Have you tested the power at the water heater and confirmed you have 240v between the two hots?

That is your next step.

You've confirmed 240v at the unit so the supply is correct.
That only leaves the pressure/water flow sensor as a problem or water flow to low to turn unit on.
Diagnostics are on page 9 but there isn't much to check.
