Cleaning the drain

pump

This is necessary if the washing solution has not been

completely drained. The pump is blocked by either

loose debris or fluff which accumulates if fluff-giving

fabrics are washed.

Drain the water (Up to 20 litres. Have a suitable container ready.)

m Risk of scalding!

Allow the hot water to cool down beforehand. Keep

children and pets away.

■ Turn the programme selector to / Off.

■ Open service flap

■ Carefully unscrew the pump cap - do not remove it

completely - and let the water drain out into a shal-

low container (let the remainder drip onto a floor

cloth). Repeat the operation until there is no water

left in the machine.

■ Remove the pump cover.

■ Remove foreign objects/fluff from inside and clean

the interior. The pump impeller wheel must be able

to rotate.

Clean any residual lye or fluff from the thread of the

pump cover and pump housing.

■ Insert the pump cover and screw tight.
