We bought a new 2017 bighorn with a stackable washer and dryer. Has worked beautifully last summer. Took RV into Camping World for some warranty work and it took them six months to complete a few issues. Of course the one year warranty expired while it sat on the lot. We picked it up this weekend and the first time I used the washer I got a F-05 error light. No place in the instruction book does it have a list of error codes. I finally found one on line. Says the drain is plugged, which could be correct as there is water in the tub and when I try to drain it it will not drain. Any suggestions and advice on this is GREATLY appreciated as we are two days into our summer trip.
