ACTION
Turn the machine OFF. Remove the
overflow pipe and drain the unit
completely (see page 12). Once
drained, clean wash tank and filters.
Replace all parts removed for
cleaning. Close door, turn the machine
ON and let fill.
Overflow pipe should drop straight

force.
Turn the machine OFF. Remove the
overflow pipe and drain the unit
completely (see page 12). Once
drained, pour hot water over air-trap.
Close door, turn the machine ON and
let fill.
If the water pressure above 3 BAR, a
Pressure Reducing Valve must be
installed (see page 8).
Clean the air trap by pouring water
over it.
The unit requires a minimum incoming
water pressure of 1 BAR. Check that
shut-offt valve fully opened. If
incoming pressure is still low, a
pressure-booster pump to increase the
water pressure may be required.
Remove and reposition the overflow
pipe.
Verify the breaker and all electrical
connections.
Verify that the water supply is turned
on.
Reduce the amount of detergent.
Drain the unit, refill and do a wash
cycle. If the squealing continues, call
