Karen asked me to help you out since we may have the same year/model. Given the relatively new age of your unit, I would suggest calling Mitch or Randy and ask them about FR replacing the seals for you. It would seem that they shouldn't have worn out so soon.
Get back to me if you want to discuss this. I'll fill you in where you may be able to get a better answer than I gave you.
