WHIRLPOOL DU1145,,,cleaned debris from chopper etc but cannot seem to get lower spray arm back on correctly....very wobbly...any suggestions? thanks

I did the same exact thing, and ended up with the same result, A very wobbly lower spray arm. Despite it wobbling and hitting the feeder tube to the upper spray arm, it works.... somehow....

I do not have a huge amount of information about the GE Profile PWD7880 handy, so I don't know if it has a chopper blade/food disposer at the bottom of your Dishwasher, but when a dishwasher gets the holes of the spray arm, the most common cause is the chopper blade is jammed/blocked. Then the food debris never gets sliced and diced at the end of the of each wash cycle.
Opening up the filter under the spray arm, removing as much of the lower assembly and inspecting every where in the sump area, especially the drain pump area would be a great beginning.
Good Luck! Just ask if you have more questions.

The top rack is not cleaning because of low water pressure from the wash motor to the upper spray arm.
Assuming the top spray arms are clear of debris, remove the lower spray arm and lower feed tube to access the wash motor. Remove the 4 torx screws and the filter (accumulator assembly). Remove the torx screw and the inlet protector that covers the chopper assembly. Make sure the chopper is not broken (broken chopper will fill with debris and block water flow). While holding the chopper blade, reach inside the "D" shaped opening on top of the motor and spin the wheel/motor by hand in each direction to make sure either the chopper gear or the motor gear that drives the chopper is not broken. Replace the chopper if necessary (part # 8268383). If the motor gear is broken, replace the sump and motor assembly (part # 8535150). Remove any debris from the sump area in the process.
You don't have to shut the power off to the dishwasher because the door will be open, but if you feel more comfortable, do so.
Good luck!

It looks like there is not enough water pressure to spin the spray arms. Loss of pressure may be due to various things, like damaged seal, cracked tubes, clogged filters, screens etc.
I suggest you take a look at the technician repair sheet that should be stored inside the front panel at the bottom of the door. Remove that panel under the door with screw driver. Inside, attached to the panel, you should find a troubleshooting guide and solution for technician. But it is easy to follow. Look at the section under "poor wash" and follow its recommendation. I had exact same problem - not enough water pressure. In my case, the chopper screen was clogged and the chopper assemply was broken. I followed the repair instruction above to remove the chopper assembly, cleaned the chopper screen and the washer now is as good as new. I will need to replace the chopper when the part arrives.
Good Luck

Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.

Check water level:
Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.

Inspect food chopper:
Remove lower spray arm and rear water supply tube to upper spray arm. Remove torx screws that secure the sump cover. Remove the rounded cover on the left side to expose the chopper assembly. Inspect for breakage of blockage. There may be an additional plastic screen to remove first.
