HDA479M-02 Hotpoint Dishwasher - Instructions

I had never done work on my dishwasher - I was a rookie in this area. Turns out the work itself was quite simple. Pulled the dishwasher out, turned it over, and was able to easily replace the motor and pump assembly. The drain tube was also an easy replace. A couple key notes:

1. I also purchased a new drain solenoid and impeller kit. Note that both of these items are already included in the Motor and Pump kit replacement. There is no need to by both, now I have extras.

2. The end of the drain tube has to be trimmed if you are routing the drain tube to an air gap mounted on your kitchen sink. You have to cut the large diameter end of the tube to get to the narrow portion that will fit on your air gap.

3. The first cycle you run with the new motor/pump assembly is noisy. When you first fire it up the components in the pump are all dry, and they squeal until the water gets to them. I initially thought I had done something wrong, but once the water started flowing all the peculiar sounds cleared up.

1. Remove lower cover skirt.
2. Shut of water at undersink valve.
3. Unplug power cord or turn off circuit breaker.
4. Disconnect water supply line from fill valve.
5. Unplug the electrical connector from the valve.
6. Remove the 2 valve mounting bracket screws.
7. With loose valve in hand, rotate to gain access to allow release of outlet hose clamp for hose removal.
8. Remove brass fitting from old valve and install on new valve. Use teflon tape on the pipe threads only.

Install new valve by reversing the procedure.

The most difficult part was removing the dishwasher from below the counter. Once that was complete, I simply turned the washer onto it's front surface to access the pump easier. Simply disconnected the electrical connectors, loosened the three hose clamps holding the hoses to the pump. Lastly removed a stiff arm bracket holding the pump. Reversed the order to install the new one using a longer bracket provided with the new unit. Hooked up the electrical connections last and slid the washer back in place. The washer runs like new now and is not making noise. The replacement part was a perfect match.

took dishwasher out- put on table to work on-removed wire brace- disconected drain outlet- disconnected top drive seal- removed wire clip connector- removed motor unit----------------
installed new motor/drain unit--used new longer wire brac used adapter to connect electical leads-
tightened clamps and bingo it worked and didnt' leak. good job on the supplying of all the necessary adapers.

Did the install a few days ago 4.25.11 and all went smoothly. The instructions that came with the kit were very straightforward and the diagrams were extremely helpful in locating brackets/hoses/connections. My dad thought he would just get down there and do it, but wasn't sure what to do. Using the directions with the kit, I had the motor and pump off in under 5 minutes. FOLLOW THE DIRECTIONS WITH THE KIT!

Some things to note:
- Get some towels/cups/bowls, we had some water leaking from the dishwasher and hoses.
- Be careful removing the dishwasher from the counters, go slow.


1. Shut off electricity
2. Shut off water. I just shut closed the line that went directly to the dishwasher.
3. Removed screws from bottom panel to expose motor and pump assembly.
4. Removed screws securing the dishwasher to the counters.
5. Slowly slid dishwasher from counter and rotated so door was facing the ground carefully to ensure wires/hoses were not pulled or crushed.
6. Removed screw from bottom of motor that was secured to the hanger.
7. Removed ground screw from bottom of motor.
8. Removed all wired connections from the motor and pump.
9. Loosened hose clamp securing the drain line and removed from motor.
10. Loosened 2x hose clamps securing the motor and pump assembly to dishwasher.
11. Ensured everything was clear and disconnected, and slowly removed motor and pump assembly from dishwasher.
12. Test fit new motor and pump assembly.
13. Reconnected 2x connections to the motor and pump.
14. Secured the ground wire to the motor and pump.
15. Slid motor and pump onto dishwasher and secured the 2x hose clamps.
16. Secured screw from the hanger cable to the motor and pump.
17. Reconnected water line to motor and pump, and tightened hose clamp.
18. Ensured all connections were made, hose clamps were tightened, and there were no extra connections.
19. Rotated dishwasher back onto feet.
20. Slowly slid dishwasher back into counters ensuring no cables or hoses were kinked or crushed.
21. Restored electricity and water to dishwasher, and then performed a quick test of one cycle to check for leeks.
22. Secured bottom panel and dishwasher to counters.
23. Enjoyed having a working dishwasher again!

The hardest part was removing the dishwasher from under the counter and cleaning up the large amount of water that poured out when I turned the unit on its side.
The actual pump replacement was pretty easy except there were a lot of extra parts that were only needed for other brands or other models.
I might have tightened one of the large clamps too much as there was a very slight leak after I was done. One or two drops of water per cycle, which evaporates quickly and not worth taking apart again.
It was not hard but took longer than predicted.
Much better than buying a new dishwasher or paying the estimated $350 to an appliance repair company.

