Description
The level control is a pressure guard which controls
different pressures, i.e. water levels, independent of
each other. The level control has two filling levels and
a third level which blocks the spin cycle so that it
cannot start while there is water in the drum. The
terminal configuration is illustrated in the adjacent
figures.
Control instructions
All level controls for the different machines are set by
the factory. These settings should not normally be
changed. For this reason, the level controls are sealed
with locking varnish.
Caution! The machine's guarantee ceases to be
valid if any adjustment is made to the level
control.
In special cases it is possible to change the break and/
or make level – but only within a limited range. This is
because each break level requires a special set of
pressure springs.
Control of water levels
•
Start the machine and select a standard program.
Check the low level during pre-wash or main wash,
and high level during rinse. Fast forward with the
start button. Check that the levels agree with the
illustrations.
Action in the event of overfilling
•
Check the hole in the nipple on the underside of the
level control. Clean as required. Note that the hole
has a restrictor which must not be enlarged.
•
Check that the hose to the drain is not blocked.
Clean as required. Clear the hose with compressed
air and without water in the machine.
•
Check that there are no holes in the hose caused
by abrasion. This may happen occasionally if the
hose lies against the drive wheel.
•
Overfilling can also result from burnt contacts.
Replace the level control if this is the case.
