I think you may be right. The weird thing is last night I got it to work for the first time in about 3 weeks. It ran perfectly for two cycles. Then, I went home for lunch today and tried running it again and it was back to not working.Sounds like the motor is going bad. If you have an authorized service center nearby, they can repair it. A new motor runs about $300-$400 plus labor to install. If you call Dolphin they can tell where the nearest service center is but shipping costs can add another $50 or so to the costs.
