Model number would help!
Does the light on the switch come on when you first turn it on?
No could mean a blown fuse in the DC power panel, a blown thermal fuse in the water heater hidden under a piece of tubing, open thermostat, or open ECO.
The thermostat, ECO and thermal fuse can be checked with Ohm meter.
Power can be checked with DC volt meter or test light.
