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.

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

Pool heater throws code h5? smoked


HS
Water Temperature Sensing Error

A) Inlet water temperature sensor is reporting a temperature in excess of 104 degrees.
Normal operation resumes 2 minutes after inlet water temperature sensor reports temperatures of 104 degrees or less. This error functions in both normal and remote thermostat modes.
or
B) Inlet water temperature sensor is reporting a temperature change at a rate faster than 6 degrees in 60 seconds, indicating a potentially damaging low water flow conditon. Normal operation resumes when temperatures stabilize. If this condition is detected 3 times, the heater will lock-out until the electrical power is cycled off and back on.

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

H250fd. I have the service light lit when I turn the system into standby and shut off my pool pump. Is this normal?


This is not normal. You have some sort of electrical short. Possible bad fuses, wiring, or board if its not showing a code on the display

My hayward pool heater gives me a code sb what part is this


Possibly failed keypad, or stuck key on keypad.
This product should be under full warranty, and installer should be called.
Hayward 350 product manual: Error codes start page 38 do not show Sb
http://www.hayward-pool.com/pdf/manuals/Manual285.pdf
However Sb error code shows on following manual as 'Keypad failure' or 'stuck key'... one of the keys is stuck longer than 30 seconds, but control will still function, replace keypad.

Hayward H400 Pool heater will not stay lit


"IF" - Hayward Pool Heater Fails to Ignite: the most common reason for this problem is insufficient gas supply. The Hayward heater LED display will show a diagnostic fault code of "IF" which stands for Ignition Failure. Undetected gas pressure problems if not investigated properly may result in unnecessary replacement and servicing of your Hayward Pool Heater.
