GHDA486N10SS General Electric Dishwasher - Instructions

Followed instructions on how-to video on website on how to remove and replace lower spray arm.

Pulled old spray arm off and snapped new one on. Less than 3 minutes and works great. Dishes are cleaner now.

Repaired the soap dispenser.

Replaced lower spray arm

Very easy - remove the screws around the inside of the door. 6 screws and 2 plugs to remove the assembly. Just be careful not the strip the sheetmetal screws when putting it back together. No screwguns...

I measured the diameter of the working wheels from the existing ones, and located the parts I needed from the website. I order two packages, each containing the wheels and axles for the rack.
When delivered, I snapped the wheels onto the delivered axles. Then, I snapped the axels unto the bottom rack, at the correct place. I used a large pliers for leverage because the axel was a bit tight to just simply snap on.
The middle wheels are located just behind the front wheels, thereby offering support when the botton rack is pulled forward for loading. Likewise, they offer support when the rack is pushed back in place.

Ordered and replaced all three spray arms. The upper and middle spray arms were quickly replaced with a net-driver and are now working much better. The lower spray arm required no tool, just turn it CCW and lift it up. After replacement lower spray arm is still not moving at all. Maybe the lower spray arm washer is defective or the pump is just not putting out enough water. Will consider further repairs or replacement of the dish washer, it is 13 years old and used daily.

Just remove the lower basket from the machine and pull the old wheels off. Then snap on the new wheels on the pegs. The old style wheels snap in place without much force. The new wheels take much more force to install and lock onto the basket which keeps them from coming off when the basket is heavily loaded.

Just put lids in place. Took about 3 minutes.

Replaced the plastic piece. Simple

Very Easy! Lift old arm out and replaced it with the new one.

The most difficult part was removing the old wheels. The plastic coating on the rack had come off, leaving the metal exposed. The wheels had rusted on - that's why they wouldn't roll. Once we got them off with pliers, hammer, screwdriver and basically everything in the tool chest, we were home free. Installing the new wheels and axles was easy.

Replaced keypad electronics PC boards.

After removing the front panels, I removed two screws holding the valve in place. I turned off the water supply and removed the water line, unclipped the hose clamps and took the faulty valve out. I then reversed the above steps and turned the water back on. NO leak. Very easy to do andthe repair took ~20 minutes to complete.
