Can I run plastic plates through a high temp dishwasher?

I purchased a Hobart High Temperature Dishwasher, and then one of my employees asked me this question and I didn’t know the answer. We use melamine plates and plastic pepsi cups, will it melt these in the dishwasher at all, or will they be okay?

Anybody have experience with this? Thanks.

Melamine’s melting point is 662°F. The plastic glasses will be fine too. High temp dishwasher just means 180°F.
