Hello- My pool guy was out this week repairing a valve that cracked due to water making it's way into the pool return- our pool is currently closed for the winter and the hot tub remains open; somehow the toggle on the actuator got flipped (???) and water made it's way into the pool returns. While he was here he recommended taking out the section of pipe you see in the first picture to rule out any possibility of water making it's way into the pool plumbing during the winter. He then plugged up the pipe with an expansion pipe plug and left the actuator open in both directions. I went to use the hot tub for the first time last night and found that after about 5 minutes, the heater is shutting down and the Service Heater light is coming on. I'm wondering if this new plumbing and valve configuration is causing a water flow issue that is triggering the error. I'd like to try putting the valve back to 100% into the hot tub but not sure how to do that? Any thoughts, advice or direction on how to trouble shoot this? PS- fortunately the heater is able to come on long enough to maintain the water temp above 70 and avoid bigger issues in our cold, Colorado winter. Thx!

The handle of the valve right after the SWG cell should point toward the heater, that should be "spa" position. Put your system in "spa" mode. Use the small toggle switch on the bottom of the actuator (its probably in its middle position) to make sure the handle moves and stops while pointing there. Put the switch back into the center position and the valve will no longer turn.Hello- My pool guy was out this week repairing a valve that cracked due to water making it's way into the pool return- our pool is currently closed for the winter and the hot tub remains open; somehow the toggle on the actuator got flipped (???) and water made it's way into the pool returns.

You may be bypassing too much water around the heater and it could be throwing error codes. Try closing the bypass valve a bit more and see if that works. Or, increase the pump rpm and give it a try.

Hello, thx for the advice but unfortunately neither of these worked. I have a tech coming out to see if my issue is covered under warranty.

Turns out it was the float switch (error code FS). I guess it's common for the condensate hose to get gunked up on these units causing the float switch to trip and shut off the unit. I didn't see exactly how he cleaned it but the tech said that if it happens again you just need to hose it out really well (it took him less than 10 minutes from start to finish). My unit had been in service for less than 2 years so this seems soon but what do I know. I'm going to have my guy be sure to check it each open and close.
