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

SOURCE: pilot will not stay lit after button release

most likely you have a thermopile that has low output. it takes about 100mv to maintain pilot light

SOURCE: Hayward 250 heater won't fire up

Check the control circuit, specifically the pressure switch, for continuity with an ohm meter....any reading over 2 ohms needs to be investigated

My Hayward h250 Millivolt heater won't stay on. If I jump the "TH" connections I can get the main burners to come on, once I remove the jumper, the main flame goes out. I replaced the pilot assembly and...

you prolly have an electrical short somewhere. follow the circuit and if any safety is getting around 200-250 dc millivolts then theres the problem. otherwise you have an open safety switch, or tsta controls

How do i light the pilot light for the hayward

The lighting instructions are usually located inside the heater on the inside of the access panel or on the firewall near the gas valve.

Most millivolt heaters require you to turn the gas valve knob to the pilot light position and then depress the knob while lighting the pilot through the pilot hole. This varies depending on the exact model.
