Our current sound Reading decibels for a CMA dishwasher eva2000 is 77 dB with a high pitch noise I replace the bearings in the motor and replace the spring seal in the pump, no cracking or broken impeller parts were found.

77 db doesn’t sound to bad.. A scale? Remember that hearing damage is time rated and a dishwasher only runs 5 to 6 times per hour for 30 to 60 seconds.in most kitchens. As for the high pitch, where does it seem to be coming from? You must have access to a sound meter, so set it for the high weighted scale,place a 6 inch plastic tube over the mic and it becomes directional. Now you can find the source. I use a ultrasonic leak detector for that, as the sqeal will go far above what we can normally hear. BTW, I am quite flamilar with hearing loss. I wear bi-lateral hearing aids and had a 80% loss on the upper end. Thank you Vietnam.

In my nineteen years of doing service work on commercial kitchen equipment, I have NEVER had anyone ask that question. So…of all the test equipment in my tool box(es), a noise level meter isn’t one of them. A mechanics stethoscope is the closest thing I’ve got.
I learned two things from researching your proposed question:
- The decibel level of a dish machine isn’t included in their spec sheets.
- There’s an APP for that (Who-da thunk?).
Sorry, but no help here.
