E20 fault code Zanussi ZWF1640W?

The manual says this is due to a blockage. Check your hoses, make sure they have not been squashed / blocked. If they are OK, check the filter at the front of the machine, it's under the flap. Careful, when you open the cap a lot of water will leak out, so be prepared with a tray or something. Losen the cap, let some water drain then empty the tray, keep going then eventually pull out the filter. Clean it out completely and refit. Test the machine, it should work ok. Worked for me.
