Do you have a question about the XTP PRO Series and is the answer not in the manual?
Questions and answers
Power is on water is flowing contacts won't engage heater is nine months old what could be wrong
If the EemaX XTP PRO Series heater is not engaging despite power being on and water flowing, the issue could be due to one or more of the following:
1. Water Pressure: The water pressure may not be within the required range of 40–90 PSI. If the pressure is too low or high, the unit may not operate properly. Check the water pressure and ensure it meets the specified limits.
2. Air or Debris in the System: Air or debris in the water supply system can prevent proper operation. Ensure the water supply valves are open, and purge the system to remove any air or debris.
3. Clean Water Supply: The heater must be supplied with clean, potable water. Check for clogged filter screens, y-strainers, or pre-filters and ensure a clear water supply.
4. Flow Rate Below Minimum: The flow rate might be below the minimum required for the heater to activate. Verify the flow rate matches the model's specifications.
5. Component Failure: A component failure could prevent the unit from engaging. Check for any notification codes (if applicable) and refer to the corrective actions outlined in the manual.
By verifying these factors, you can identify and address the issue.
