You all would have to jinx our DW by talking about these too much in this thread, wouldn't you?
This morning after breakfast we started up the DW full load. We selected Normal Wash with Hi Temp wash option. I sat down at the kitchen table to work on some paperwork. After about 30 minutes or so of running, I noticed that the DW never went into drain mode after the pre-rinse mode. Upon closer examination it seemed like the DW just filled up for the pre-rinse, then continued right into wash mode without an intermediate drain. So I let it go. 75 minutes later it was still washing away without ever draining the wash water. Finally at 35 minutes of time remaining the DW finally went into drain mode and then immediately into heated dry mode. So it appears this damn thing has been washing buy not rinsing. Since we run it at night I wonder how long we have been eating off of dishes, etc. that still have detergent residue on them?
So I tried the "Rinse Only" option on the DW. It filled, rinsed the dishes, then drained and the machine switched off.
