When the dishwasher runs the knob stops moving after the rinse position and does not continue to the off position.
Answer Hello Frank. You need to check and see if the heating circuit on the unit is good. If so, and the timer stops and does not advance, you will need to replace the timer on the unit.
Looking for a replacement knob. Original part number is wd9x339.
Answer Hello Scot! Unfortunately, the timer knob WD9X339 has been discontinued with no further replacements or cross references available and our company is unaware of any other available sources. Sorry about that!
