First check the power supply (circuit breaker). If power is present, the thermostat or heating element may be faulty. Contact a professional for replacement.

Turn off power supply, close cold water inlet, open a hot water tap to let air in, then open the drain valve at the bottom of the tank. Collect water in a bucket.
