I set my washer to run, it fills with water, starts to wash and the timer advances to completion in about 3 minutes ?

If it gets to the wash, but cannot tumble both directions (speed control), it will fault out and drain. There should be a technician sheet inside the lower panel to help you with diagnostics. This a Frigidaire product. Also check the inlet hoses and filter in valve. Another technician in had this issue a few months back. Where the timer was rapidly advancing through the cycles. The MCU controls the timer advancement.
