11:27 LEVEL OFFSET
This error code is shown at program start if the level sensor indicates a level above what the control
system CPU can compensate for. If high level is indicated a attempt is made to first drain the
machine.
Maximum allowed level offset is defined in Config. 2 parameter MAX LEV. ZERO OFFS.
The drain time before error code is triggered is defined in Config. 2 parameter MAX DRAIN TIME
START.
Possible causes:
This error can be caused by defective level control, blocked drain, blocked level hose, a drop of
water in the level hose, etc.
Recommended actions:
1. Check in the service program that the level control is working correctly.
2. Blow through the level hose and check that it is not blocked and does not contain any water.
3. Check drain for dirt.
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 machine 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.
