What does a D5 error message mean during the deliming cycle? The dishwasher seems to work okay when using normally. The delime message is on and I get to the part that say add delimer and it gives an D5 message. I shut down and it does it again (about 5 times so far) I can not find anything about what to do for D5. (I am in a high school and it has been shut down for the summer.)
