Spent two hours chasing a phantom noise on a Bosch dishwasher

Honestly, I feel a bit dumb about this one. Got a call for a loud grinding sound on a Bosch 800 series. Customer said it was awful during the drain cycle. I went straight for the drain pump, pulled it, checked for debris, nothing. Then I pulled the whole sump assembly, thinking maybe a broken impeller. Clean as a whistle. Took me a full two hours of disassembly before I finally ran a test cycle with the toe kick panel off. The noise was coming from a loose piece of trim on the customer's own cabinet, vibrating against the dishwasher frame at a certain frequency. Charged them my one hour minimum of $95, but I basically ate the other hour of my time. Ngl, it was a lesson in checking the simple, free stuff first. Anyone else ever get totally fooled by something that wasn't even the appliance?

That "checking the simple, free stuff first" lesson is a tough one. Do you have a go-to checklist now for weird noises before you start tearing things apart?

Yeah, @hernandez.miles, it's always the simple stuff. My dryer was making this awful grinding sound last month. I was ready to order a new drum bearing kit. Turns out my kid's pocket change had fallen out of his jeans and was just rattling around the lint trap. Felt pretty silly after taking the whole back panel off for nothing. Now I check pockets and the lint area first for any weird noises.
