FFL ? sounds like a flow error on the control panel. take the filter out and see if it goes away. might just be a dirty filter or the pressure switch is not working.

Anytime the heater is reading the water temp to be above what it actually is, especially 126, the problem is the Thermistor, or Temp Sensor, for the heater. This is a very easy part to replace. The Thermistor is located on the manifold, on the left side, between the top two bolts.
Sorry this is a late response! Hope that it helps!

Your EO4 message tells you you have a fan problem. So ether your fan is diying wich you would hear or you have a bad presure sensor in your exaust. A new fan is a little pricey but the sensor is reasonable for heater parts. I can't be sure but I believe it ether screws onto or into your exaust and it just plugs on to your control board. If your sensor is going bad their is a reason and this should be addressed. It should be in your by-pass or your gas pressure. But as far as a new heater, not untill you have water coming from the cabnit. It is sometimes easer to sell new than keep up with new, Good luck let me know how you do.

This is a problem with your thermister (heat sensor) You will find this on the left side of the water manifold about half way down. I'm not sure but I think it is a small tube that slides into the manifold and if you follow the wires back to the board it just plugs in. The part is reasonable priced for a heater part and very easy to install. Good luck.
