Spa Not Heating in Shelter Valley, CA
A Shelter Valley pool showing an attached spa that will not heat usually has a short list of likely causes. A spa that will not warm up usually traces to a stuck diverter valve, a heater fault, or an automation setting. Shelter Valley runs on Wells dominant at 16-22 gpg, which is very hard water. Around here that means extreme desert heat and very hard well water accelerating equipment failure, and it shows up in problems exactly like this one.
Likely causes in Shelter Valley
- A stuck or mis-set diverter valve keeping flow on the pool
- A heater fault the same as a pool heater no-heat call
- An automation spa mode that is not engaging
- Low flow tripping the heater high-limit
- A failed actuator on the spa return valve
What to check before you call
- Confirm the system is actually in spa mode
- Listen for the diverter valve turning when spa mode starts
- Check the heater for an error code
- Confirm the pump is running at a heat-capable speed
