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.

My Hayward H400FD is showing a H5 or HS error code, what does this mean, and what do i need to replace?


HS represents a problem with the temperature being too high. (maximum return water temp exceeded). this can be caused by a restriction in the plumbing system. i have that problem when i start my pool after a cold night. the water temperature rises too fast and the heater protects itself by flashing that code and turning off. reset the power to unit and it should work ok. if not, you may have to dig deeper as to why this code is being generated

Why does my hayward h250fd have and if error code? it is a brand new heater


If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes.
There are a few reasons that this might be happening. They range from air in the gas line to inadequate gas flow. Start by checking the installation

What does this mean Hayward pool heater h150FDN gives us an hs or h5 error?


HS = High Limit Sensor
Heaters Maximum Water Temperature has been Exceeded.
A few reasons this occurs...
  • Low water flow thru heater, check :
    • Dirty Filter
    • Opened By Pass Valves
    • Plugged pump impeller
    • Dirty/Full baskets at skimmer or pump
    • Anything that may reduce water flow
  • Sensor could actually be doing its job, in a different aspect, Thermostat failure, and water is overheating in spa or pool?
But anyway, your heaters fault code you asked about is: hs, not h5

Hayward GAS HEATER KEEPS GIVING ERROR AO blower vacuum switch error? is this an electrical problem or does it mean the switch went bad, what do i look for?


This means that either the switch is bad, the wiring is corroded, the fan is not working, or the air switch tubing is broken or cracked. Follow the air switch tubing all the way to the end, remove it and check for cracks. This is the most common. Also check wiring connections for breaks, or corrosion.
If all looks well, replace the air switch.
Also, before any of this, make sure the fan is coming on at start-up.

Hayward H250K gas pool heater error code


Low Flow errors are not necessarily real. They can be caused by improper adjustment or a defect of the pressure switch. Locate the pressure switch. Verify that the "switch" makes contact. Adjust the dial, reducing the distance the switch has to travel to engage. This will effectively lower the operating pressure required to operate. Keep adjusting until the unit stays on.
