11:28 WATER LEVEL HIGH DLCU LEVEL LOW
The DLCU on I/O type 10 contains a mechanical DLCU level switch which ensures that there is no water in the ma-
chine when the door unlocks. To ensure that the DLCU level switch functions correctly, the DLCU level switch status
is compared with a predefined value from the electronic level sensor. During first fill, this check is made to ensure that
the mechanical level switch is activated when the water level exceeds the predefined value. If not, this error code is
shown.
Predefined level value is defined in Config. 2 parameter LEVEL DLCU.
Possible causes:
• The mechanical level control can be damaged.
• Leakage or clogged level controls air hoses.
Recommended actions:
1. Check function of mechanical level switch by reading DLCU status in service mode.
2. Check the analog level control function by checking value in inputs.
3. Blow through the level hoses and check that they are not blocked and does not contain any water.
4. Check the cables and their connections.
