I have an 8 year old Hayward heat pump that started acting up yesterday. The pool temperature read 95F when I first turned on the heater and then continued to go up until it reached 114F. The actual temp of the pool is about 82F. I tried it again today but put it in spa mode for but same results, only this time it fluctuated between 103-104F. It ran for 5 minutes and then stopped. It continued to start and stop every 20 minutes or so; start and stop was it though, literally coming on for 2 seconds each time. Hopefully it's an easy diagnosis as we are having guests next week and would like to have use of the spa.
THank you.
