Our new 750w is now bubbling and making a white foam bubbles in the center.. it's been raining and warm. It should be off - built in thermostat.

Mine failed within the first month of having it. If you can send it back and get your money!

Your heater will kick on and off during warmer days and as water changes temps. White foam and bubbles are a normal issue with water temps changing..all is fine no worries

Ours isn't circulating either. We filled to the water line and have a slight bubbling, but it barely works. Suggestions?

We've not had this problem. I'm sure I don't need to say it, but perhaps a good filter cleaning would help. Maybe there's some manufacturing residue on it or something like that. I hope you're able to resolve this issue because it truly is a great heater.

Ours is working okay, though we haven't used it that much lately. I would recommendd calling the manufacturer for help.

sorry I missed this, I never got a question from Amazon before, bubbles on bottom, and make sure its dry and covered on the off season, mine died after 3 years

The only thing I can think of is incorrect wiring or you have it hooked up to something that is trying to draw more amperage than the unit can handle and it's tripping rather than switching anything on. Perhaps it's a protection circuit? Have you tried hooking it up to something that draws lower power? I had mine wired to a heating pad as a warming pad for a while to start seedlings. Then I wired it into a home made aquarium type heater. I don't get any 'alarms', my unit works perfectly every time. I'd have to see how you wired it and what it's wire to in order to help. Sorry.

Suggestion: my heater did the same thing and I found that the front 'dome' and inside [where the blower motor is >> you will have to take off the outer cover], had a minute layer of dust that the unit somehow sensed. I used a dust brush, clean paint brushes, and some compressed air and blew what seemed miniscule particles away... IT WORKED. [my indoor parabolic quartz heater had the same problem which led me to try this....].. GOOD LUCK

I had the same problem and was told by their customer service that a bad batch of thermostats was installed in some units. They are sending me a new thermostat, which i guess i will install myself. I also have had two issues now with the on/off switch not working properly. I am sorry I bought this unit.

I suspect it's getting too hot and shutting off as a safety feature, then turning back on after it cools down. I would go down in wattage. I had to get another smaller dome and a regular household bulb in addition to this keep the heat up in my terrarium.

Owners manual indicates it is dealing with very impure air. I would put it on a table top for a few days and see the red flashing stops. If it does you may have it in a draft prone area or have dusty floors or both. If I clean my floors around the unit sometimes it goes yellow. Might need to clean the Dust Sensor Filter w/ soap and water. Read the owners manual.

Andrea, sorry, I returned this product because it would bubble if you put heat on it....don't know what to tell you, maybe you can call the company and they will have a better idea how to help you.

When I first got mine, I set it up in the kitchen under some lights, filled the water tank, and then turned it on to confirm it worked. I ran it for a few minutes and then unplugged it and carried it to my room. I noticed that it wasn't blowing out much mist. Like you are noticing now. I proceeded to empty out the basin and try again, and it worked like a champ. See, in carrying it down the hall with the water tank full, when it gets jostled around with the valve open, more water gets into the basin than should be and the ultrasonic platter can't work through the higher levels of water. Just empty out the basin, put the water tank back on and turn it on. Also, the more you turn the knob, the more mist comes out. Turn it until it stops turning, that's full power.

Yes, we have had the exact same problem. I'm guessing this relates to a problem with the water sensor or the electrical connection between sensor and indicator light.

make sure the intake is clear. mine gets algae and 'junk' in it and it need cleaning regularly.

The sensors might be dirty or perhaps the unit is too close to a vent or air source. I took the front panel off of mine and blew on the sensor then relocated it slightly. It hasn't happened since.

Are you using it as a floating device or sunken device. Mine is on the bottom of the pond. NC climate is pretty mild compared to some. If you are floating it unit might be effected by air temp.

Hi,Mine first did that when it was first installed. The temp was set to high. I unplugged the unit and not turn it back on until the next morning and it has been great since then.
