my hot tub will turn on and pump water for about an hour before the pump shuts off. after this happens there is a fl1 (flow problem) code on the display. the motor is too hot to touch for more than a second. after a few hours the motor will work again for about an hour till it shuts down again. Ive already replaced the pressure switch and temp sensor. is the motor shot? via /r/DIY https://ift.tt/3jMV3HQ
