Error message EC03 appears on cotton cycle after 5 minutes into wash

I found the basic instructions that came with the washing machine and found that you need a screwdriver to undo a screw to remove the filter cover. I then gradually released the filter cover to empty the water out of the machine in small quantities into a shallow tray. I was then able to remove the filter and clear it of 2 x 20p pieces and a load of gunk. I then removed the 'washable' floormat from the drum as the rubber backing from the mat was crumbling and probably not helping the filter. Filter cleaned and cover screwed back in, mat in the bin, and everything working fine since.

I did try ringing the customer support number and after pressing loads of keys to select appropriate options; confirming my address, postcode, name, date of birth, email address, mothers maiden name, what the kids had for breakfast etc, I was allowed to ask how to get the filter cover off. Apparently this is a technical query and would involve arranging an engineer to call. I declined this very kind service option and opted for a screw driver, common sense and a positive attitude. Worked for me! No blood shed, a tiny bit of sweat whilst trying to get through on phone, and only tears of joy when I fixed it all by myself.
