Easy DIY: basic tools, under an hour. Moderate: some disassembly. Advanced: experience with the machine's internals. Technician: sealed-system, electrical or tub-split work.
Parts prices don’t move much across the country; labor does. If a technician supplies the part, expect 40–50% on top of the part price.
