For the first time this DW is making a loud whine sound. It has always been very quiet and this sound is loud enough that we can hear it "everywhere" in our condo. We even had to turn the TV up. We have had no problems with this unit until today, I checked to see if anything was blocked, etc. All looks fine the arms are going around, it seems to be working OK except for the loud whine.
Any help, please! Thank you
