If this is your only front loader and you have two hookups:
First, I would follow the instructions for running your Duet through its cleaning cycle, with bleach. This will help keep any organisms from accumulating too much on the internal components. Wipe the boot dry, and any place that's accessible. Also, disassemble the detergent tray, then thoroughly clean those components. Keep the door open at all times. Now, set the Duet on the least used hookup and ONLY use it for bulky items that it can handle. Winter parkas, small comforters, pillows, that sort of stuff. The Duet is not going to reduce your water bill or save enough energy to matter anyway. In fact, mine uses MORE electricity and the same amount of water as my Frigidaire 1-18!
Meanwhile, save up for a Speed Queen top loader. When you get it, set it up as your DAILY DRIVER, and keep it within easy reach. You'll save a lot of strain on the Duet, and you'll be able to use it for what it does best: Thick, and puffy items that aren't too big. This will extend the life of your Duet significantly. Yes, you can make these machines last a while, but you really have to be vigilant and willing to spend a lot of time in their care and feeding.
