They are submersed elements...need water to absorb heat generated.
Tests: 12V DC Voltage
With electric switch ON
Should have 12V DC on WHITE wire to circuit board (top connector)
Should have 12V DC on BROWN wires from circuit board (bottom connector) and to circuit board (top connector) ---thru thermal fuse & t-stat
Should have 12V DC on YELLOW wire from circuit board (bottom connector)
Should have MILIVOLT signal on RED wire from circuit board to/thru ECO and to gas valve solenoid (bottom connector)
Other tests: 120V AC....switch OFF
Check for continuity between the Black and White wire terminals
6 point 1 1/2" socket to R&R element.....tank empty!
No Continuity...element BAD
Check for continuity between White wire terminal and element flange.
IF you measure continuity then element is BAD
120V AC....switch ON
Backside of water heater under protective cover 12V DC on Yellow wire to 'relay'
120V AC on BLACK wire to element-----WHITE wire to NEUTRAL Buss in Main AC Panel
