The rinse agent dispenser must be clogged as nothing is coming out during wash cycles. I bought the house with this dishwasher. To fill it I had to use boiling hot water to clean out the hole to allow the rinse agent into the reservoir but a month later it is still 100% full.
For model number MDB7749SBB2
Hello Gina, thank you for your question. According to our research, if the dispenser is full of soap but does not dispense soap, there could be several problems. Firstly, check to make sure you do not have a clogged dispenser. If you know the dispenser is not clogged with solidified soap, unscrew the pump and make sure the tubes are all attached properly. Also, check to make sure the pump is primed. You can prime the pump by pressing it several times to get the soap into the tubes. Check for air bubbles in the line. You can get the air bubbles out by pressing and releasing the pump and discarding excess soap. If the dispenser still does not dispense soap, there may be a crack in the tube, and the pump will need to be replaced. We would recommend checking the following parts to fix the issue: detergent dispenser assembly, part number PS11773088, and electronic control board, part number PS8260218. We hope this solves your problem!
Pulled dishwasher from under counter, attached link to spring, hooked spring back into frame/chassis, threaded link through pulleys, attached other end of link onto door, reinstalled dishwasher under counter. All's well. Note-I purchased an extra link anticipating that the other one will fail. They're cheap enough.
Caviat: The actual repair is less than 15 minutes, but I spent a lot of time playing with it before I figured out it was that easy and fast. You don't need to remove the dishwasher from the counter to do this. And it will probably help to look at the new part closely so you can understand where the retainer clip is to press it and release the old pump.
First remove the water from the dishwasher pan that would not drain with a wet/dry vac. Otherwise the water will all drain on the floor when you remove the pump. Then remove the two screws on the kickplate on the front of the unit below the door. Remove the kickplate/maintainence access cover. The drain pump is on the right about 8 inches in. Using two hands you grasp the drain pump with your right hand and use the left hand to push the retaining clip down. Then the drain pump will rotate 1/4 turn counterclockwise and can be removed without pulling the dishwasher out. There is likely to be some water leak out that was traped in the pump housing that you can not reach with the vac. Disconnect the wire. Connect the wire to the new pump, put it in place and 1/4 turn clockwise to install it. Replace the kickplate and you're done.
Rather than remove the pump assembly - as an earlier post had done - I pulled the entire dishwasher out and laid it down on the floor. This allowed easy, direct access to the motor (that was the hard, messy part). From this point it was easy. Unplug the wiring, remove the retaining bolt, rotate the motor off the mounting brackets and pull it out. Then put the new one in. That was the easy part (about 15 minutes). The entire job took 2-and-a-half hours, most of which was taken in disconnecting, cleaning up and reconnecting the dishwasher. It's much quieter now.
