Importance of Status Light
The status light serves as your primary communication tool for understanding your hot water heater’s performance. Monitoring it helps identify various operational states.

Causes of Blinking Green Light
A blinking green status light can be concerning, but it often indicates various operational states of your hot water heater. Understanding these can help you address any potential issues.
Normal Operation
A blinking green light may signal normal operation in some hot water heaters. During the heating cycle, the light blinks to indicate that the unit is actively heating water. This blink is typically consistent and can vary in frequency depending on how the heater is designed. If you notice a steady blinking light, it usually means the system is doing its job effectively.
Malfunction Indicators
A blinking green light can also hint at possible malfunctions. If the light blinks erratically or changes in patterns, it might indicate an issue that requires your attention. Here are some conditions to consider:
- Overheating: If the thermostat is malfunctioning, it may cause overheating, triggering the light to blink erratically.
- Temperature Sensor Issues: A faulty temperature sensor can result in inconsistent heating patterns, causing the light to blink unexpectedly.
- Flame Failure: For gas units, if the flame goes out, the light may blink to alert you of this situation.
Monitor your hot water heater closely. If the blinking persists or worsens, consult the user manual or contact a professional technician for assistance.
