My Maytag Neptune stopped mid-rinse last week. I found it had tripped the circuit breaker which was surprising.

After some troubleshooting, I found the normal wash cycle, rinse cycles #1 and #2, and spin cycle run fine. It's only when the timer goes to rinse cycle #3 does it trip the circuit breaker. I was able to repeat this consistently. The circuit board seems fine.

I thought it might be the timer so I replaced that but I still have the same problem. It shorts out ONLY on Rinse Cycle #3. It's the strangest thing. Any ideas?
