Replaced lid switch on my ge brand washer I thought was bad. Turns out it wasn't. Wondering what to check next?

What is your machine NOT doing? Is it not agitating or spinning or both?

If not agitating the problem could be
Water level switch faulty.
Lid switch or timer faulty.
Drive belt or pulley loose
Motor or transmission faulty.

If it does not spin:
Lid switch or timer faulty.
Motor or transmission faulty.
Pump blocked or impeller jammed.
