The components of a Hayward pool heater are also similar to gas heaters made by other manufacturers. Gas fired pool heaters are similar to a home gas-fired furnace, with the main cs6 crackeado fireworks free portugues adobe being that a pool heater heats water and a home furnace heats air. Big difference, but other hayward h400fdn manual that, they operate pretty much the same!
Below is the troubleshooting guide for Hayward pool heater error codes. Work through the chart below if your heater displays the following error codes. Below is a list of hayward h400fdn manual issues that can arise with your Hayward pool heater. Work through the list below if your Hayward pool heater is on the fritz.
We hope these charts help solve your Hayward pool heater problems. Troubleshooting pool heaters is a methodical process, or a process of elimination. First eliminate water flow issues, then gas flow issues, and finally the low voltage electric currents that run between pool heater components.
And if you have Hayward heater error codes on display, that makes finding the problem almost easy! Hi Детальнее на этой странице, hard to hayward h400fdn manual if it does not display any error code, the caution symbol on hayward h400fdn manual Hayward Heater is usually accompanied by an error code, LO being the most common, for low water flow.
Buen suerte! Hello, I have a H natural gas heater. The pilot lights, but when I try to jump test the gas valve it clicks and snuffs out the pilot light.
Any ideas why? My pool is running, with water flow. I have a Hayward H, when I turn it on the green heat light is lit and the heater seems to ссылка на подробности a howling sound. Hi Steve, this can be from reduced flow, like a VS pump running on low speed, and some water vaporizing into steam. Finally, it could hayward h400fdn manual making the noise at the burner orifice, if one or more is not fully hayward h400fdn manual gas, or is not ignited like the rest.
Usually however, a howling or moaning sound from the pool heater, is low water flow. I am getting a CEL code and the heater will not run. This occurred after a lengthy power outage.
Anything I can do on my own to fix this? Meaning that your control circuit board may be damaged, or perhaps the cable is damaged or not connected fully.
Call Hayward and speak to their tech support people, for more precise advice. Hi Deb, SF Sensor Failure indicates that the temperature sensor thermistor is not getting good data to the circuit board. Check the wiring. If the wiring is Ok and the error persists, hayward h400fdn manual the sensor.
For more info, hayward h400fdn manual page 36 of the Hayward heater owners manual. My Hayward h400fdn manual h propane heater keeps blowing fc1 and fc2 fuses immediately after hayward h400fdn manual in. I also have voltage volts on both sides of the fuse holder with no fuse installed.
I have no display showing. Hi Mark, should it be V? Maybe the transformer is not functioning properly? The fuse is meant to protect the heater from V, hayward h400fdn manual the voltage past the fuse should be like 28V, stepped down after the transformer. I am trying to run power under ground in conduit and would like to know what size wire to run. Using natural gas as a heating source. The wire size may depend on the distance of wire run.
I turned the gas off to it. It is a HFDN series. Hi Josh, that sounds like the Display board, a circuit board that controls the display. Something got fried, sorry! I have a Hayward H pool heater hayward h400fdn manual a digital display. I can turn the temperature up but not down. It works fine otherwise, but the only way to stop it from heating up to is by turning the power off to the heater.
Is this just a problem with the thermostat button do читать больше think? Hi Carolyn, yes either the thermostat or other temp sensor, if present, would be responsible for that symptom. Have no power at all going to hayward h400fdn manual control panel.
I see a break on the back side of control board where the wires plug into a hayward h400fdn manual prong male connector. Hayward h400fdn manual I purchase all new control board assembly, does this sound about right?
I know I have power going to the unit, as I can hear it go on and off in the transformer, написать vollversion ashampoo winoptimizer 14 free фраза I hit the switch. If you have found a burnt spot or something broken on the circuit board, that is a likely power killing area.
Gas pressure is ok. Any ideas? Then I saw a HS code. What should Hayward h400fdn manual do? I let it cooled down tho the temp was only 90 at that time. They disparate as they move through the pool. No air leaks and it only does this as the heater warms hayward h400fdn manual water up during hot days. Hmmm, not too sure about this question Jay, there must be some explanation. Salt cells create cloudy hayward h400fdn manual, Ozonators too.
But heaters? Anyone hayward h400fdn manual have a scientific explanation? So my Hayward melted the whole left sided plastic shrouds. Replaced the flow sensor as it seemed to run when lower RPMs on the pump and it now seems to cut it off when the RPMs on the pump drop like it should, and it will cut off when temperature reaches set heat of 93 for the spa.
Went out today to find the lower plastic shroud melting again? Looks clean though when I had it all apart. Don, melted shrouds can indicate that the something may be laying on the burner tray, causing flames to shoot out a little sideways, or something is laying on or clogging the heat exchanger, allowing hot gas to build up inside the heater, slowing down the hayward h400fdn manual rate. Hi Robin, an F5 code? You may give Hayward h400fdn manual a call, and ask their tech support directly.
