GHDA485N10CS General Electric Dishwasher - Instructions

I removed the plastic end caps by gently pushing and twisting them. Once the end caps were off the basket slid out. The old wheels were removed and the new ones clipped in very easily. I then slid the basket back into place and replaced the end caps. The most difficult part was removing the end caps. I was afraid that I would break them, but by being careful and not forcing the piece they easily came off.

Changed the main chip. the unit then started and continuously ran. Thought something was wrong with it. It is just a cycle of the dishwasher and when the pump quit running the dishwasher ran and operates. Saved me lots of money and time.

two screws, two minutes, all done

Replaced lower spray arm

Replaced keypad electronics PC boards.

Disconnected water, drain, electrical- remove dishwasher.
Place dishwasher on back removed part- replace with new part-reconnected and reinstalled.

Just put lids in place. Took about 3 minutes.

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

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.

Replaced the plastic piece. Simple

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...

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.

Checked availability of replacement machine and replacement parts online..in this process, I ran across a similar story by someone who fixed similar problem on a similar machine. Before removing the fill valve, I tried to confirm that it was defective my reading solenoid coil continuity. It looked ok so I could not use that info to confirm a bad fill valve, although that possibility was not eliminated. So I ordered a replacement fill valve, removed existing fill valve and took a long position on paper plates. On delivery of the valve, I found that its mounting bracket (which forms a part of the supply pressure boundary) had been redesigned to conform to a year-2000 redesign of the machine. Valve instructions allowed for this and provide for retention of mounting bracket from old valve for use on new valve. Instructions indicated the o ring from new valve (vs old) should be used in attaching the old bracket. I found that the o ring groove in the new valve was so deep that o-ring compression on reassembly was prevented. I went ahead and put together with new o-ring. When turned on supply pressure, it began leaking immediately, so I shut down, removed valve again. During this (2nd) reassembly, I stacked both o rings in same groove in order to get compression at all. Reinstalled valve w/ both o rings....no leaks and it works. I think valve design should be reviewed and depth of o ring groove reduced so only one o ring is needed.
