fatly over heat switch or tilt switch some r very picky

Did you see if there is anything on YouTube sounds like a bad element

The tip over switch was activated. Turn the Master ON/OFF Switch to OFF and unplug the heater for 12-15 minutes. Then plug the heater back in and turn the Master ON/OFF Switch to ON and set the controls as you normally do. Hopefully, that 10-15 minute timeout, allowed the heater controls to reset themselves.

Take good care of that heater, as the manufacturer has discontinued that model.

Hope I was able to help you.

It may be that the heater overload switch is shutting it off, because of overheating. Especially, if the heater is used a lot and is a year or more old. You can try to reset the overload switch by unplugging the unit for 10 - 15 minutes. Then plugging it back in again. If that doesn't solve the problem, you need to contact the manufacturer's Technical Service concerning this issue.

Also, cleaning the heating element with a vacuum that has a hose and brush attachment may help solve the problem. As the heating element may be clogged with dust and lint.

Hope this helps solve your problem.

Heaters have
)Tip over switch If the heater is thermostatically controlled then what you may have is the thermostat cycling just as a central heating system in your home. When heater reaches the temp you set it shuts off, then comes back on when temp drops several degrees below setting. Yes, It is normal. Ned
2)Thermostat

there might be timer setting or there coil is faulty.check it.

the control module is the problem it allows the heater to come on then turns off power to the gas valve.if you are not getting enough water flow the high limit is turning the heater off then your problem is flow.
