As an additional tip, please take time cleaning your unit by descaling it. This will prevent internal scale build up inside your copper pipes on your unit.

I have tried the suggestions you sent me and this is what I've found. the filter is clogged and does have debris on it so i cleaned it with a brush. I took out the flow meter sensor and it was "okay" but sometimes it is stuck when i blew air through it so I did my very best to clean it. i put the filter and flow meter back and alas! Hot water!! I did not know that it was just the issue. from now on i will check on these parts from time to time. the filter serves its purpose. thank you for your help. i appreciate it so much. John :) Tech Support Hello John Smith, Sounds like a good plan. Please let me know after. Regards, Technical Support Team Eccotemp Systems LLC 1-866-356-1992 (Mon-Fri 9am-8pm PM EST) www.eccotemp.comEccotemp John Smith May Gas company said that it is at 9 inches of water column so the gas feed should be good. I will do your suggestions when I get home. thank you John Tech Support Hello John Smith, Good day! We apologize for the inconvenience. The E1 code indeed pertains to Gas. Try tapping on the solenoid valve to ensure that it is not stuck. If the gas company has checked the pressure feed already and is in the right column (8-11 inches of water column) then we have to check the screen filter if it is clogged. Unplug the unit and check all the wire connections on the computer board and check the flow meter sensor too. Make sure that the propeller inside of the sensor spins freely and is not obstructed. The flow meter sensor is the main trigger for the unit's operation. It is located inside the water heater. Just detach the front cover by removing the 4 screws. Then, take out the flow meter sensor and check it. See attached photo for the sensor.
