Not sure, my heater works as instructions indicate. I would unplug it and let it sit for awhile. The button at the top takes a firm press, the heat indicator will cycle higher and higher and then all the way back to cold after many presses. Disconnecting the power for awhile should reset it to default 78 degrees. Mine is a 25 watt heater, so it will only heat a small tank that is in a room not overly cold. Good luck!

Either not pressing hard enough to move the green LED, or it could be defective.

I have the model with the additional display module. I does get a bit warm. I called PI and discussed this with a tech. He had me measure the OHM rating of the actuator which employs a copper coil and is basically an electromagnet that is in the solenoid the allows power to pass thru the unit. He indicated the some heat is OK.

Mine is doing the same thing. It states the max temp is 190, so setting it at the max should be safe and it operate normally. Has anyone else set there's at the max and it works fine? thanks

You can use the up arrow to "set" the temperature higher, but the heater may not be capable of achieving a higher temperature in your room. It sounds like your space is too cold and/or too big for the heater to handle it. If it runs constantly and never shows a temperature higher than 58, then that is probably as high as it can manage.

It may be getting too hot. Do you unplug it daily when not in use? I don't have this particular warmer anymore due to a puppy I had for a month=) but it was doing it & my new one did it one day & it made me think of my old one. I unplug it when not in use & I don't see it blinking anymore. It definitely warms. Maybe it defective. I'd contact the manufacturer Also, have you gotten it wet=)maybe with all that people release during a massage(electricity+ human aura, things may mix up) Food for thought. I hope I helped!

Sorry I am late responding. I have been out of town for Christmas. It sure does. When you fill the bed, try to come as close as you can to your desired water temperature. The heater is designed to maintain water temperature, not to bring cold water to the desired temperature. It will, but it will bring it up just a very few degrees a day. The last thing is if you are light sensitive, the heater temperature light flashes when it is heating and glows when the temperature has been met. According to the literature, it maintains the temperature with in 1/4 of a degree meaning if it heats back and forth between the 1/4 degree range selected for it. We love it.

Haven't got a clue Todd, never happened to me. Mine has worked flawlessly other that I have to set the temperature to about 72 to get my desired room temperature of 68 degrees.

Hi -the light will come on when the heater senses the water temperature as less than what you have set the heater for. So if you set the heater for 77, and the water is 78 then the light will not go on. Check the water temp. You might also have a detective one, but mine works great.

I had to ask the manufacturer the same question and the reply was "yes, on at 32* and off at approximately 45*" It is interesting that in none of their literature is this mentioned. I'd think that might be something a potential buyer might like to know. I have not verified the temperature range but this is what I was told by the manufacturer. So far however the heater is doing it's job very nicely.

It's possible that your water is already above the temperature that the heater is set for. Either that or it's a defective unit, like the other answer said!

If your elements are still lit up and it stays hot, there must be a problem with it. Mine does neither of those things. I'd return it, I think :).

Thank you for your inquiry. Please make sure that the hot water switch on the back of the unit is turned on. It light will remain lit until it reaches the appropriate temperature.

Flashing lights mean that it is heating. 78 is preset at the factory. Use the up arrow or plus button to increase the temperature. 78 is too cold for most climates. I run mine at 80 in summer and about 82 in winter but I like a cooler bed. Also to minimize the amount of heating, put a thick blanket or comforter across the entire bed to avoid heat loss.

When you turn it on, it will show the last setting you used and proceed to heat to that temp... eg. if you take one of the presets and adjust a couple of degrees via the +/_ buttons to 97 degrees, that's what will be still set next time. You can't set temp any lower than 60 degrees though (or 140F). To get water to 115 degrees, you have to just watch it and remove the kettle when the display shows that temp.

The lcd is green during normal operation. when when the water temp exceeds 1-2 deg it turns red and when it drops 1-2 degrees it's blue. So I guess it's on when it's blue. It's a great heater and the best thing I like is the digital thermometer. I used to buy the cheap one and it kept breaking.

The unit is remains relatively cool to moderately warm but not Hot! I have had the display on for 12 hours straight and no over heating issues occurred. LEDS are cool to the touch.
