Troubleshooting An EC Error Code On A Fogatti Tankless Water Heater

Question

Question:

It worked for the 1st week and then an error code Ec appears. The gas in at mid level, the water pressure is normal. The owners manual does not have Ec thus I went through the standard trouble shooting on the unit but was no successful. Any suggestions would be helpful.

The EC error code mean that the Fogatti Tankless Water Heater # LSB64FR tried to start the pilot light and was unable to due to low gas pressure. You'll want to have a licensed technician check to ensure you have 11"WC at the unit. If you aren't getting 11"WC at the unit you could have an issue with your propane tanks or regulator. If this does not solve your issue please reply back and we can keep troubleshooting.

My new heater is suffering from an e1 error. I have a full tank with a regulator… what’s the best way to ensure proper propane pressure? Thank you.

@IE Fogatti placed little plastic caps inside of the water and gas inlets (red/blue) that are small enough that you could still thread on your supply lines. I recommend shutting off the gas bottle and turning on the stove to clear the lines and then remove supply hose to check if that cap is still in there. I've seen this happen quite a bit so it's usually my first step. From there you'd need to check the gas pressure after the regulator with a manometer to see if it needs to be cleaned or adjusted. This I typically pass off to a certified tech because it can be dangerous working with gas and the tools needed are pricey for a one time use. A local gas or HVAC company can easily check this and adjust the regulator as needed. It's also important to check that the propane tank valve is open and that you don't have a shut-off valve anywhere in line to the water heater that could've potentially be turned off and is prevent gas flow to the unit. A lot of people will put in quarter-turn valves for both gas and water lines right by a point of use so that it can be shut off and still allow the rest of the appliances connected to the system to function.

My pressure was good but still has the Ec code. What now?

@Jayme If the gas pressure is fine but you're still getting an EC error code then the ignitor could be faulty. For a replacement you'll have to reach out to Fogatti directly.

I had it checked and it has the appropriate pressure coming to it. Still get the code though. Any ideas?

@Jt You most likely have an issue with the ignitor, but at this point you'll need to involve Fogatti because they don't offer replacement parts for us to distribute.
