First thing to check is the drain hose where it connects to the house drains.
Ensure there is no blockage.
If OK You'll need to drain the appliance manually.
Put a shallow dish in front of the filter.
Slacken the filter a little and tighten it again when you need to empty the dish.
Once empty, unscrew the filter and take it out.
Remove any debris and check for debris in the pump, jamming the impellor.
Before refitting the filter, put the machine on a spin programme and look/listen at the open filter housing to see if the pump is running.
If it is, refit the filter and try the machine again.
Hope this helps
Let me know how it goes or if you need more help
