I have a Richmond gas water heater that is only a year or so old. I have not water in the tank but can only get hot water to our kitchen sink and intermittently to the bathroom sink. None to the bath tub.. It started where we had rust build up in the valve of the tub that wasn't allowing e ought hot water to mix with the cold. Fixed that & it was working fine. Then all of a sudden no hot water at all to bathtub, or bathroom sink. Then it was intermittent for bathroom sink and kitchen. Now just kitchen. Any ideas?
The water inlet to the heater must be plugged.
SOURCE: On demand, tank less water heater
THE WATER IS RECIRCULATING IN THE UNIT. MAYBE CAUSED BY THE ACID. TRY INSTALLING A BACK FLOW PREVENTER
SOURCE: No water pressure in bath tub after turning off hot water heater
It could be back flowing into the hot water heater tank which is not full because of the leak. Even though the valve is closed on the cold water entry side, there is probably no valve on the exit side. That is how it is returning to the tank.

SOURCE: New Richmond tankless water heater C8 error
I think error code C8 is #13
It has to do with air quality, lack of sufficient air, or lack of venting or dirty air filter.
