dsi flt issue

[dvjones17]

The dsi flt alert for my atwood water heater kepps tripping. I've checked connections and the fuse at the water heater and the pilot will again light. After it reaches temp and shuts off it will not reignite until I pull the fuse and put it back in. Any suggestions? This is a new 2016 Jayflight only on our third trip.

The number one cause of most intermittent ignition issues of 10 as listed by Atwood found in their Service Manual is poor electrical ground;
"CHECK ALL OF THE WIRE CONNECTIONS.
Poor or corroded wire connections cause most of the intermittent problems in water heaters. You should go through and pull all of the wires off any spade connections. Then reconnect them and ensure the connections are tight and corrosion free.
We want to point out two connections often overlooked.
First, check the (green) ground wire of the circuit board. This wire screws down under the circuit board mounting screw. If that screw for the board is loose, you may not have a secure ground.
Second, check the four wire edge connector going into the circuit board. Remove the circuit board. Take a pencil eraser and clean the marks off the connection of the circuit board. Reconnect the four wire edge connector onto the circuit board and then immediately remove it. Look at the edge connection of the board. You need to see four good scratches in the connection. If you do not see four scratches, then you will need to repair the edge connector or replace the wire harness."

Thank you Sir. Cleaned all terminals and it appears to be working now.
