Fault

Cause and troubleshooting

Heavy foam build-up

Detergent dosage is too high.

Immediate measure: Mix one tablespoon of fabric
softener with 0.5 litres of water and pour the mix-
ture into the compartment for manual dosing (not
for outdoor clothing, sportswear or items stuffed
with down).

If intelligent dosing is activated, reduce the basic
dosage → 

Page 36

.

If you dose manually, reduce the amount of deter-
gent for the next washing cycle with the same load.

 is activated.

Select the programmes that are suitable for the
type of fabric.

Unbalance load detection system is using a reduced
spin speed to eliminate an unbalance.

Redistribute the laundry in the drum.

Note: 

Where possible, mix large and small items in

the drum. Different sized items of laundry distribute
themselves better during the spin cycle.

Start the 

Spin

 programme.

The spin programme
does not start.

Drain pipe or water outlet hose is blocked.

Clean the drain pipe and the water outlet hose.

Drain pipe or water drain hose is caught or jammed.

Ensure that the drain pipe and water drain hose are
not kinked or trapped.

The unbalanced load detection system has interrupted
the spin cycle because the laundry is unevenly distrib-
uted.

Redistribute the laundry in the drum.
