FAILURE 28: THT (Mitsubishi) TIME OUT
Fault 28 occurs when the wash computer can not handle the THT (Mitsubishi) / E.OL (KEB) fault of the
frequency inverter.
This fault is a specific fault of the frequency inverter caused by an over current.
DIAGNOSE:
1. Check if the correct machine type
is selected at the Configuration Menu.
2. Check if the dedicated inverter parameters
have been loaded by the wash computer.
3. Check if the power supply is sufficient high
and stable during extraction with load.
4. Check if the drum rotates normally by hand.
5. Check if the fault is persistent.
FAILURE 29: OV3 (Mitsubishi) TIME OUT
Fault 29 occurs when the wash computer can not handle the OV3 (Mitsubishi).
This fault is a specific fault of the frequency inverter caused by an overvoltage.
DIAGNOSE:
1. Check if the correct machine type
is selected at the Configuration menu.
2. Check if the dedicated inverter parameters
have been loaded by the wash computer.
3. Check if there was a high unbalance during
extraction, which can be caused by putting
only half loads in the machine.
4. Check if the fault is persistent.
FAILURE 31: INITIALIZATION FAULT INVERTER
Fault 31 occurs when something goes wrong while the wash computer writes the dedicated inverter
parameters into the inverter EEPROM memory. This fault message means that not all dedicated inverter
parameters have been loaded. As a result the inverter will not work in a correct way.
IT IS NOT RECOMMENDED TO USE THE WASHING MACHINE AS THE INVERTER WILL FUNCTION
WITH THE WRONG PARAMETERS SETTINGS.
DIAGNOSE:
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.
540876_A_PUB_DATE_1_FEB_2012.DOC
If the wrong machine type is selected, enter the right
machine type.
Load the correct Inverter parameters.
Repair the power supply.
Repair / clean what is necessary.
If the fault is persistent, contact the manufacturer.
If the wrong machine type is selected, enter the right
machine type.
Load the correct Inverter parameters.
Put always a full load in the machine drum.
Do not put other material than textile linen (fabrics)
in the machine.
If the fault is persistent, contact the manufacturer.
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.
