Winterizing dishwasher

OK it’s the time of year for us to start thinking about winterizing the trailer. We have a builtin dishwasher the problem is there anything special you have to do
winterize? Don’t want any burst lines next spring.Do you need to run it through a wash cycle with antifreezeThanks

Check with the manufacture as the instructions are probably very specific. Our Splendide cloths washer is quite specific about winterizing. A busted pipe would be a drag for sure.
