Safety first
- DANGER: Shut OFF power to the water heater before draining water to avoid risk of shock. (p.23)
- CAUTION: For your safety, do NOT attempt to repair the water heater or any of its parts. Refer any repairs to a qualified service technician. (p.22)
- Fault codes should only be used to help identify components which require testing. Never replace a part based solely on a fault code. The control can generate a false fault if the right conditions exist. (p.28)
From the manufacturer's manual for this series.
