Did you ever find out how to do the bypass? I'd like to get to 106....

If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes. There are a few reasons that this might be happening. They range from air in the gas line to inadequate gas flow. Start by checking the installation

Unless you have rigged your unit for remote control, this control panel is the only one listed. You can check this link for contact information http://www.hayward-pool.com/prd/In-Ground-Pool-Heaters-Universal-H-Series-Low-NOx_10201_10551_14002_-1_14003__I.htm

Headers on hayward heaters are usually warranted for 10 years, except for freeze or chemical damage. You may want to contact a local warranty station to see if you can get it replaced under warranty.

Adjust the switch fully in the opposite direction. If you are at 1.5 you are at the light end of the adjustment range of that switch, which can be adjusted up to 5psi. Then let it back off until it works reliably. Rarely do you need to adjust a pressure switch on an above ground pool so it should end up about in the middle of the adjustment scale.

HF Flame present with gas valve "OFF" error If flame is sensed with the gas valve off the control will go into lockout. The blower will run until error condition is corrected. When corrected, control will run blower for 5 s then automatically restart after 2 minutes. the error might be caused by a faulty flame sensor. i have heard of this happening the other way (carbon blocks sensor causing no ignite)

All electric motors run hot and pool pumps are no different. But how hot is too hot for a pool pump? The first test is simply whether you can touch the motor or not. Under normal operating conditions, the motor end of the pump is hot enough that you can barely touch it - but not searing hot.Best to you.https://www.google.com/search?q=XtremepowerUS+2HP+In-Ground+Swimming+Pool+Pump+Variable+Speed+running+temp&newwindow=1&sxsrf=AB5stBhpriuNhnfXLYYTg7tuS-LWwW262g%3A1690815381903&source=hp&ei=lcvHZKH_NOHi9AOquJjADw&iflsig=AD69kcEAAAAAZMfZpVdAAi94QXZiwKfN3nArsWv-Gm1z&ved=0ahUKEwjhnd6RmrmAAxVhMX0KHSocBvgQ4dUDCAo&uact=5&oq=XtremepowerUS+2HP+In-Ground+Swimming+Pool+Pump+Variable+Speed+running+temp&gs_lp=Egdnd3Mtd2l6IkpYdHJlbWVwb3dlclVTIDJIUCBJbi1Hcm91bmQgU3dpbW1pbmcgUG9vbCBQdW1wIFZhcmlhYmxlIFNwZWVkIHJ1bm5pbmcgdGVtcEgAUABYAHAAeACQAQCYAQCgAQCqAQC4AQPIAQD4AQL4AQE&sclient=gws-wiz#kpvalbx=_sMvHZMuPJPez0PEP3M2LgAY_44

Testing the water pressure of your Hayward gas heater is a relatively simple process. Follow these steps to check if your water pressure is working properly:

1. Turn off the Gas Heater: Before performing any tests, make sure the gas heater is turned off to avoid any potential accidents or injuries.
2. Check the Pressure Gauge: Locate the pressure gauge on your Hayward gas heater. It is usually located on the front panel of the unit or near the plumbing connections.
3. Observe the Pressure Reading: The pressure gauge will display the current water pressure. It is typically measured in pounds per square inch (psi). The optimal water pressure for most pool heaters is usually between 15 psi to 25 psi, but it's essential to check your heater's manual for the specific recommended pressure range.
4. Turn on the Pool Pump: Ensure that the pool pump is running, as it is responsible for circulating the water through the heater. The water pressure will be at its most accurate when the pool pump is operating normally.
5. Monitor the Pressure: While the pool pump is running, observe the pressure gauge to see if the water pressure falls within the recommended range. If the pressure is below the minimum recommended level, it may indicate a circulation issue or a problem with the pool pump.
6. Check for Leaks: While testing the water pressure, inspect the heater and the surrounding plumbing connections for any signs of leaks. Leaks can lead to reduced water pressure and affect the heater's performance.

The code you are referring to is actually IF, not 1F. It stands for ignition failure. If the control exceeds the maximum number of ignition retries or recycles the heater will shut down and go into lockout. Automatic reset is 60 minutes.

Question edited for a lot more clarity Question moved from Cars and Trucks. The pump appears to be made by Hayward, yours just has a Century badge on it. The fan doesn't appear to be a replaceable part, so try Hayward direct. https://www.google.com/search?q=maxflo+vs+500+parts ..
