Eduardo B Weston , FL April 05, 2015 Just moved to new house and the pressure tower of the dishwasher was missing alltogether After a little research on internet I found out the part was missing. (By placing a couple of cups facing up on top rack, I noticed water was not filling them!) also read about using a cup of vinegar every so often (3-4 times a year depending on water hardness in your area) to get rid of the hard water stains. The part was all that the washer needed. works like a charm now. Thanks!. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
