Well, not sure what causes this problem, but we have pipes in our wall in our living room that vibrate and make a HORRIBLE sound---it only happens when we run the dishwasher in the kitchen. We can run the sink faucet, the washer which is in a room off the kitchen, both bathroom faucets, but only happens with the dishwasher. Someone suggested there is a simple fix possibly of just replacing the dishwasher, which I will say is now 20 years old almost. Can you advise? Not trying to get you guys here, just trying to get a little advice before contacting repairman and I have watched you before and you guys usually really know your stuff....if it is dishwasher, which it sounds like to me...easy fix
