Rinnai r42 - Rheem RTG-53PVN Indoor Natural Gas Tankless Water Heater for 1-2 Bathroom H

I could not find r85 model on rinnai website. There is a troubleshooting guide on rinnai website. 100000652-Troubleshooting TWH Diagnostic Codes.pdf (rinnai.us) It may help to find a solution.

No, there isn't an Error 09, but there is a E19.

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,

I left Rinnai only about a year ago at a levle of State Service Manager. I had been asking for service manual for for many, many months. Basically as far as I am aware there is not a service manual for the WG. If you google Rinnai Infinity 26 manual you can get a PDF from the Rinnai NZ sales site but his dates baack to 2003. Unfortunately there are major changes to some of the components but it might be better than nothing. Just don't use part numbers, and you might find bits to check that now have voltage and resistance differences. Send a message to Rinnai complaining, I encouraged people to do so even when I worked for them!

Just joined fixya and am a Rinnai service manager in Australia. Is this still an issue?

Power outage will reset Rinnai unit to that temperature. Read manual for more info.

curios to find out if you had any help on this subjuct at all?

you can go to the rinnai web site and down load this,, they are available on line,,
