My filter was clogged with change and finish nails. After cleaning it out I was still getting SUDS followed by F05 messages. With the filter out (and power off) I could stick my finger into the hole toward the pump propeller and push it back about a quarter of an inch. The propeller had crept away from the body of the pump which misaligned it with the drain hole. I could see the water in the clear vertical drain tube trying to get to the top of the washer. It drained okay on the wash cycle but not on the drain cycle. I bought a new pump on eBay for $49 and was back in business.
