Kirsty - There could be an item like a hair clip Jamming the pump impeller. Or then it can be only a blockage in the filter or in the waste pipe or if the waste is connected to your sink drain check that the blockage is not there - either in the end of the pipe or in the sink connection.

Try disconnecting at the sink, holding the waste pipe into a bucket see if it will pump out then. If it does then the problem lies in the sink plumbing - if not then it lies in the machine.

If the pump and filter and hoses are definitely clear you could have a Pump, PCB or wiring fault. Hope this helps.
