DIAGNOSE FAILURE 313/315: OPT/PUE-ERROR (OPTION FAULT/PARAMETER UNIT LEAVE OUT)
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/PUE-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.
The OPT/PUE-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 FAILURE 335: FIN-ERROR (COOLING FIN INVERTER OVERHEAT)
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.
2. Check if the cooling fan in the washer that
takes fresh air to the inverter's environment
(if present) rotates normally.
3. Check if the heatsink or the cooling fans are
not clogged with dust/dirt so that fresh air
can circulate freely.
4. Check if the ambient temperature of the
washer is within the specified limits
(see installation manual).
FAILURE 500-525: MEMORY ERRORS
If a memory error occurs then something is going wrong with the EEPROM.
Try to reload the washing Programs. Check for source of electrical „noise".
FAILURE 550: TRACEABILITY WRITE
The failure 550 is a failure of the wash computer internal memory. This failure message appears after a failed
attempt to write the Traceability into the internal memory. Change the CPU control board.
(Traceability function can be switched off in the Advanced Menu.)
FAILURE 551: TRACEABILITY FULL
The failure message 551 is displayed if the Traceability data fill up the internal memory of the wash computer.
The Traceability data need to be "cleaned" utilizing a PC software.
As a consequence of the failure no data of the wash cycle can be saved.
(Traceability function can be switched off in the Advanced Menu.)
FAILURE 600-628: SOFTWARE ERRORS
Software errors must never occur. If a software error message occurs inform the manufacturer.

Replace the contactor if the problem is persistent.
Replace the cooling fan on the inverter (on the
heatsink of the inverter).
Replace the cooling fan of the washer.
Clean what is necessary.
Take care that the ambient temperature is within
the specified limits.
