There was a number of posts last winter on this same subject, seems like new owners an old ones ask the
same question alike

www.kz-rv.com/owners-manuals/images/2017-KZ-RV-Durango-Owners-Manual.pdfpages 57 an 58, page 87 for water heater but it dozen't cover the dishwasher
Link to page for PDF for Frigidaire dishwasher, only short statement about winterizing ...
www.searspartsdirect.com/partsdirect/user-manuals/ffbd1821mb0a-frigidaire-parts-manualHere is what I have found an read about Preparing the Dishwasher for winterizing, there may be other ways of
doing such but I believe this is an ok way to do such ...
Before winterizing the dishwasher, you must prepare it by taking out any dishes. Also remove the silverware basket and
the wire racks if these are removable. If there is any food debris remaining in the dishwasher, clean it out with a sponge
or run an empty sanitizing cycle. Once no food debris remains, dry the inside of the dishwasher using a dishcloth, paying
special attention to the bottom of the washer and the container for detergent and rinse aid.
Water Supply
After the inside of your dishwasher is dry, an after you have run antifreeze thought-out your trailer you will need to make
sure that antifreeze is coming out of the
kitchen faucets which indicates there has been antifreeze sent to the intake lines
of the dishwasher ...
After making sure that you your plumbing thought-out your RV has antifreeze, pour a third to a half of a gallon of pink
nontoxic antifreeze into the dishwasher's basin. Turn on the dishwasher and start a short wash cycle. The antifreeze will
cycle into the tubes of the dishwasher. Turn off the dishwasher before the rinse phase of the cycle. The antifreeze will
remain inside the dishwasher throughout the winter and prevent its pipes from freezing. Put a sign on the dishwasher
indicating that there is antifreeze in the system to warn anyone who may attempt to use it.
After Winter
After winter is over and the risk of frozen pipes has passed, you will need to flush the antifreeze from the dishwasher.
Turn the water supply on by turning the knob on the water main to the left. Run at least three cycles to rinse the antifreeze
from the dishwasher's tubes and plumbing. Although it is nontoxic, you do not want to ingest any antifreeze or eat food
prepared on dishes coated with the substance.
Hope this helps
