If you start a new programme, does the machine first of all pump all of the water out?
Check the drain hose where it connects to the house drains.
If it's onto a connection (normally under the sink), take the hose off and check both the hose and the connection for a blockage.
Let me know what you find.
OK, You'll need to cancel the existing programme and start a new one.
Does the drain pump run first?
Does it fill with water?
(keep the drain hose raised at least 3/4 the height of the machine).
Aim the hose into a bucket and cancel the programme.
Does it empty the water?
OK, unfortunately it's sounding like a faulty pump.
If the drain pump is running then it should pump out.
If the impellor is damaged, it won't pump.
You really need to be sure of what is running.
If it is the drain pump, then I'm afraid it sounds like you'll need to obtain and fit a new pump.
You're very welcome.
Good luck with the repair.
Hope this helped
