This is not normal. You have some sort of electrical short. Possible bad fuses, wiring, or board if its not showing a code on the display

Why does my hayward h250fd have and if error code? it is a brand new heater

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

Intex pool pump runs for five minutes and then shuts down and service light comes on. What could be the problem as it was running fine the day before?

We don't have a service light on our pump, but usually when our is playing up it's because the pump is struggling to push enough water through - for example if the filter needs changing or if the skimmer isn't receiving enough water/water level is too low.

Pool filter pump won't shut off.

I'm assuming it continues to run when you switch the system to "service" mode. You probably have a relay stuck shut. Unless you are very comfortable with working with high voltage it's best to get a tech out to verify the problem and switch out the relay. If you are okay with it the replacement isn't very difficult. You'll have 4 or 6 wires to move from the old relay to the new one, and switch out the small black and red paired wires that go from the relay to the control board. Make certain that your breaker is off while changing it out.

Have you called your local Watkins dealer for a service call?
I can have you look at a couple of things before you call it in.
Once you turn the system on it will operate without the heater on to purge the system of air. Once that few minutes has gone by the heater will turn on and they system will operate normally.
At what point during this cycle does the system shut down? Does it blow the circuit breaker? Exactly HOW does it shut the pump down?

When the system shuts down the water inside the heater collects residual heat in the heater. For most systems that have intermatic timers (yellow dial) you can get a fireman's switch kit that will shut the heater off about fifteen minutes before the pump goes off to let it cool down. If you have electronic controls you should have one built into the system and will just have to activate it.
No promises but this could cause problems with time.

Pull the cover off the control panel. You will probably find a button which would be accessible from outside the panel with a paper clip or pencil but is unlabeled. On the board itself by the button, in small letters it should say "reset". Push the button and see what happens.

Sounds like the pilot assy needs to be replaced. It has 2 functions one is to light the main burner but also to let the system know that the burner is lit. If it thinks the burners are not lit it turns the gas off
