<<<However, this time wires were fine>>>
**********
Verify that all previously repaired/taped wires are fine (especially the thin low voltage wires).
Inspect the wires at the bottom of the door too---inside the plastic sheathing.
Re-tape the entire harness from the bottom of the door up to the detergent dispenser housing.
Add a small section of cardboard between the wire loom and the tar-like insulation on the door.

<<<so I assumed it was the motor (the one that has the blade & plastic impeller on it). I've swapped that out, but I'm still getting the LE error.>>>

It's common for DIYers to *forget* to plug the new WASH MOTOR.
Verify that it's plugged in---from the bottom of the dishwasher---with the lower kickplate removed.
Purchasing a WASH MOTOR only---is a huge risk.
Check the Build Date on the bottom of the WASH MOTOR---if the date is June 2008 or newer---should be good.
If an older build date---a flawed motor.
I recommend replacing the entire SUMP ASSY (
AJH31248604) to avoid accidently receiving older/obsolete/factory-defective-as-new/no longer used inventory.

<<<However, the largest gasket (with all the bends) was torn up/broken in a few spots.
I'm going to order one this week, but I was wondering if anyone knows if a bad gasket could be the sole cause for the error?>>>
************
No.
An improperly installed or damaged Sump Assy gasket will cause poor wash performance.
