Troubleshooting Steps
When your Atmor tankless water heater doesn’t turn on, follow these troubleshooting steps to identify and resolve the issue.
Check Power Supply
- Inspect the Power Source: Confirm that the unit is plugged into a functioning outlet. Test the outlet with another device to ensure it works.
- Examine the Circuit Breaker: Check if the breaker for the water heater has tripped. If it has, reset it and see if the unit powers on.
- Assess Wiring: Look for damaged or frayed wires. If you find any, contact a licensed electrician for repairs.
- Verify Minimum Flow Rate: Ensure the water flow meets the manufacturer’s minimum requirements, usually around 0.5 to 0.6 gallons per minute. Low flow can prevent the heater from activating.
- Check for Clogs: Inspect the inlet filter for debris. Clean it if necessary to maintain proper water flow.
- Examine Incoming Water Temperature: Make sure the incoming water temperature is within the acceptable range, typically between 35°F and 60°F. Extreme temperatures can affect performance.
Safety Precautions
Handling your Atmor tankless water heater safely ensures efficient performance and personal safety. Always prioritize these safety measures.
- Turn Off Power
Always turn off the power supply before performing any maintenance or troubleshooting. This prevents electric shocks while working on the unit. - Inspect Wiring
Regularly check wiring for fraying or damage. Damaged wiring can lead to malfunctions or potential electrical hazards. - Use Recommended Tools
Only utilize tools that the manufacturer recommends for servicing your heater. Using improper tools may cause damage or void your warranty. - Maintain Clear Access
Keep the heater’s area clear of debris and flammable materials. This reduces the risk of fire hazards and allows proper airflow around the unit. - Regular Maintenance Checks
Schedule regular maintenance checks to identify potential issues before they escalate. Routine inspections help ensure optimal performance and longevity. - Temperature Settings
Set the thermostat to a safe temperature, ideally below 120°F (49°C). This prevents scalding injuries while ensuring adequate hot water supply. - Be Aware of Leaks
Regularly check for signs of leaks around the connections and fittings. Address any leaks immediately to avoid water damage and maintain efficiency.
By following these safety precautions, you can ensure your Atmor tankless water heater operates smoothly and safely.
