Did you check all the outlets/receptacles in the house with one of those LED plug in testers to see if any show the hot and neutral are reversed, and if grounded?
I used to be a technician for a packaging machinery company and one customer kept calling us that his machine was acting erratic.
Another tech had replaced the control box twice under warranty and it was still erratic. The customer was pissed and wanted his $14k refunded for the machine.
I went out there and noticed they had it plugged into a heavy gauge extension cord that had a replacement female end which tested bad with my plug in tester, they reversed the hot and neutral on the cord. The wall outlet tested good.
So it could be something simple that will not require vector math and o-scopes.
