Without the information requested in my previous response, I can only give you a general answer however, I hope this helps.
These issues may occur if drain is clogged or if control is locked.
Please try this to solve the issue:
You will have to unplug the appliance and remove the bottom front flap.
Then keep some beach towels and shallow container under the filter.
Now, rotate the drain pump filter anti clockwise to open, clean it completely and make sure it is not clogged.
Also with your fingers check if impeller rotates, then reconnect everything and plug it back.
Then try any program and it should work however, if the issue appears again, then I am afraid, the drain pump and/or control board is faulty, and will need replacement.
If there is anything else I can help you with, please let me know.
