HS = High Limit Sensor
Heaters Maximum Water Temperature has been Exceeded.
A few reasons this occurs...
But anyway, your heaters fault code you asked about is: hs, not h5
SOURCE: Our Hayward gas heater keeps giving us a H5 error
Could the Error code be HS? That is high temperature limit. Perhaps you' don't have enough flow, allowing the heater to heat the water to a temperature higher, than the thermostat setting. Make sure your bypass valve is closed, allowing full flow through the heater. Check your filter pressure differential , and skimmer baskets.
You didn't give your model number, and there are many models. You can go the Hayward website below and select your exact model number and download the manual. The manual will explain each error code.

Yes thank you very much TOM W. That was the problem. The bypass valve was open on mine and gave me the HS error. Turned the bypass valve off and worked beautifully.
Thanks again.
