OK, thanks for that.
First, check the drain hose where it connects to the house drains.
If it's onto a connection, take the hose off and check the hose and the connection for a blockage.
If ok, you'll need to manually remove the water from the machine.
Take the plastic cover below the front panel off.
Put a shallow dish in front of the filter.
Slacken the filter a little to drain the water.
Tighten the filter to stop the water when you need to empty the container.
Once the machine is empty of water, take the filter out.
Clean out any debris in there.
Look into the filter housing and you'll see the pump impellor.
Ensure this can turn and isn't jammed by a small piece of debris.
Remove any laundry.
Put the machine on spin only.
Look into the open filter housing to see if the pump impellor is spinning.
If all ok, refit the filter and try the machine again.
Hope this helps
Let me know how it goes or if you need more help
