New to us house came with GE Profile GSD1150X70. Probably the original dishwasher, so I estimate it to be at least 15 years old.
When I run it, it looks like it fills up correctly, and then I can see that it appears to drain correctly into the sink when on the rinse cycle. So I guess that water seems to be entering and leaving ok. The problem is that a lot of the dishes, especially on the top rack, seem to be coated with a lot of soap specs and residue.
I have cleaned out the drain and float switch so far. Hot water going in from the hot water heater is 120+ F.
Maybe the spray arms are clogged? How do I test that?
What is usually the cause for soapy dishes?
Thanks for any help. Trying to make this one last for a few more years until the kitchen remodel.
Remove the bottom panel and check the drain solenoid on the left side on the pump. The plunger should easy go down and return back under the spring power.
Open the door during the wash cycle and check the water level inside.

Gene, thanks for the reply. Do you have any tips on how to remove the lower wash arms? I tried twisting the housing both clockwise and counter clockwise and it wouldn’t budge. Are there any special tools I should use to remove this? I have attached some pics of the lower wash arms and the wash cycle water level. I hope this helps. photo 1-3.JPG (112.5 KB) photo 2-3.JPG (123.3 KB) photo 3-2.JPG (124.4 KB)
Start the normal cycle with no dishes and soap. Let the dishwasher fill up with water (2-4 minutes). Open the door, pour a gallon of white vinegar into the dishwasher and let it sit there overnight, then finish the cycle.
Avoid to use any gel detergents. I would recommend the tablets.
If the holes in the wash arm are not clogged then there is nothing wrong with it.
Remove the sump cover and sump cap (#506 & #508 on the diagram). Put your fingers inside the intake and check for any foreign objects (plastic, tooth pick, etc).
I checked the sump pump again and it is indeed clear.
However, there is a puddle of water in the sump pump. I don’t know if that is normal? Also, you can see dirt debris at the bottom of the dishwasher.
As I said earlier, I can see the water emptying into the garbage disposal when it is rinsing.
I have attached a photo of the upper arm, which looks strange to me because there is only a single hole on each end. I also attached a photo of the bottom of the dishwasher with the sump pump off. photo 2(2).jpg (17.9 KB) photo 1(2).jpg (22.3 KB)
It looks to me like there is not enough pressure during the wash and I don’t think it is connected to the upper spray arm. Most of water to the upper dish rack comes through the pop up tower which is a part of the lower spray arm. It needs a sufficient pressure to come up and distribute water.
One more part you may want to check is the piston & nut assembly (#564 on the diagram). You have to remove the filter frame (#543) to access the piston & nut. Then just unscrew it. Make sure there is no any foreign objects inside the valve body.
The piston was corroded shut with calcium deposits. I cleaned it all out and the dishes are now being cleaned much better! I had originally taken the filter screen off and had cleaned out all the debris under the screen but didn’t even know that there was a piston in there since it was covered in so much crud.
Thanks for your help Gene! You have made my wife happy!
