With no clothes in the machine, set it on the Regular or Heavy cycle, advance to the final spin, press Start. What happens?

Check the Fault Code and test the lid switch and out-of-balance switch via this procedure:
- With the power off, press and hold Wash Temp Down, then press Power at the same time. There should be two short beeps and the machine powers on in Diagnostic Mode. Release the buttons.
- Press Spin Speed Up and/or Down until BOTH the Slow and Hold lights are on. The eight cycle progress lights indicate the last Fault Code that occurred. Make note of which lights are on from left to right (1st, 2nd, 3rd, etc.).
- Press Spin Speed Up and/or Down until the Medium spin light is on.
- The 12 Min wash light then indicates status of the lid switch. With the lid CLOSED the light should be OFF. With the lid OPEN the light should be ON.
- The 6 Min wash light indicates status of the OOB switch. Push and hold the tub toward the right-rear to activate the switch, the light should turn ON. With the tub centered normally, the light should be OFF.
- Press Power to exit Diagnostic and turn the machine off.

spin cycle it pumps (recirclates ?) water in tub then goes to pump out / spin it doesn't, it beeps, and wash rinse and spin lights come on and remain on

There shouldn't be any recirculation via the pump during spin. Recirculation occurs only at the start of a cycle, during the Eco Active wash phase (basket rotates at 25 RPM), and possibly one time for a few moments during rinse. If you are getting recirculation when the machine should be draining, then your diverter valve is probably bad.

Test it via this procedure. Is there water in the machine now? It needs a few gallons to do this test.
- Get into Diagnostics per the previous instructions.
- Press Wash Temp down to run some cold water in if needed.
- Press the Delicate cycle button and wait a couple mins. This activates the diverter valve.
- Press the Regular button (do not turn off Delicate yet). Water should recirculate into the tub via the port at right rear of the tub. It should NOT drain.
- Turn off Regular & Delicate. Wait 3 or so mins for the diverter to deactivate fully.
- Press Regular to turn the pump on, it should drain and NO WATER should come from the recirculation port.

If the pump recirculates when it shouldn't or drains when it shouldn't, then the diverter valve is either broken or clogged with lint. The valve mounts under the tub near the pump. Has three hoses attached ... one coming from the pump, the drain hose, and the recirculation hose. It's not an expensive part to replace.

Also, VERY IMPORTANT ... examine the pump for signs of leaking. The pump on GWL10 is part of the machine's power supply circuit to the controller board. If the pump motor windings get wet/corroded from a leak, even a small leak over time, the pump can short-out or go to high resistance and zap the controller board.
