Fisher & Paykel Dishdrawer warning!

I've worked on a bunch over the last 20 years, and they have many issues, but the worse thing that can happen is something you'll never know about unless you pull that stainless filter plate off the bottom. Certain detergents cause a build up under there the attracts food stuff that rots or thick molds that grow. It's by far the grossest thing I've seen in a dishwasher (and I once found a dead mouse).

If you own one, do this immediately, and then again every few months: https://youtu.be/LCLKvzhvElk?si=swSYXkQ2cvuQmmDC

If you find gunk, scrap it up, then run several cleanings with something like Lemishine. Don't use any soap that creates suds.

Good luck!
