I have a frigidaire dishwasher only two years old. It has started to make more noise then usual when it is run. I am not sure but the noise sounds like a motor to me. I told my wife she should stop using it until we can figure out what is wrong.

How do I troubleshoot it to figure out what is wrong? It is Model number FDB1250REC2.

Thanks in advance.

How do I troubleshoot

You have to take it apart to see/hear where the problem is exactly. There is no trouble shoot guide for noise except for common mechanical sense.
