Troubleshooting
Error code 07, OVERFILLED
This error code is generated by the CPU board. The error code arises if
the drum has been filled with water above a predetermined level during an
on-going wash program. It can be caused by a blocked level hose, drops
of water in the level tube, defective filler valve, defective electronic filler
control, etc.

Error code 08, NO HEATING
This error code is generated by the CPU board. The error code means that
the temperature is rising too slowly when heating is active. The limit for this
error code is normally set to a water temperature increase of approx. 3°C
per 10 minutes but can vary depending on the type of machine and the
software.
The error code can be caused by a defective heater element, a break in
the power supply to the heater element, defective heater contactor, etc.
On machines built for washing mops, it can be caused by too low a level in
the program stage. The lowest level for a mop program in the main wash
with heating is 90 scale units.
