Question about Hayward H Series Millivolt 250,000 Btu Pool Heater H2501

1 Answer

My Hayward pool 350000 heater will light and stay lit and heat the pool for a while, but will just shut off including the pilot light. When I re-light it it works for a while again and then shuts off again. Can you help me? Is there something that I can do before I have to call someone to come and look at it? Thank you, Ron

Sounds like the pilot assy needs to be replaced. It has 2 functions one is to light the main burner but also to let the system know that the burner is lit. If it thinks the burners are not lit it turns the gas off

Why will my hayward h 250 millivolt pool heater pilot light not stay lit


Looks like your pilot generator may have some corrosion on it. Follow the stainless steel tubing on the gas valve as it goes down to the burner area. At the end of this is the pilot assembly. If you can remove this so your able to work on it you will se a short metal rod that the pilot flame touches when lit. This generates current that keeps the gas flowing to the pilot to keep it lit. Take some sand paper and give it a light sand to remove any corrosion on it. Reassemble at put it together. You may also need to clean the pilot tube(stainless tube from valve). Small spiderwebs can reduce the flow to the pilot and cause this problem also

Hi I have an Hayward H Series pool heater and the pilot doesn't stay lit when I depress the control to turn it on. Any quick solution for that ?


Check the thermocouple that the pilot light heats up. If it is not working then the gas to the pilot will not stay on.

Your problem is the pilot generator where the flame is by the burners. This needs to be repalced. That is what is causing the pilot to go out and not start. It is a flame sensor and also tells the gas valve when to release more or less gas.
