Pool heater will not flame

I have a Hayward h350ed1 and heater does not light. I get no flames. Water pressure is 18 to 20 psi, so seems good. Gas is on and after it tries to fire i can smell it.
i do not have a pilot light as it has a direct spark ignitor

Outlet water gets so hot it ballooned the PVC pipe like an anuresum. Lights and shuts down, assuming that is a limit switch working properly. Filters cleaned last month/water pressure seems adequate.


Your thermopile that tells the heater how hot the water is has failed. It should kill the heat at a temperature of 104f. This also indicates that the limits are not doing their job, as they should be killing the heat at 135f (low limit) or 150f (high limit). Schedule 40 pvc is rated at about 140f.
This many failures at once is rare, and typically indicates that the heater has been rigged. Get a tech out to fix it correctly. You are literally playing with fire.

Hayward H400FDN won't stay lit


It is probably not sensing flame. You either have a clogged orifice underneath the flame sensor and you probably need to have the gas pressure assessed, meter size and gas valve pressure adjustment. These heaters need 2" wc of gas pressure.

Does anyone know if the igniter also works as a flame sensor on a hayward h200 pool heater its an electronic ignition heater without a pilot light


Yes it does. Flame rectification is carried back through the ignitor assembly ground. Be sure all the points of contact are rust free between the ignitor assembly and the chassis.

Hayward H400 runs for 2 minutes and turn off, flames out chimney


Soot on your heat exchanger would explain this. Or leaves or rat nests would do the same thing. You can clean these yourself or get a repairman to do this for you. Just be sure if you have soot on the exchanger use a stiff bristel brush but not a wire brush. The soot as you free it up will be pouder and can explode in a fashion. Be careful and good luck.

Sounds like this is a flame sensor issue. It is not detecting the flame.