Rather than remove the dishwasher from the counter, I performed the repair inplace, which was much less work (although I did have to lay on the floor).
After turning off the power, I removed the two access panels at the bottom of the unit, disconnected the wiring from the pump and solenoid, loosened the drain hose fitting and drained most of the water out of the unit and into a shallow pan (the drain solenoid was stuck open, so this was pretty easy - otherwise, I still could have manually actuated the drain valve & solenoid to drain water through this hose).
There was alot of water in the unit and my pan overflowed a little. If I was doing this again, think I would have disconnected the drain hose from under the sink and drained out through that into a bucket (I could have controlled that flow better).
Once the water was out, there are just two hose clamps that hold the pump onto the unit (one on top and one in the back), and a stabilizer bar that connects the motor to the front frame. Removed these and the whole unit came right out.
The replacement pump & motor was exactly the same as the one that came out, so I didn't need any of the hose or wire adapters that came in the kit.
Reconnected the two pump connections, motor bracket and wiring, and the unit was good-to-go!

1. Remove access panel under door. 2.Shut off hot water.3. Shut off electric to washer.4. Disconnect water line from water inlet valve.5. Remove small outlet water line from valve. Replace valve & reconnect. OR !!! 1.Take solenoid valve & bracket off of original inlet valve 2. Pull out white plastic diaphragm cover. 3. Remove diaphragm & clean out water holes with a pin. 4. Reassemble valve. 5. Reinstall original water inlet valve & save $27.00

After removing the dish rack I unscrewed the center riser spray by turning it Clockwise and I removed the lower spray arm. I then removed the lower spray arm support using a phillips screw driver and replacer the worn water seal. I reversed the process and reassembled the sprayarm and center riser spray. Job completed!

I received my dishwasher as a hand me down, my Aunt never liked the way it cleaned. After it sitting for about 2 years i installed it in my house and found that it leaked all the time from where motor shaft went into the pump housing. After disassembling everything and scouring parts sites online, I found the parts, ordered them. 3 days later i had the parts, and the next day I had a fully functioning leak free dishwasher.

first, I removed the screws holding the dishwasher to the countertop.Then I removed the dishwasher from under the counter. I turned the dishwasher on it's back and loosened the three hose clamps securing the water connections to the pump assembly. I then removed the electrical plug to the motor and the screw holding the support rod to the motor. Then I worked the loosened water connections apart and removed the pump and motor assembly.
Then I removed the hose clamp and plug from one of the orifices on the new pump, and aligned all of the water connections and wiggled the new pump assembly into place. I tightened the hose clamps, Installed the new screw and support bar to the motor, and connected the electrical plug. I then turned the dishwasher upright, reconnected the power cord, water supply and drain lines and started a wash cycle to check the new system for leaks. I found that the extraneous drain solenoid that came attached to the new pump was loose and rattling, so I secured the solenoid shaft and linkage to the pump housing with electrical tape to stop the rattling.

Removed the dishwasher, turned it over, removed 3 hoses, 2 clamps, 2 wires and one support. Installed new pump and reconnected. Done!

Shut off circuit breaker to dishwasher and shut off valve to dishwasher under sink.Remove bottom access panel screws on both sides of panel. Remove both screws holding dishwasher to counter.Place old mattboard strips under legs to prevent scratching floor & slide out from under counter. Use a Shopvac to remove water and spillage. Have rags and paper towels handy. Carefully disconnect wires, drain hose and water line to free dishwasher. Fold old rug runner in half to place dishwasher on, turn on side and then gently upside down on rug to access motor. Remove butterfly clamps, hose clamps, electrical connections, and support bracket. remove old motor and pump and place in box to discard. Position replacement motor and pump according to diagrams. Reconnect all clips, hoses and connections. Since replacement motor and pump is smaller, use longer support bracket from adapter kit. Return dishwasher to upright position and reconnect wiring using wirenuts, drain hose and waterline. Reposition mattboard strips under legs and slide back into place. Attach screws to counter top. Turn on power, water and do a test run to check for leakage. Replace bottom access panel. Pat yourself on the back since you've saved yourself hundreds of dollars for a repair or replacement of your dishwasher.

I made this replacement more dificult because I removed the old motor/pump earlier. Should have done it at the time I installed the new unit to be sure all hoses where installed correctly. I hooked the drain hose to the wrong port and when I started the dishwasher I found my error. Once I corrected the problem and started it again - the wash and drain cycles were perfect and there were no leaks.
