owyheedog Posted June 14, 2013 Report Posted June 14, 2013 My CalSpa hot tub has recently begun acting up when it starts to cycle. It will kick on but just hum loudly like the motor is stalling. This usually continues for 30-60 seconds and then it works normally. If I hit the high speed jet buttong while it is doing this it takes off just fine. Any ideas? Quote
