energized
3. Write the parameters once more into the
inverter
HELP CODE H64 : VERIFICATION FAULT INVERTER
The software of the electronic timer will check if the parameter settings are correct loaded. If not:
Help Code H64 will be displayed. Help Code H64 can not be reset by the ENTER button.
The fault message can be erased by switching the power off / on.
The fault message can be erased by loading the correct parameter set.
DIAGNOSE(ERR32):
1. Check if the correct machine type is
selected in the Configuration Menu
2. Check if the door is closed and locked
3. Check if the inverter is energized
4. Write the parameters once more into the
inverter
HELP CODE H65 : STALL PREVENTION FUNCTION
This fault number indicates that the stall prevention of the frequency inverter is functioning now and then.
The fault number is not displayed at the end of the program cycle. The number is only written to the error log
register. The stall prevention function will only be activated to protect the motor for over current.
This fault number is an indication that there is to much laundry loaded. It is also possible that due to the
laundry the drum is not balanced what will produce an extra load for the motor.
DIAGNOSE(ERR33):
1. Check if the drum is not overloaded
2. Check if the correct machine type has been
selected in the Config menu
3. Check if the correct inverter parameters
have been implemented.
4. Check if there are mechanical parts broken

If the door is not closed, close the door. If the door is
not locked, repair the door lock system
If the inverter is not energized, check the power to the
inverter (see fault 27)
If the fault is persistent, contact the manufacturer
If the wrong machine type is selected, enter the right
machine type
If the door is not closed, close the door
If the door is not locked, repair the door lock system
If the inverter is not energized, check the power to the
inverter (see fault 27)
If the fault is persistent, contact the manufacturer
Enter the correct amount of laundry in the drum
The installed parameters are related to the motor and
machine type size. If a wrong machine type was
selected then the stall prevention will function for the
wrong motor type. Select the right machine type.
Load the correct Inverter parameters.
Broken parts can cause an unbalance of the drum.
Replace the broken parts.
