Q: I have a Hayward Electric Spa Heater CSPA XI. My unground pool with attached spa was installed in 2017. This will be my third heater installed in the system, they keep shorting out. My first installer retired and I can't get the local pool companies to come out. My pool is 24x12 w/attached 6 person spa. Is this heater too small? Why do you think this keeps happening?

Q: My heater is under three years old and it will no longer turn on aside from when the pump is initially turned on for a few seconds, then clicks off. I contacted the authorized service company near me and they have been nonresponsive. What do you recommend? I do to resolve the issue?

Q: No matter what heat temp I set my CSPA xl spa heater, it heats the water to 109. Tried turning down, but then the element wouldn’t turn on. Turn knob back up and heated to 109 again. Is there any adjustment so that I can get it to stay at 104.

Q: I purchased a house w an existing hayward cspa xl electric heater. I want to utilize the spa but not damage since I have not used it before. It has a dedicated pump seperate from the pool. It has a programmable timer to turn the spa pump on as needed. Obviously the pump has to circulate to move water thru the heater, but leaving the pump running 24/7 is not very efficient. My question is: when I turn on the thermostat to heat w the cspa xl does the heater also have an internal sensor to shut off when water is not flowing to avoid burning up the elements? For example: if I set my heat to full heat and set my timer to run pump from 5 til 9pm will the heater sense the stoppage of water flow outside of pump run time?

Q: Hooked up 220 wire to cspaxi -11 heater but it wont come on. When we took cover off there were two control wires a yellow and a blue that wasn’t hooked to anything so we didn’t know if that was possibly the reason why it won’t come on?
