GLD4450NC General Electric Dishwasher - Instructions

Replaced the plastic piece. Simple

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

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

just slid the new rack into 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.

Took the screws out of the inner panel to open it and expose the latch area. Found the door spring stuck to the insulation so we saved it. Used the part's list picture to figure out how to put the latch parts together (wish the picture was better). Reattached the inner panel. The latch works better now than when it was new....which makes us wonder.

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.

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.

Replaced keypad electronics PC boards.

Just put lids in place. Took about 3 minutes.

It was an install. My problem is that the drain tube is not standard to other dishwashers,so I could not get it at either of the local home improvement centers. The good news is that it is larger than the standard, and offers better discharge.

Dishwasher was not filling with water so I assumed the Water Inlet Valve was the problem. I replace the valve but still had the same problem. Studying everything I noticed another problem. The Drain Solenoid which I had replaced 9 months earlier was closed. The plunger was in the down position but must be in up position while washer is filling.
Water was pumped out as soon as it came in. I removed the Drain Solenoid and found the plunger securly stuck inside the plastic cylinder. I forcefully removed it. I knew the solenoid was probably OK because it jerked during the drain cycle. I put emery cloth around a dowel rod and sanded inside the plastic cylinder until plunger moved freely. I smoothed inside with wet or dry sandpaper. After re-installing the solenoid the dishwasher works great. My only explanation is the solenoid has a design flaw and that heat from the solinoid must expand the plastic inward over time.

For those of you that have this problem, please note that there may be three arms to your dishwasher, not just two. I also recommend calling this company to make sure you get the right part...there was no picture for the parts I needed.

Took the old ones off and put the new ones in.

My water has a lot of calcium and the spray arms clog.
Second time in 3 years

problem solved..thanks
