The other day I put some chemicals in the hot tub and turned it on and ran the jets to mix everything up good. I remembered I left the light on later in the day so when I shut it off I have to cycle thru the jets coming on and the low speed worked fine but when the high speed came on I can hear the motor spinning and see the water is still ciculating like it does on the low speed but the motor is clicking and wont go into high speed. Is this the sign of a bad motor?

I dont have a clue on a make of the tub but the motor is a magnatec and the control box is a balboa wired 240v

Thanks for any help
