Hello,

I have a GE dishwasher, The Middle and Top spray arm are not spinning and the dishes are not getting clean properly. I have replaced the filter - 451. What could be the issue.

Check that there is not junk in the sump.
Be careful as there is often broken glass in the sump.
Also check that there is nothing wrapped around the chopper blade.

Check that to seal/connection for the center arm to the rear water supply conduit is OK.

Check that it is getting enough water.
Most units fill to just under the heating element.
You could add a quart or two of water after a fill.
Just be careful to not overfill the unit.
If the arms now spin I would say that is your problem.

The most likely cause is a partially clogged screen filter on the input side of the water valve.
Remove the valve from the unit and check/clean the screen filter.
Do not permanently remove it from the valve as it is there to keep crud out of the valve which could hold it open and cause a flood.

Thanks for the help, When i add more water the arm spin fine. If i am reading your msg correctly. You want me to remove the water inlet valve and check/clean the screen or is that a different part. Can you tell me which part to look for and how easy it is to remove that part.

thanks

The valve is Item 744 in Section2 which is mounted under the unit usually on the left hand side.

Shut the water off to the dishwasher.
Place a shallow pan under the valve.
Unscrew the inlet connector till it starts to drip.
When your pan is near full re-tighten the fitting (usually you can do this with just your fingers) just till the dripping stops.
Empty your pan and repeat.
Keep doing this till the inlet line is empty.
Then remove the valve from the unit.
And clean/check the inlet screen.

If the screen is clean then you probably need a new valve.

Always a good idea to shut power off to the unit.
Also have paper towels or regular towels just in case you have a spill.
If you have them handy, you probably will not have a spill. If you do not have them handy a major spill is almost guaranteed.

Hello, I have a GE PDW8280N00SS. It’s worked like a champ since installing it in 2007. A few weeks ago, it began to not clean upper rack items or the silverware on the bottom rack. No change in loading technique.

When opening the door during the fill cycle, there is very little water in the basin, and the fill port basically only has a small amount of water trickling out (not sure how quickly it might shut off when the door is sensed not closed). The fill cycle ends in less than a minute. A sticker on the fill valve mentions a three-minute timer. Not sure what would cause the timer to shut off in less than three minutes, unless the door is opened or the flood switch interrupts it. The filter screen built in to the fill valve is clean. The valve itself appears to be working, as it opens and closes on command. The flood switch and float are working fine.

There is zero clogging of any of the other filters or their assemblies, drain system works fine, water pressure at the shutoff valve under the sink is great, and the spray arm jets are clean. However, water pressure coming out of the inlet hose at the fill valve seems very low. I am using a “FloodSafe” water supply hose. A label on the hose says to disconnect and reconnect to reset the hose, but it is not shut off - simply very low flow when compared with a non-FloodSafe hose.

If I add water to the basin, everything seems to work fine, with water audibly hitting the door from the upper spray arms and with the spray arms re-positioned and with water dripping from them upon opening the door mid cycle.

So it seems the issue is that there isn’t enough water entering the machine. I’m guessing the likely causes for that might be:

  1. Fill valve (part 744) not opening fully or shutting off too early for some reason?
  2. Supply hose between household shutoff valve and fill valve clogged?
  3. Clog in the fill hose (part 576) between the fill valve and the inlet cover (573)/fill funnel (575)? I haven’t pulled the machine from under the cabinet to assess this possibility.

Appreciate any insight!
