Rinnai R85 starts to warm then stops and blinks 61??


I went to the Rinnai website and this is what I found for error code 61.
Error Code 61 Problem: Fan failure
Solution: Measure the resistance on the fan motor, check the damaged or loose wiring and connections. Make sure that the fan spins freely.
Sounds like either your fan is broken or something is keeping it from spinning freely.
Hope this helps.

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.

Our rinnai R94LS will shut off after running several minuets and shows error code#10. I'll turn it off for several minutes and turn back on, run system for several minuets and it will shut off again and...


Tankless computer is not working.
Error 10 is blocked flue or inadequate air supply. Or failed PC motherboard, or failed sensor etc.
Get more fresh air to unit. Check if bird built nest on flue pipe. If flue exits side of house, look for obstructions nearby that can slow the exit of poisonous vent byproduct into the air you breathe. For example trash cans and boxes or parked car etc.

Call service technician who is qualified to work on tankless computer. This will be a well-seasoned veteran of computer technology and plumbing expertise ... a plumber who knows how to fix computers lol.
This person will catch unit up on required yearly maintenance, and check specialized operation conditions needed for tankless computers to function properly.
If tankless computer is older than 5 years, then compare it to your 5-year old laptop, and assume same level of glitches and problems.

Rinnai 2532 error code 10


Error Code 10 Problem: Reduced or no air supply to the water heater or there is an obstruction in extracting the flue gases out.

Solution: Make sure that the recommended Rinnai venting is used, there is no obstruction in the venting system, no reduction in diameter and lengths are per instructions. Also make sure that nothing blocks the venting system or fan, and that dip switch and condensation collar are set properly.

Good luck,

Marty

How do I turn it on? I press the "on" button and


The manual says:
http://www.coinwash.com/temp/rinnai.pdf

"For the name of the Authorized Distributor or Installer nearest you, please contact your local HVAC dealer or gas service technician, visit the Rinnai website (www.rinnai.us), call Rinnai at1-800-621-9419 or write to Rinnai, 103 International Drive, Peachtree City, Georgia 30269"

Manual says that the remote is for setting temperature.
When you turn on hot water spigot, tankless water heater will heat the water to the set point temperature.
If water heater is not set up to use remote, then tankless unit will heat to 140 degrees F.
"With the MCC-45-4US remote control installed the water temperature is adjustable from 96
to 180°F. The water temperature cannot be set to a temperature other than 140°F
without the use of the MCC-45-4US remote control unit. If you require a temperature
other than 140°F you must install the MCC-45-4US remote control unit."

"Error messages are displayed on the remote control units, simplifying service calls."

Page 9 of manual shows hot to set temperature using remote.
Water taps must be shut off to set temperature.
Circulating pump must be turned off.
"Simply press the H or C button until desired temperature is displayed"
"green in-use indicator will display"

If your unit is not working, the manual says to contact local plumber.
Fixya has specialists who will talk to you by phone about your problem for a fee.

An error code of 12 on your heater means a flame failure has occured. It could be the following: Flame Rod dirty, Obstruction in burner, improper gas pressure, or a bad ignitor board. I am suggesting you get a technician who is familiar with Rinnai products to check out the above items.

Piping of these heaters in tandem is critical. Specified by Rinnai in their design manual, the cold water should be piped to both water heaters with a back-flow presenter installed before the first heater. The hot out piping should be "Tee-d" together and going to your hot water needs.

If piped as per the manual, try turning the water off to only one of the units. Turn on a hot water tap and see if the unit stays on without interruption. Then try the same on the second unit. You may find that one unit has a bad flow control, which is shutting off the flow of water.

You can get more technical help y contacting Rinnai direct at 1-800-621-9419 ext. 207.
