Gas water heater not turning on
Hello and thanks to al ln in advance! Dry camping for first time with new trailer and could not take a hot shower? I smell the propane at the water heater and it tick tick tick ticks and nothing. I...

Good grief........
Your spark electrode is double duty.
Provides pathway for High Voltage Spark to ignite the gas
THen it proivides pathway for the 'rectified' current produced by the flame burning that is used as the flame priving signal ----just milliamps but enough for circuit board to sense that dc current
W/O circuit board receiving that signal it drops DC to gas valve so raw fuel desn't accunulate
You have gas flow (cause you CAN lite it with BBQ lighter)
You have Spark cause you can hear it CLick, CLick, Click
Circuit board is sending the DC to gas valve/spark electrode and is locking out the operation after 3x failed attempts (Fault Light comes on)
*Spark electrode gap ---too narrow/too wide ---no ignition (1/8" - 3/16")
*Spark Electrode wire connection...MUST be clean and tight. High Voltage can flow but the milliamp current can easily be stopped
*Spark Electrode MUST be engulfed in main flame when it ignites otherwise milliamp signal will not be sensed
*Spark Electrode must be clean...no soot.carbon----clean it using emery cloth
*Flame Spreader Plate (round disc) at end of burner tube must be squared/parallel with end of burner tube to properly spared flame out when it ignites
*Grounds.......MUST have good clean/tight grounds
*Connection at/on circuit board must be clean/tight
