If the gas supply has been interrupted the water heater will display er-
ror code 11 or 1. Turn off the power to the system, wait 10 seconds
before turning on again.
Check isolating switches and electrical connections to ensure everything
is turned on.
Check the fuse or circuit breakers at the meter box. Repeated failure
of a fuse or tripping of a circuit breaker indicates a fault which must be
investigated by a licensed tradesperson.
It's normal for the Cold Water Relief Valve to discharge a small quantity
of water through the drain line. If water is discharging continuously
there may be a fault with one of the valves, contact your installer to
discuss.
