MDB4709AWQ2 Maytag Dishwasher - Instructions

Checked grinder and cleaned it several times, adjusted blades. Dishes would be clean for approx. 6 cycles, then would not clean. Placed dishwasher on its front and removed the motor. Removed grinder and impeller which I found to be worn so that the blades would not turn on the grinder which caused it to collect food particles. The impeller locks in easily.

open dishwasher door, use torx socket and ratchet to remove 6 screws. Pull down wash options face, find the bi-metal fuse. Used the directions in the package to replace. popped old fuse out of electrical board, Cut 2 wires, stripped said wires, attached stripped wires in housing on new part, tightened the 2 screws where new wires attach, popped new fuse in electrical board. Reattached face. Very simple and easy to do. Did not fix the problem. Had to get the electrical board that the bi-metal fuse is snapped into. Very easy for someone that has worked on vehicles or electrical things before. If no experience, then I would say it is still easy as long as you follow the directions taht comes with the part. It has pictures as well.

I shut off the power to the dishwasher, then I removed the front panel under the door. On the right side just behind the electrical box there are two wires going up to the hi-limit thermostat, (you may need a small mirror to see it), remove one screw that is holding the thermostat bracket, unplug the wires from the old thermostat and install new one. Screw bracket and thermostat back to the underside of the dishwasher, reinstall the front panel, turn on the power, done.

removed both upper and lower racks. removed lower spray arm(left hand thread) removed "water delivry tube and upper spray arm. removed torx screws on pump cover. removed inner chopper cover. Chopper assy had come apart and was full of food crud. cleaned out and installed new chopper assy. kind of tricky don't force it. reassembled. tested OK.could tell sound of more forceful water pressure

First I unplugged the dishwasher.Then I removed 6 Torx screws, popped off cover, cut wires to old fuse, stripped wire, placed wires in new part, tightened screws, reassembled in reverse order, plugged unit back in and tested. WOO HOO!

I saved over $150.00 by doing it myself instead of having a repairman come out! That's 4 free fishing trips!

I released the heater element from the clips on the bottom of the waaher tub. I pulled the unit out from the wall and disconnected power. There are two slip on wire terminals on each end of the heater element accessible from the back that need to be removed. One of them was badly rusted from leaking water, which had caused the short, and had to be replaced. These terminals and the crimping tool to install them are available at any home center. I removed and discarded the old plastic nuts since one of them was damaged by arching from the short circuit. Moving around to the front of the dishwasher, I removed the old heater and installed the new one. I had ordered new rubber washers, but the new heater came with them already installed. Since one of the old ones failed and caused the leak, they are a good thing to keep around as spares anyway. I installed the new nuts and tightened them to enough to ensure that the washers made a good seal. I reconnected the wire terminals to the heater, reconnected power and moved the unit back into place. The circuit opening when the heater failed caused a "call for service" error and the controller would not allow the unit to run. You will know you have this by the "CLEAN" LED flashing seven times. Clear the diagnostics by pressing the buttons for "HEATED DRY", "NORMAL", "HEATED DRY", "NORMAL" and after the controller resets, the dishwaher is ready to run. It's worked like new ever since.

Turned off power, turned off water supply and diconnected, slid out dishwasher. Removed the spray wand and tilted dishwasher to access the two nuts and disconnet the wires. Removed the two nuts using a socket. Removed the old heating element and replaced with the new one secured with new nuts ( the old ones were fine but since I bought two new ones why not). Pluged the wires back up slid the dishwasher back in hooked up the water reinstalled the spray wand cut on the water and power. Good as new.

Removed the Bi-Metal fuse and ordered a new one and recerved it two days after ordering. Replaced it and it worked.

Removed dishwasher from under the counter and took it to my shop. With the washer on its side, I removed the motor, then the impeller and seal. I then disassembled the motor and replaced the front bearing(purchased separately). This required an arbor press. I then reassembled the motor and installed the new seal and impeller. Reassembled in reverse order. Reinstalled under the counter and made conections. Checked for leaks and proper operation.

Disconnected the power and hot water supply.
Removed mounting screws under the counter, and the lower panel screws to expose the leveling screws.
Backed the leveling screws up so that the unit would slide out more easily
Walked the unit out to where I could reach the back side.
Disconnected the two power wires from the heater coil (slide off)
Unscrewed the plastic nuts holding the heater in place and removed the heater coil.
Replaced the heater coil and nuts.
Reversed the process above to install.

I watched the instructional videos that showed how to replace the inlet fill hose/water inlet a couple of times. The repair was exactly as shown. No trouble at all.

I simply pulled out the old gasket and pushed the new one in with my fingers. I had to trim about an inch off the length with a utility knife. The seal is nice and tight now and we have no more water leakage.

Remove front door panel, replace B-metal fuse.

The upper spinner was laying in the top washer basket. I went online but no help was avaiable. Went to store where we purchased dishwasher and they gave me part number to order but not online I had to call to order. Part arrived in about three days. I took two screws loose on the top of dishwasher removed broke retainer to put new retainer in but I drop it into dishwasher so you have to me very careful
so I tried to order just the retainer but is not sold by it self. Had to order whole new kit. Other than that it is easy dishwasher runs like a new one.

The first thing I did to repair my diswasher was call a repair company. They wanted $175.00 just to look at it, so I scheduled an appointment. Then, I did an internet search for dishwasher repair. I learned about bi-metal fuses, and how to check them. I found my bi-metal fuse was bad, so I ordered a new one through parts select. My part arrived in two days. I installed it easily, and the dishwasher worked. Finally, I canceled the repair appointment.
