I've got a Rinnai tankless water heater that keeps tripping…

Customer Question
Good morning. I've...

Good morning. I've got a Rinnai tankless water heater that keeps tripping offline. I reset the on/off switch and after about two minutes, the water gets cold. Is there any simple troubleshooting for this problem?

Contractor's Assistant: How long has this been going on? And how severe is the problem?

It's been going on for about a day now.

Contractor's Assistant: Do you plan on doing the work yourself?

And, the "Priority" light keeps coming on. What does that mean?

Contractor's Assistant: Anything else we should know to help you best?

Not that I can think of.

Ok, Wade.

Go ahead. It's a model RC98HPe. Serial number 10.02-000257. First two fault codes are 25.
Plumber: WCohn, Journeyman Plumber replied 6 months ago

That is due to a clogged condensate line. Most likely frozen.

Plumber: WCohn, Journeyman Plumber replied 6 months ago

Do you know which line is the condensate drain?

Ask Your Own Plumbing Question
Customer reply replied 6 months ago
No, I've never messed with the thing. It's below freezing here in Virginia Beach. I'm guessing the condensate drain is frozen.
Plumber: WCohn, Journeyman Plumber replied 6 months ago

Can you upload a picture of the piping below the unit?

There’s an add files button. We can do it via phone call if you accept my offer

Customer reply replied 6 months ago
No thanks. I'd like my money back. You've already charged $5 and another $33 that I didn't authorize to my card. The $5 was bad enough.
Customer reply replied 6 months ago
I didn't know that Rinnai was outsourcing it's customer support to a third party. No thanks.
