Drainage Hose May be Blocked or Kinked

If your drainage hose is blocked or kinked, it can cause your washing machine not to drain correctly. These drainage problems can be caused by obstructions like dirt, lint, or small objects. Here is how to resolve the issue.

Clean the filters in the water supply hose.
Attention: The leaking water may be very hot with a risk of scalding.
Set program to OFF.
Pull out the main plug.
Check whether the drainage hose has been installed without kinks.
Loosen the hose clip on the siphon and carefully remove drainage hose and any residual water.
Clean drainage hose and siphon spigot.
Hold drainage hose in a bucket and select the DRAIN program.
Connect drainage hose to the siphon and check for leaks.

Pump May be Blocked or Need to be Cleaned

Another common cause for washing machine drainage issues is having a pump that is blocked. Here is how to clean the pump and resolve the problem.

Clean the pump.
Attention: The leaking water may be very hot with a risk of scalding.
Set program to OFF.
Pull out the main plug.
Open and remove service flap.
Drain any water through the drainage hose by slowly removing the pump cover.
Clean the interior, pump cover thread and pump housing. The impeller wheel of the pump must be able to turn.
Re-insert the pump cover and screw on firmly.
To check for leaks, pour 1 quart (1 liter) of water into the detergent dispenser. Check for leaks and then start the DRAIN program.
