QUESTION FROM rbyford
QUESTION from rbyford on 3/16/2008:
When I run our dishwasher I hear a high-pitched buzzing sound while it's running. Also, the soap dispenser doesn't seem to be working right and the dishes are not getting clean. It's in good shape inside but is 13 years old.
ANSWER FROM HOME-WIZARD
It sounds like you dishwasher has some debris caught in the pump assembly. This could explain both the high-pitched noise and your unit's poor cleaning performance.
Depending on your particular model, you (or a trained technician would have to pull out the dishwasher from its installation and disassemble the lower spray arm section to check for debris in the pump.
Hope this is helpful.
