We have a new rinnai tankless water heater running on

Customer Question
We have a new...

We have a new rinnai tankless water heater running on propane.It will work fine for me to bath my 2 an 5 year old and for my husband to take a shower but when I go to take a shower we get an error code 12 and no hot water. The next morning it works fine.

Contractor's Assistant: How old is the appliance? Have you gotten error messages before?

This is a new house and we started using it about 4 weeks ago. And yes we have gotten the message numerous times. We were told to clean the filter since we are on a well but that has not helped.

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

Depends on how complex the fix is. We are quite handed with household fixes.

Sounds like the gas is undersized or the high and low fire parameters aren’t set correctly

Thanks, we'll check both of those ideas. We thought it had something to do with the gas supply.
Plumber: WCohn, Journeyman Plumber replied 7 months ago

You need a nanometer and the piece of paper inside the clear envelope glued to the inside of the front cover. It says how and what to set them at.

Please leave me a five star rating
