When you’re prepping for your vacation, your dishwasher may be the last thing on your mind. Running it one last time is a start, but here are some things to add to the to-do list.

For short-term vacations — a few days to a month — run the dishwasher one last time, then remove all the dishes and food debris from the spray nozzles or the filter at the bottom.

Avoid using Drano or other harsh chemicals to mitigate any clogging issues. Run a cleaning cycle with the dishwasher empty, as they require this step to prolong their efficacy.

A standard dishwasher tab or detergent will suffice for the cycle. If your dishwasher lacks a self-cleaning cycle, add a cup of white vinegar to the bottom and run it on high heat.

Lastly, prop the door open before you leave to allow any excess moisture to evaporate while you’re gone. This will also prevent mold and mildew from growing in your dishwasher.

For long-term vacations, you’ll want to also switch off electricity and water to your dishwasher, especially during colder months to prevent freezing water lines from bursting.

Not only can burst water lines damage your appliance and flood your kitchen, but many dishwasher brands also will not cover damage in this manner through their warranties.
