Purchased a new home last winter with this hot tub. Nothing but problems from the start. Previous owner said everything worked. First the keypad went out and the system defaulted to 80 degrees. Spa ran like this through the winter (heated at 80 degrees). Early spring the recirc pump failed so I drained the tub. A few weeks ago I replaced the keypad and recirc pump. I then filled, did ahh-some treatments and drained (3 times). Both power light and ready light flashed from the first fill to the last. Heater never came on. On the 3rd and last fill the breaker started tripping as soon as the pumps were turned on. Checked pumps and found pump 1 is tripping breaker. Disconnected pump 1 and everything works (except heater). Still have both lights flashing. Today I replaced the Control Thermistor and the High-Limit Sensor. Still have problem. When I jumper (bypass) the pressure switch I get a fast blinking Power light only and the keypad becomes unusable but recirc pump is running. If I unplug pressure switch I get the same two lights flashing as I do when it is plugged in. Everything else works great... recirc pump, pump 2 and ozonator. Recirc pump has great pressure. I've tested it with and without the filters. Voltages are all good. Running out of ideas.
PUMP 1 failure theory: The seal around the light was leaking and dripping directly onto the electrical end of the pump. Not sure how long this went on. Thinking it may have some corrosion on the inside and either arched across the leads or just died. Pump turns easily by hand. I'll fix or replace it when I drain the tub. Need to fix the heater issue first, don't think they are related.
What am I missing? Any ideas?
