I have an in ground pool and spa with a Waterway Plastics Oasis controller, pentair intelliflo variable speed pump and mastertemp 400 natural gas heater. Two days ago, my pool water temperature was 57 degrees F. I heated the pool for 6 hours up to 81 degrees F. I then pressed the pool heat button to turn off the pool heat and the screen showed a countdown of 55 seconds for a cool down cycle. I waited until that was completed then I pressed the P/S mode button on the Oasis controller to switch from pool mode to spa mode and then I pressed the spa heat button. The screen on the oasis controller showed that the pump should be running and the heater will start soon but the pump never started nor the heater. I waited 10 minutes then switched it back to pool mode without pool heat and the pool pump won't start. I checked all the power cords, communication cord from the oasis controller to the pump and the electrical panel breakers and all was fine and on. I can run my pump manually by pressing one of the 4 preset speeds in egg timer mode. So I know the pump is working. Does anybody have any ideas of what I can try? I troubleshot many scenarios and even talked to technical support at Waterway Plastics for the Oasis Controller. They were stumped.
