HDA479M-03 Hotpoint Dishwasher - Instructions

Since the pump and the motor was a single unit, I removed the assembly by disconnecting the electrical plugs and drainage connections. This was a very simple installation. I reversed the above steps, reinstalled the dishwasher and all worked out well.

The motor seized up on my 1990 GE Dishwasher
Repair would cost 360. Replacement about 600
I ordered the motor and pump from PartSelect for 137..44
Remover the under counter washer (it‘s very light) and removed the water and drain line and disconnected the power. Turned the washer on it’s top to access the motor and pump and removed the electrical plug in lines, and the clamps holding the pump on to the connections. Replaced it with the new motor and pump, reconnected the electrical plug ins, added an adapter hose part, tightened the original clamps then reconnected the water, drain and electrical connections and reinstalled the washer. All in about an hour, The only glitch was the grounding screw for the ground wire on the motor. The screw was too long to tighten. Substituted the original shorter ground screw from the old motor, and that worked fine. Only used 4 parts from the large assortment of parts supplied.
Immediately ran the washer through a cycle, all worked perfectly.

I had hoped to be able to do the entire replacement at the floor level through the front panel without moving the dishwasher out of the cabinet. That turned out to be impossible because two of the machine screws holding in the old pump rusted and would not budge.
I did however manage to do the replacement by moving the dishwasher only 16 to 18" out of the cabinet so that I could work on more than one side. A word of advice: Once the pump is disconnected get it out of the house as soon as possible. It will continue to leak on your floor otherwise. No point in getting your pants, shirt and tools all wet.
The best part of this replacement came when I buttoned the whole thing back-up and ran it. This new pump was significantly less noisy than the old one making it possible to stay in the kitchen and actually have a conversation with someone. (My dog no longer leaves either.)
Would I do it again....you bet!

First I removed the dishwasher from under the counter. I turned it onto it's side so I had access to the motor and pump underneath. I determined which version of the old pump I had. I removed the old part and easily installed the new motor/pump following the directions. It took a little while for the water to begin flowing when I started it back up. Eventually it did get going.

The repair went smoothly. There were actually instructions included with the parts, so that was nice. The only "gotcha" I found was that . . . after you take off the old food-chopper, you have unscrew the old impeller from the motor shaft. This was a bit difficult and you'll want some good pliers to do it. Don't worry about stripping where the food chopper screwed on-to, that part is attached to the impeller and there is a new one on the new impeller. When I re-installed everything onto the dishwasher, it rattled the first couple of times while the wear-ring was finding it's seat. Don't worry, that's normal. It went away by the third wash. I think I still have a small crack in the pump housing, though. The pump housing is two halves of molded plastic fused together along a seam, and I think the seam is starting to leak. It's about one drop every 45 seconds. I'm thinking JB Weld will fix it.

Once i had the dishwasher removed everything went as the instructions indicated except for the overflow switch.I removed the switch from the old bracket which is not required,just install the switch assy. to the new bracket and proceed as instructed. the total repair shouldn't take more than 1 hour if you don't make the mistake i made.I AM VERY SATISFIED WITH PRODUCT.
I HAD NEXT DAY DELIVERY AT REGULAR POSTAGE CHARGE.

I pulled the dishwasher out and detached the drain hose. I attached the new drain hose after cleaning out the connection to the garbage disposal.

Now my dishwasher doesn't stink anymore!

Old cap was already off and had string on it. Cut the string. Placed end cap over. Used needle nose pliers to open metal rail a little and put in new cap. Locked right in. That was easy. Thanks again.

Dismantled spray arm by hand nd twisted in the new plastic ring.

This website was able to find a part very quickly and priced very reasonably. Local parts department had quoted double the price and double the time.

After disconnecting the supply and drain hoses I unscrewed the security screws and slid the unit out of it's space under the counter. I tipped the machine about 30-45 degrees to one side and examined the underside. I noticed a solenoid that appeared to control a valve leading to the drain tube. I cycled the washer through a wash cycle and noticed that the solenoid never activated. I removed the solenoid and found it filled with debris. I cleaned it out and reinstalled it, but it still did not function. I ordered the part from PartSelect.com because they had the clearest description of the part I needed. Delivery was quick and installation took only a few minutes. After hooking everything back up and sliding the machine back in place, it works like new.

Once the new motor and pump kit arrived. I removed the dishwasher, turned it upside down and replaced the motor and pump with the new one per the directions. Difficulty came in feeding the electrical wire/plug back through the cabinets. Once done, turned on the dishwasher, filled the tub, then manually moved the dial to drian. The water still would not drain from the tub. I searched further for the problem. Here it is; Found the air gap tube was plugged with food. Once I removed, cleaned and reinstalled the air gap, the tub drained fast and everything works great. So, I hope you folks put this up in your troubleshooting section for others to check before buying a pump and motor kit. If you had, I would have been able to check out the air gap, clean it out first before spending $140.00 for a pump and motor kit I didn't need. Anyway, lessons learned..Jeff

I simply removed the front toe kick panels.
The solonoid is staring you in the face.
I removed the small nuts on back side of the solonoid bracket and removed the retaining clip and springs.
I installed the new solonoid and was very surprised how easy it was.

I DID turn the power OFF at the breaker panel prior to starting the repair.

Disconnect water line and screws (2) holding dishwasher under cabinet, and clamp for wastewater line. Pulled dishwasher out, turned on its side, and removed pump. Disassembled pump per instructions (great instructions) and installed new parts. Reversed to reassemble and except for a loose clamp that leaked (I tightened) it went well. Just under 1 hour.

Unplugged unit, unscrewed screws on top of dishwasher attached to countertop, undid water supply and drain hose that goes into tee with garbage disposal. Using crescent wrench turned front leveling screws up all the way and slid/rocked dishwasher out from under the counter - I had no problem leaving back leveling screws down. Turned dishwasher over on some towels (it WILL leak some water so spread out some towels!) so it was oriented like the directions that came with pump and motor. The directions were good, although color or a picture might have been more helpful. CHECK the new pump/ motor unit CAREFULLY for any loose debris from packing etc. I had a small piece of plastic that was in the top of the motor that goes in the dishwasher bottom that rattled around after I installed everything and put it back. I was able to get to it from the drain assembly in the tub but it made a heck of a racket at first. All in all, I had a great experience. I'm glad I ordered the pump and motor even though I only thought I needed the drain solenoid because when I took the old unit out, the prop on the old impeller was almost gone. Easy to order, good customer service (I called with a question and talked to a wonderful customer service representative!), good directions and easy to do. I'd say a 4 out of 10 in terms of difficulty. Thanks PartSelect!
