Can I use my dishwasher solely for drying?
Absolutely!

Open the dishwasher.
Hand wash dishes.
Place wet, freshly washed items in the dishwasher racks.
Allow items to dry.

On a more serious note... Dishwashers are designed to wash dishes - it's right there in the name. There are some dishwashers that don't even have a &quot;dry cycle&quot;, they're designed to wash, then allow the items to drip dry.
You might, with enough time, find a dishwasher that has a &quot;dry only&quot; cycle, but they're probably few and far between.
That said, you may want to contact the manufacturer to see if there is a magical incantation of buttons you can push to get a &quot;dry only&quot; run, but I'd doubt it.
