If the heater is not turning on, but there is a display on the remote, the filter might be clogged. Debris in the pipes from installation can clog the filter. Another possibility is reversed water connections: cold water supply connected to the hot water outlet, hot water supply line connected to cold water inlet.
If there is nothing on the display, verify that the heater is plugged in, the remote is plugged in (no damage to the wire), the outlet is receiving power, and the circuit breaker has not tripped.
