I just had the same prblem and had a gasfitter out yesterday to have a look at mine. He suggested to me to take the front panels off and use a compressor to clean out all the dust that has built up. My filters were clean as they get cleaned every week but as therinnaiguy said it is a overheat safety device.

I used my compressor and blew out all the dust it makes a fair bit of a mess but it seems to be working fine now. Just be careful when u use the air not to directly blow it around the electrical area.

There is also 2 wires u need to disconect u will see these when u take the cover off and also make sure u unplug the the power to the unit.

Hope this helps.

I have a paloma tankless water heater (no sure how old) currently renting (landlord useless). Code says C7 12. What is this?

Probably a flame failure code. This is a Rheem product. Go to the Paloma web page and track down the code. Just google it.

Water heater using too much electricity.

Check if the TP valve is running water, and replace TP valve. Check if there is water leak somewhere
Replace both thermostats and both elements, and then keep temperature turned down.

I have to flip the breaker to the water heater to take hot showers

You need to get the landlord to fix that issue. It sounds like an internal short in the heater.

There is a Reliance 640 dort 40 gallon water tank installed in my bedroom closet. It's a mobile home and I rent. It's bad enough that a home model is in there and is larger then a mobile home water tank,...

Water heater explosions are extremely rare.
I do water heater research including insurance data on water heaters >>> the insurance industry has no reports that I've ever seen of exploded water heaters.
The water heater manufacturers experimented on prior generations, so now our water heaters are safe.
You can turn the water heater off when it is not being used.
You can also set the temperature to a modest 120 degrees and then the water never gets hot enough to cause any problem with the TP valve (drain pipe) or any problem burning you when you use hot water.

If you have a gas water heater, the TP valve will start dribbling water if there is ever a overheating event. So you will see it starting to get bad and then you can report the problem to your landlord

If you have a electric water heater, electric water heater has 3 safety features.
1) The circuit breaker
2) An energy cut-off red reset button located behind the top panel.
3) The TP valve

Here's another solution. Put a metal paint can or metal pot under the TP valve pipe where it comes down to the floor. Do not cap off this pipe.

My last solution is one my friend took when draining his water heater in a rented trailer. He drilled a hole in the floor. Your TP valve should exit the trailer. His solution might not be right for you. But take some photos of the problem and keep them in store in case the landlord refuses to refund the deposit.

Rest well. Every trailer, and every home has a water heater. I worked in the trades for 30 years. I never saw or read of one exploded water heater except the mythbusters video on U-tube (which is entertaining and shows how far a water heater has to be pushed before there is a problem).

My wife and I are renting a house. The landlord told us that the water heater was recently replaced. The hot water smells pretty bad. The landlord says that the fowl smell is due to the anode rod in the...

Hi. Your landlord is correct. Anode rod can produce rotten-egg smell. Ask him if he can replace the "sacrificial" anode rod with "Power" anode rod or zinc/aluminum rod to get rid of the smell. However, you need to decide whether you tolerate the bad smell produced by anode rod or the minimal toxin produced by zinc/aluminum rod.

You can also try to drain/clean the tank first then add peroxide treatment and see if the smell goes away. If you do this method, the smell is more likely to come back if you go on vacation and left the heater unused for several days.

This article explains it better: Why Does My Water Smell Like Rotten Eggs (scroll down to page 2)

Let me know if you need further assistance. Thanks.

RINNAI Heater 1001FT Gas heater; was wondering if water required?

It shouldn't give an odor at all unless it hasn't been run a lot or cleaned. Rinnai recommends blowing compressed air through the front grates once a year. The pan is to catch condensate from the venting system. Hot flue gases contain moisture, which is a byproduct of burning propane. When this hits anything below 212 degrees, it will condensate and collect in the pan. The heat from the unit evaporates the water, thus making it a good system of condensate disposal. However, additional water can be added daily if you have problems with dryness in the air. The only other thing that can cause a bad odor is a compromised heat exchanger. You should have it checked, and if you don't already, have a CO detector in the room
