Winterizing Reminder


Hi everyone.  If you have a residential refrigerator, there are a few extra things that need to be done when winterizing.  For details, please refer to our owner-written Residential Refrigerator Guide.

Also, if you have a dishwasher, don’t forget that it also needs to be winterized.  Here’s how:

  1. Winterize the rest of the coach first
  2. Set your air compressor to 40 psi.
  3. Press Power Button on Dishwasher to turn it on
  4. Set Program Cycle to Heavy (or any cycle)
  5. Shut Dishwasher door and dishwasher will start
  6. Dishwasher will call for water. Most of the water in the coach lines will be gone. A bit of residual water may enter the dishwasher along with compressed air during the beginning of the wash cycle. Allow it to run for up to 3 minutes until you hear the dishwasher drain pump start and then stop
  7. At the back of the dishwasher, place a towel below the drain line connection (lower left)
  8. Grab a shallow bowl and a small dish/hand towel. Place the towel in the cabinet below the drain
  9. Using hand-pressure only, remove the drain line and place the bowl below the drain to allow any water to be caught in it. Empty the bowl outside or in the toilet, then put it back in place under the drain. Leave the drain line disconnected

  10. Press Power Button on Dishwasher to turn it off
  11. Pour a cup of RV Antifreeze into the bottom center of the dishwasher
  12. Repeat steps 3 through 6 and step 10. About a cup of liquid should empty from the dishwasher into the bowl. Much of it will be antifreeze. Pour this down the toilet bowl

  13. Repeat steps 3 through 6 and step 10 again. This time, the liquid should be 100% antifreeze. Here again, pour that antifreeze into the toilet bowl
  14. Press Power Button on Dishwasher to turn it off
  15. Reconnect the drain line – hand tighten
