OK and have you already cleaned the drain pump filter ?
If not then unplug the appliance and remove the bottom front flap.
Then rotate the drain pump filter anti clockwise to open.
Clean it completely and make sure it is not clogged.
With your fingers check if impellor rotates.
Then you will see a pull tab next to the filter, pull it to open the door.
Now, reconnect everything and plug it back.
Please try any program and let me know how it goes.
If you have any further questions, please do not hesitate to ask!
I hope you have a great day.
It has been my pleasure to assist you!
