Water dripping from the bottom of a heater typically indicates an internal leak or rain water entering through the exhaust vent. If you have this problem follow these steps:
- Shut off electrical power to the unit either by unplugging from the outlet or shutting off the switch or circuit breaker the unit is wired to.
- Shut off cold water supply (also turn off hot water if you have isolator valves1)
- Drain water from unit using either isolator valves1 or black plastic drain plugs2 on bottom of heater.
- Contact a Noritz Service Representative. To find a servicer please visit: http://www.noritz.com/home-owners/find-a-servicer/
Following these steps will minimize the chance of electrical damage within the heater.
