2. Check if the correct machine type is
selected in the S-Menu.
If the wrong machine type is selected, enter
the right machine type.
3. Check if the correct parameters have been
loaded in the inverter.
If the correct parameters are not loaded in the
inverter, load the correct parameters.
4. Check if the fault is persistent. If the fault is persistent, contact the
manufacturer.
DIAGNOSE FOR FAILURE 313: OPT-ERROR
If the inverter doesn't receive requests from the wash computer (= no serial communication), after some
time (about 10-30 seconds), the inverter will go into OPT-alarm state.
1. Check at the end of the wash cycle, if the
power supply contactor of the frequency
inverter switches is switched off on all
phases.
Replace the contactor if the problem is
persistent.
The OPT-ERROR can happen occasionally by a very short general mains power supply interruption.
(Due to the power interruption, the inverter was not able to reset itself correctly.)
=> In such case the contactor must not be replaced. The Inverter must be reset by a longer power
interruption.
DIAGNOSE FOR FAILURE 335: FIN-ERROR
If the heatsink temperature of the inverter crosses it's max allowed operation temperature, the inverter will
go into FIN-alarm state.
1. Check if the cooling fan of the inverter (if
present) rotates normally.
Replace the cooling fan on the inverter (on the
heatsink of the inverter).
2. Check if the cooling fan in the washer that
takes fresh air to the inverter’s environment
(if present) rotates normally.
Replace the cooling fan of the washer.
3. Check if the heatsink or the cooling fans are
not clogged with dust/dirt so that fresh air
can circulate freely.
Clean what is necessary.
4. Check if the ambient temperature of the
washer is within the specified limits (see
installation manual).
Take care that the ambient temperature is
within the specified limits.
FAILURE 150-165: MEMORY ERRORS
If a memory error occurs then something is going wrong with the eeprom.
Try to reload the Programs. Check for source of electrical “noise“.
FAILURE 170-199: SOFTWARE ERRORS
Software errors must never occur. If a software error message occurs inform the manufacturer.
