Had a problem with washer not spinning all the water out. Did an extra spin and drain cycle on a few different loads. Eventually the washer was left with water left in the tub. I've checked for obstructions and found a couple Bobby pins. Removed those and tried again. Went through all the cycles and when timer was down to one minute, it went back to 14 minutes and never heard any water drain. I then did functions test and received errors f9 e1, f7 e7, f0 e2, f0 e5. I conducted the continuity tests for the drain pump and all tests came back normal. When I did the manual tests and tested the drain, I could here something turn on, but nothing happened or drained. I don't see anything clogged. I replaced the actuator thinking that was why clothes were still ending up wet. It says next thing is to replace main control board. I'm not wanting to spend over $300 for that part, so I was wondering if it could be something else. Is it sure it's not the drain pump?
