1. Ensure the drain hose is in the correct position

The drain hose should extend no more than 10 cm down into the drain. 

2. Ensure correct drain height.

The height of the drain must be no more than 100 cm and no less than 60 cm above the base of the machine or as shown in the user manual. 

3. Clean the pump and filter.

Clean the pump and fluff filter, including the pump blade (if the pump blade is visible, rotate it with a pencil and refit the filter). Then start a hot wash without adding any soap powder to clean out the drainage system.

If the pump blade was jammed the problem may be solved by switching off the power to the washing machine for about 1-2 hours and then starting a wash cycle again.

If the pump has been blocked, a bimetal fuse will switch off the pump. When the pump has cooled down, it should work normally.

4. Check for a blocked drain.

Check the hose connected to the sink trap,and check if the sink is draining normally to rule out blockage.

Check whether the drains are draining satisfactorily. Try a wash with the drain hose in a bowl or sink.  

5. Check the drainage hose for possible kinks or twists.

Kink or twist in the drain hose may prevent the water from flowing through the hose. You can check it behind the machine.

6. Use less soap powder.

When a lot of soap powder is used or a lot of foam is produced, the level system can get blocked by foam.

You can fix this by switching off the machine and shaking the drum forwards and backwards several times. Clean the drain pump/filter and then run a hot wash without any soap powder.
