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

Hi Larry, it looks like you ain't got a cloue on how this thing works! Just follow instructions and take the machine off the heat after it stops gurgeling.- Everything will be alright...the General...

you might have to play with the regulators...i noticed when i have the burners off and turn the tank on that you will hear a click and i think the pressure needs to equalize before trying to start it. it happens when i change tanks and i usually wait and then it gets hot, if i start it right away i have trouble getting a high temp. also watch the wind, i have my door face the wind and play with the dampners on the sides. i have been using mine in 10 degree weather and it is heating just fine. as far as damage i didnt experience that.

I haven't experienced this. Is the water level getting low or have you noticed that the "Steam Ready" indicator light is off (meaning that you have used up the available steam and must wait for the unit to build up steam) ? Other than that, I can't think of a reason for the situation you describe.

We've had our 2 heaters now for a year and I think they come out together. Keeping the air from getting dried out. Need to fill the water once a day.

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

I just bought this unit in December and I have the exact same problem. I love the unit. It is on my bedroom carpet so I am going to try to put a mat underneath it to see if that helps and I will try to change the water level a bit as another person suggested. My guess is that the water sensor works well and the system needs to be level. Someone else told me to put it up at the highest setting and that may help. I really don't want to have to replace it and its too late to return. It really is an awesome unit. Looks great too

So most everyone sees these bubbles as a problem? I miss them having switched from a pair of simple power filters. I have the eHeim intake on one end of the tank and the output dumping down into a bubble wand for a long strand of lots of bubbles. The fish - tetras, mollies, platys, loahces - tend to congregate on the intake side of the tank. Not cool?

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.

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.

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.

We haven't had the fan long enough for me to comment on this. Also, its is winter here and it isn't humid. Sorry I couldn't be of more assistance.

Ours is working fine. Did you put in too much water? The different water levels are a bit tricky to see.

I spoke to Watts about this issue. They said the noise is related to water passing through the membrane. I am still looking into it, but the noise is not constant in our case.

It could be the automatic thermostat cycling on and off. This unit is not designed for continuous heat output.

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.

Probably an air bubble in it rock it and see if that helps if not take the top off and put it back on and prime it! Mine is so quite I wonder if it even works at times.
