Cleaning the moisture sensors
Occasionally the moisture sensors have to be cleaned 
because a fine layer of transparent buildup is deposited 
on the sensors.
To clean the moisture sensors:
1.
Open the door.

The deposit on the sensors can easily be removed by 
wiping the sensors (the two bars next to the lint filter) 
with a cloth and a little white vinegar.
NOTICE:  Use white vinegar only!
Clean the moisture sensors once a month.
Cleaning the lint filter area
Over time, fluff from the drying process collects in the lint 
filter area.
This fluff can be easily removed using your vacuum 
cleaner, at least once a month.

may be kinked or bent, and/or the drain hose connection 
conditions. 
NOTICE:  If Check drain indicator still lights up after the 
maintenance, you should contact customer service or 
your local dealer.
