Tankless water heater should have yearly maintenance that includes cleaning burner parts, with check of ignition parts, wiring, ignition sequence, gas supply, and bleed gas line if needed.
Chances are that your unit needs to catch up on maintenance.
Maintenance can also catch any condensation problems and make venting adjustments so parts are not degraded due to vent issues.
Tankless should also be delimed each year to preserve efficiency of heat exchanger.

Sorry to read about your problem, I hope this helps you out.

your error code, is you have clogged burners, and they will have to be cleaned,
THIS IS A GAS PRODUCT, INCORRECT REPAIR CAN CAUSE A EXPLOSION, AND DEATH CAN OCCUR. IF YOU DO HAVE THE PROPER TOOLS SUCH AS MANOMETER AND LEAK DETECTORS, I SUGGEST YOU CONTACT A SERVICE COMPANY

First shut off the gas,water and power(unplug it) Take off the cover There are about 20 screws above the electrical circuit board . You have to remove all of those screws to remove plate that is covering the burner assembly. The burner assembly has these 3 pins that look like number 7's these are covered with build up and gas can't flow right. That's why you get the c211 error not enough gas. Take a wire brush and gently remove any build up, I also cleaned the thermocoupler which is next to the burners. It looks like a metal pin with a couple of wires coming out of it this was also very dirty. I took a can of air and basically freshened it up It works perfect now. All that you need is a long phillips screw drive and a drill because its about 25 screws the burner assembly has 2 screws all in the back, underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

Good Luck
