Question and Answers


frigidaire dishwash model fdbb2840ec0 making loud whinning noise when washing


From the description you give I suspect the problem is with the motor.

The image below will show you how to remove the spray arm and filter screens to access the wash impeller.

Remember to turn the power to the dishwasher off first.

If there are no obstructions in the sump then the noise is likely from the motor. The entire sump assembly can be removed for better access.

I hope this information helps you to resolve this problem. You can submit another question with any additional details for further assistance.
