no water in the machine when the door unlocks opens. To ensure that the DLCU level switch

sensor. At program start and program end, when the water level is below LEVEL EMPTY value,
a check is made to ensure that the mechanical level switch is not activated If it is activated, this
error code is shown.

Possible causes:
• The mechanical level control can be damaged.
• Mechanical level control is not connected or bad there is bad contact in the connector.
• Leakage or clogged level controls air hoses.
