  If hot water is not available when you open a fixture, ensure the unit has a 240V 50Hz power supply. If you're using a remote controller, check if it's turned on. Also, verify that the gas and water supply valves are fully open. Make sure the filter on the cold water inlet is clean and the hot water fixture is sufficiently open to draw at least 3.0 l/min through the water heater. Finally, check if the unit is frozen or if there is enough gas in the tank (for propane).
