Electric hot water heater not working
I typically keep my electric water heater on while camping so I can have hot water whenever it is needed. Today mid-day I went to wash some dishes off in the sink and the water was not warm. The switc...

So with propane side working you can rule out MAIN DC Fuse,'thermal fuse', t-stat & ECO cause both heat sources use same items
So check the 120V AC circuit breaker for your electric element power (CB in MAIN AC Panel) and see if it tripped.
Otherwise you need a voltmeter to check components
DC Voltage goes to the Dual Switch ON/OFF panel
DC for electric then goes to circuit board via WHITE wire (use voltmeter to check that you have 12V DC at connector on circuit board with Electric Switch ON
Then have to check that you have 12V DC coming out of connector on YELLOW wire with electric switch ON AND water temp below 110*F so 'heating' circuit is active.
Then you would need to check that electric element is getting 120V AC---have to remove cover on backside of water heater inside the RV.
DC Relay and element under that cover
DC Relay feed from YELLOW wire (cold water temp) and triggers 120V AC to element
AC wires from relay could be bad
Element could be burnt/shorted
Electric ON/OFF Switch could be bad
DC at/from circuit board could have bad connections/dirty contacts
Electric circuit on circuit board could be bad
Voltmeter and trace DC and AC voltages
