- Flushing Cycle: If your unit is set to perform regular maintenance, such as flushing, the status light can blink during this process.
- Power Interruption: An unexpected loss of power might cause the light to blink when the unit is turned back on while resuming normal operation.
If the blinking green light persists or changes to a different color, consult the manufacturer’s manual for specific guidance. Keeping track of system behavior allows for proactive management of any potential issues.
Troubleshooting The Issue
The blinking green light on your water heater can be concerning. However, with the right troubleshooting steps, you can determine the cause and address the issue.
Step-by-Step Guide
- Check Power Supply: Ensure your water heater is plugged in and receiving power. Inspect the circuit breaker for tripped switches. Reset if necessary.
