SOURCE: noritz tankless water heater gives error code 11

This worked for me in the same situation. There is a filter inserted into main gas/ water control valve that senses water flow restriction. The sensor is connected to the gas valve. If it senses inadequate water flow it tells the gas valve to shut down so the water in the heater won't boil. Very expensive part. If you do find the filter clogged, a sediment water filter shoud be install on the inlet side of the water piping.

SOURCE: hot water coming out of overflow pipe on my vulcan everhot water

Assuming you are talking about the temperatur/pressure relief valve, it is stuck open.

1. Turn off gas or electric to water heater
2. Close water supply to water heater
3. open hot water faucet on nearest fixture to depressurize hot water system.
4. close tpr valve (you may have to push in on the center spine. It may be resistant to closing from sediment. If so, opening and closing several times may solve that issue.

Once you get the tpr valve closed, close the faucet and open the supply valve. If the tpr stays closed, go ahead and turn on the gas/electric and re-light pilot and turn on control etc.

If the TPR blows again, you will need to replace it. YOu can buy a new one at any plumbing supply store. Shut down the heater again, drain a bit of water out using the valve on the bottom of the tank. there is probably copper pipe connected to the TPR valve which you may have to cut or maybe can just unscrew. The TPR threads out of the tank, install the new valve (make sure to use pipe dope or teflon tape.

SOURCE: Tankless water heater (Paloma) Has C2 11 error

I had this problem with the C2 11 error code. My unit is 1.5 years old. I called Paloma and they emailed me an 11 page document to clean the burners. I am not an HVAC but I got the feeling that's who the instructions were for. Very difficult but you can do it if you're handy. You basically take apart 1/2 the unit, be carfull not to lose any screws and label all the little brackets that come off. It took me 2-3 hours to get to the burners. I used a can of air (for keyboards-electronics) to blow on the burners and clear any build up. After putting it back together (carefull to make sure the 3 gas tubes make a seal when re-installed) the unit works. I did this today so I'm not sure the unit will still work in a week/month. I am dreading having to do this every year to keep the unit running.

SOURCE: My Paloma tankless water heater flashes C2 11 error code

I just had the same problem and I fixed it in about an hour or 2. First shut off the gas,water and power(unplug it) Take off the cover There are about 20 screws above the electrical circuit board. You have to remove all of those screws to remove plate that is covering the burner assembly. The burner assembly has these 3 pins that look like number 7's these are covered with build up and gas can't flow right. That's why you get the c211 error not enough gas. Take a wire brush and gently remove any build up, I also cleaned the thermocoupler which is next to the burners. It looks like a metal pin with a couple of wires coming out of it this was also very dirty. I took a can of air and basically freshened it up It works perfect now. Email me with any Q's at Mario@myredr.com Good Luck All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

SOURCE: richman gas lp tankless hot water heater. used for

I had the same problem with my Paloma a year and a half after installation...contacted Rheem\Paloma\Richman customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.

Install continuous flow hot water system


I dont know if any tankless that have that installed.
Because as soon as it detects water movement it starts heating and if you continuous movement it will heat all the time. If that happens then something is going give and it wont be pretty. With a tank type water heater it just recirculates back to the tank and get reheated as needed.

The everhot water system is not working


check the information on the heater. They do not make a an EVER HOT or let us know if its gas or electric. If its gas you need to re light the gas on the side where the controler is at.

Hi, our recently installed everhot 20 continuous flow is anything but continuous, well, not hot anyway. Sometimes it works fine, other times all we get is cold water that feels like it is starting to get...


If you installed yourself call the support number from the owners manual. If you had a professional do it call them and tell them to fix the issue. This is not normal. If they don' t contact your states contractors license board and get their bondong company info and call the bonding company. When they get that call they will fix it. There are way to many variables to try and TS this issue.

Code 11 01 - Hot Water Heater Kicks Off


if you have build up in the heat exchanger it will cause the unit to use more gas to heat your water, if the gas line isn't sized properly then your going to kick the error codes off. it sounds like you have two problems, first you have build up in your heat exchanger and it needs to be flushed and second you need to get a bigger gas line to it

How to correct error code C-7 on my RTG-74PVN Rheem Pronto


I had the same problem and called the manufacturer. The error code C-8 was followed by the number 76. They told me to disconnect the thermostat/digital display from the main unit. This was fairly simple to do by removing the front panel. The unit works steady now without shutting down after a few minutes. The help desk told me that the main circuit board needs to be replaced for the unit to work with the display and that they would mail me one asap. At least we have hot water again.
