Hot tub motors work simultaneously with your hot tub pumps to move water around your home spas and portable hot tubs. This page of Hot Tubs and Portable Spas goes over hot tub motor information.
The size of your hot tub motors depends on how much water your hot tub will carry, and how much water it will need to push around. As a general rule of thumb, 1HP hot tub motors will be sufficient for a hot tub spa that carries 700 gallons of water or less. Because of this you find these 1HP hot tub motors in most 2 person hot tubs. Anything with more HP than than will be required for hot tubs that are larger in size.
Hearing a buzzing noise is a common problem of hot tub motors. This means that something is keeping the hot tub motors from turning, which might be a stuck shaft or bearings. When bearings get old and worn out, they can cause a jam in the hot tub motor as well.
Replacing a hot tub motor is usually not recommended, since it usually costs more and isn’t worth it than to replace the whole pump. If you are considering replacing a hot tub motor, you should probably just replace the whole hot tub pump and hot tub motor unit. If you really insist on trying to replace a hot tub motor, then you can buy them from your local hot tub stores, or online at the Spa Depot.
