The electronic unit  and drainage
and overflow protection
– Drainage protection
Any leaking water is collected in the
sump  in the base of the machine.
A float switch  closes the solenoid
valves , preventing any more water
from flowing into the machine and
water in the suds container is
pumped away.
– Overflow protection
If the water level exceeds a certain
level, the drain pump  switches in
and pumps the excess water away in
a controlled manner.
Should the water level rise repeatedly
in an uncontrolled way, the drain
pump  will switch on continuously,
the washing machine will indicate
that there is a fault and a tone will
sound.
Drain hose
The drain hose is protected by a ventila-
tion system which prevents the washing
machine from being emptied com-
pletely.
