Call Rheem for a new unit. They problem will never be fixed. They have redesigned the unit. It is now RTG-95DVN a self contained venting unit. Mine was worked on several times over two years and much frustration before they finally replaced it.

Rinnai RL94i - Produces hot water for 3 minutes, then stops


I just had this exact problem. It kept getting worse until we had no water. Our Rinnai tankless hot water heater started the same way though, with hot water for a few minutes and then would shut off with an error code 10. We just had to shut the hot water off and then back on, wait a minute or so and we had hot water back for a few minutes. Our unit would come on with a loud vibrating noise and remain until it shut off with an error code 10 (air flow fault). The solution was to remove the blower fan and blow out the squirrel cage. Ours had moths in it. We also vacuumed out the fan housing. Be careful to mark any wires you disconnect and take pictures before removal. Our unit is now almost silent when it comes on and supplies endless hot water.

Takes 4 minutes for hot water to reach bath room


its normal with long distance on a tankless witout a circulating system to keep constant hot water because the water heater is always off untill u turn on a faucet then it has to heat up the water all the way from the heater to ur faucet thats what conserves energy not running all the time untill u turn it on. U could install a circulating system but now u have that cost and something running again to cost u money to keep hot water where u want it win lose situation

Hello, I have a 50 Gal. Whirlpool water heater (Model # EE3J50RD045V) and have problems with running out of Hot Water after only one shower! Right now I've killed the power, turning off the water...


Hello. One of your heating elements is probably burned out. You should have two access covers on the heater.One near the top and one near the bottom. The bottom one is usually the firs to go because of water deposit build up. The fix is quite easy however the risk of electrocution is evident. If your fairly handy it's a matter of TURNING OFF THE POWER, draining the tank and removeing the element. If it's bad it may show signs of bulging or swelling. If you listen at the access covers while the heater is running you may hear the good one working and the bad one will be silent. The parts are available at plumbing supply stores. building centers and some hard ware stores.

Sometimes the hot water just goes cold


Here are a couple things to look for:

1) flashing burner light - a flashing burner light indicates the unit is getting an error code
common error codes:
A. continuous flashing - ignition failure or abnormal combustion; look for visible water in the machine indicating a leak, check gas pressure, debris or buildup on flame rod/igniter plug, or clean unit with compressed air
B. 3 flashes - error 16, abnormal outlet water temperature; typically this code indicates you'll need to descale you unit
C. 4 or 5 flashes - exotic error codes; you should contact Noritz technical support to deal with these codes

2. If there is no flashing code, try increasing the hot water flow. In the summer time you typically use less hot water; this can result in intermittent operation of your tankless heater. Increase water flow by either: A. cleaning your showerhead and removing scale deposits B. widening your flow restrictor C. Remove your flow restrictor in the showerhead

3.If none of these resolves your problem, you probably have debris in your flow sensor. Contact Noritz technical support for a walkthrough on removing debris from a flow sensor.

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.
