11:29 WATER LEVEL LOW DLCU LEVEL HIGH
The DLCU on I/O type 10 contains a mechanical level guard which ensures that there is no
water in the machine when the lock opens. To ensure that the level guard functions correctly, the
mechanical level guard is compared with a nominal value generated by the level system, which
is compared with the electronic level sensor.
When the mechanical level monitor is switched off during draining, the water level in the drum must
be below the nominal value measured by the electronic level control.
Cause
• The level control can be damaged.
• Cross talk in the level control electrical system.
• Leakage in the level controls’ air hoses.
• Incorrect nominal value, possibly caused by a error in the electronic level control.
Action
• Check the level control function. (Switch-on level = 40 mm, switch-off level = 15 mm Wg).
• Check the cables and their connections. The voltage across the level controller should be 0 V
when the water level is < 15 mm Wg and 5 V when water level is > 40 mm Wg.
• Blow through the level hoses and check that they are not blocked and does not contain any water.
