Morgan L Cumming , GA August 19, 2014 Appliance: Model MDBH940AWW (DISHWASHER) Rinse agent reservoir was leaking unit wouldn't hold liquid… just ran out as you filled it Ordered the part. Arrived the next day. Took the eleven screws off the door exposing the back of the Soap/Rinse Aid dispenser. Six screws hold it on the inside of the door. Popped off easily. There is a plug that runs from the timer to the dispenser…it's a pain to get off. Use a flat head screw driver. Screwed the new unit in place. Plugged it in. Put the door back together. I accidentally caught the door catch in the door and screwed it together seizing it...so I had to take the top screws off again….release the door catch and screw it back together. Whole deal took 20 minutes even with the dog helping me the whole time. Save the $100 service call. Easy fix.
