In many cases, the answer is yes – you can clean the main filters during tankless water heater maintenance. Both the inlet water filter and burner or heat exchanger screen can be cleaned to remove any accumulated deposits or debris. However, it is important to note that not all models allow for filter cleaning. Some tankless water heaters have non-removable filters, requiring replacement instead of cleaning.
Steps to Clean the Filters
If your tankless water heater has cleanable filters, here are some general steps to follow for filter maintenance:
- Shut Off the Power and Water Supply: Before starting any maintenance task, ensure the unit is powered off and disconnected from the power supply. Close the water supply valve to prevent water flow into the heater.
- Locate the Filters: The location of the filters may vary depending on the brand and model of your tankless water heater. Consult the manufacturer’s manual to identify the filters and access points.
- Remove the Filters: Once located, carefully remove the filters from their housing. Pay attention to any screws or clips that may be securing them in place.
- Clean the Filters: Rinse the filters under running water to remove any loose debris and sediment. If the buildup is stubborn, you can use a soft brush or toothbrush to gently scrub away the deposits. Ensure thorough cleaning without damaging the filters.
- Reinstall the Filters: After cleaning, place the filters back into their respective housings. Make sure they are securely fitted and properly aligned.
- Restore Power and Water Supply: Once the filters are back in place, reestablish the power supply and open the water supply valve. Check for any leaks and ensure the unit is functioning correctly.
If Replacements are Necessary
If your tankless water heater has non-removable filters or the accumulated debris is too extensive to clean effectively, you may need to replace the filters. Consult the manufacturer’s manual or reach out to a professional for guidance on obtaining the correct filters and installing them properly.
Proper maintenance of your tankless water heater is essential to ensure optimal performance. Cleaning the main filters is a crucial part of this maintenance routine. While some tankless water heaters allow for filter cleaning, others require filter replacement. Consult your unit’s manual or an expert to determine the best maintenance approach based on your specific tankless water heater model. Remember, regular filter maintenance will not only improve the efficiency of your unit but also extend its overall lifespan.
