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?
