Troubleshooting E.C Error Code With Fogatti RV Tankless Water Heater

Question:

Ive had the unit for over a month. I have a full tank of propane the stove lights. Double checked the gas plug was removed. I have 12v running to the unit and while running the water. Also verified the fuse is good and the switch is in the on position. Please help. I just received a new mother board and im still having e.c on the controller.

Sediment build-up may also causing you to continually receive the E.C error code on your Fogatti RV Tankless Water Heater # LSB44FR.

Since your unit is pretty new it is unlikely but I would try and rule everything out first before replacing the unit or buying anymore replacement parts.

You also might also consider installing a Camco RV and Marine Disposable Water Filter w/ Hose Protector # CAM40043 which will remove aluminum, bacteria, bad taste, cadmium, chlorine, fungus, heavy metals, hydrogen sulfide, iron, lead, mercury, mold, odor, cloudiness, and sediment from your fresh water.

Finally the last thing you can try if you haven't already is a hard reset. To do this, simply cut the power to the unit by removing the fuse or disconnecting the positive power wire at the battery or unit.

You'll want to wait about 15 minutes after this before reconnecting power and check to see if the issue persists.

If yes, then I recommend having a certified professional come and check your unit out. Being as your unit is still pretty new you're still be under warranty.
