Question about Hayward H Series Pool & Spa Heater 400k Btu Propane Gas Milivolt Ignition H400p1

1 Answer

I have a Hayward H series spa/pool heater. It will not light.

I have not used the heater for over 6 months. The mode lights work correctly. It is on Standby as it should be. I selected SPA and set the temp for higher. The mode light flashed green but the heater did not light. Then a fault code of 1 F appeared. The same sequence of events occurred in the Pool mode. Should I have the tank filled and the system bled before I call for maintenance? Or do you have any other suggestions? Thanks, Phil Ragan

IF stands for ignition failure, one possible cause is that the two sparker prongs are not spaced properly, i have seen this before several times. The correct distance for them to be spaced apart is the width of two quarters side by side... not like this....OO, the other way so the are flat. To access that you have to take out the heat exchanger, which requires unhooking high limit switches in the back, unhooking the pressure switch, thermostat wire, and plumbing...just remember where everything goes. Before you do that though check this simple thing...there are a number of brass orifices that shout gas to the burners, use a 7/16 wrench to take off the one that is to the extreme left, which is on the igniter side of the heater, inspect the orifice to see if there is blockage, like a spider web or something. If it is blocked, clean it out and also look down the burner itself to see if it is free of blockage. And because we all make simple mistakes.......make sure the gas is on.
