    I am having the same problem. The heater was working fine and then one day when I turned off my pump to clean the screen, the heater did not fire up when ai turned the pump back on. I checked the pilot light and found it not lit. I have tried lighting it several times but everytime I release the control valve knob the pilot light goes out. I am wondering how you check the thermocouple to know if it is working properly.

    I have a similar problem. I have a spark, but my pilot light will not ignite at all. And I don't smell any gas. Anybody have a guess as to whether this is the gas valve or the thermocouple? Thanks!

    the pilot would lite first time but burner would not kick in on recomendation from jandy engineer i changed the water pump now using a marlow itt 1hp, after fitting the burner kicked in for approx 3 mins now i have no pilot and no main burner, i have had this unit for 1 month from new and it has worked for approx 3 minutes i could heat more water with a candle, stay away from Jandy.

If you have not found the problem yeat, it IS the thermocoupling( or pilot generator(same thing))
You may test by placing a multimeter on the red and white leads coming to the gas valve. you do not need to disconnect the leads first but you can

We have a teledyne gas furnace whose pilot won't stay lit. Any ideas?


Is this a standing pilot,or pilot always on.

If so a bad thermocouple will cause pilot to go out.

Thermocouple is a small copper tube running from the pilot light area to the gas valve. easy to replace.

It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.
