DSI Atwood propane only water heater
Hello. We fired up the Atwood this morning via a DSI switch in travel trailer. 20 minutes later hot water aplenty from the 6 gallon tank. Left switch on and left for awhile. Returned and no hot water ...

At anytime did RED light come on?
IF ECO (Energy Cut Off ---high temp t-stat OPENS if water temp reaches 180*F) does open it will cause the FAULT Light (red light) to come on.
Fault light will STAY on until water temp comes down below 150*F and YOU reset it (to reset you have to turn switch OFF wait 30 seconds and then turn it back ON....ECO will CLOSE when water temp cools down)
So IF no Fault Light.......ECO didn't OPEN (t-stat OPENS at 140*F)
Fault Light will also come on when burner fails to light off and prove it lit.
Control module will make 3 attempts to light main flame/have it prove t lit and then 'lock out'
Again RED light would be ON and you have to reset it
Pull connector on control module....check that pins in connector are not bent and clean contact surface on control module with a pencil eraser.
Then check that spade connectors on t-stat (brown wires) and on ECO (red wires) and on gas valve solenoids (red and black wires) are making a clean tight contact.
Rotate t-stat and ECO by hand back/forth checking that they make good contact with tank wall.
While watching the burner/sparker have someone turn switch ON (with water cold)
You should hear a click at solenoids and hear/see strong sparking at electrode
Flame should ignite and it should engulf the end of electrode turning it red
Spark GAP should be 1/8" and be directly in path of flame
