Hi Nayana.

I'm having a hard time locating a manual, but dug a few things up for the seat. It appears to have temperature adjustments - it's unclear if there are manual ones, or if this is only from the remote control. It also appears to have a separate water tank, rather than a built-in heater. There is also a wall power cord for the heater and other valving / controls / actuators.

If the water is not heating, it could mean that:

1. The water heater is not ever heating up the water, so you have water the temperature it came in at. That could be a bad heater element, or a broken temperature sensor. Any commercial device heating things that come into contact with people will be built so that if the temperature sensor fails, or a wire breaks, it'll default to not heating. That prevents fires and scalding. This may mean replacing the tank, the heater element, or the temp sensor. You'd have to take that up with the manufacturer.
2. The temperature control hardware is malfunctioning. If it thinks the water is hot, even if it isn't then it won't heat it. Whatever sets the water temp, see if there's any change as you change the setting.
3. The water is hot, but is cooling off before it gets to you. Not likely unless you have a hundred-foot-long transfer pipe from the tank.
4. If it's the seat specifically and not the water, I don't know if the seat is heated by the water, or by an electric heater element. That could again be an issue of heater element, temperature sensor, or what temperature the control thinks it's set for.
5. The system is unpowered. I don't know if the spray will still work if the system is unplugged. if it is unplugged, then you won't get heat. The reviews specifically say it's tapped into the wall water supply for the toilet, so it'll be cold water coming in.

I hope that helps you narrow it down. Do also make sure the batteries in the remote aren't dead. One review I saw said the remote tends to eat them quickly.

Happy Holidays!

Did you have the head checked for warping and crack tested. because combusting gas is finding its way into the cooling system. have you replaced the thermostat .

They are not supposed to "stay" on. When the seat gets to temperature, it shuts off. This prevents overheating/overloading. If it is cutting out, then there is a bad thermostat governing temperature control.

if engine over heating coolant over flow jug will boil over you will see steam.sound like you have either faulty engine coolant temperature sensor or could have faulty fans relay or fuse or pcm problem if coolant fans dont turn on.have garage with code scanner that can do a snap shot on coolant temperature sensor check see how hot coolant temperature is see if coolant temperature over 220 degrees engine getting too hot.could have faulty water or blowed head gasket check engine oil on oil dip stick look milkly you have blowed head gasket. i use infra red laser thermometor check see how hot engine is over 107 celsius engine is overheating.

Turn off all power to the hot tub as soon as you realize it is overheating. The spa should have an automatic shut off when the water temperature reaches about 112 degrees fahrenheit. Call your hot tub dealer or manufacturer for service options. There are a variety of conditions that could lead to the overheating of your hot tub, but may differ in various hot tub models and brands. Check the water level of the hot tub. Low water levels could be the culprit for the over heating, so you may just need to add more water to the hot tub.
Check the shut-off valves in the hot tub. If they are closed while the hot tub heater is on, it could cause the water to reach unsafe temperatures.
Clean the hot tub filter. A dirty filter could be blocking the flow of water, causing the water to sit in the hot tub and overheat.
Turn the power back on after finding the problem and talking to the hot tub dealer. The hot tub will probably not start back up until the water reaches a safe temperature

Hello,
Does the the instrument panel indicate the car is getting to hot or overheating? Check the coolant level in your radiator to be sure but if the temperature gauge says the car is running at an appropriate temperature then I would not worry about the heat being to hot in your cabin. Just adjust the thermostat for the heat to a lower temperature that is more comfortable to you.

Regards, Tony

check to see if you are getting heat through the heater and then check and test your thermostat, if you require further assistance let me know. if this helps please take the time t rate this siote. and good luck.
