While maintaining a tankless water heater is straightforward, the video “Tankless Water-Heater Maintenance” makes the process easier. Of course, before starting the process, review the owner’s manual to locate the parts and identify any special requirements. Read on to learn more!
There are three steps, and the first step is to clean the air filter. To do that, ensure the unit is unplugged, remove the air filter, and clean it with a brush and a water-dish soap solution. Once clean, rinse it, dry it with a lint-free cloth, and reinsert it.
The second step is to clean the water filter located near the cold-water inlet. Close the inlet valve so it is perpendicular to the line, remove the filter, tap it, and run water through it. You may need a cotton swab to remove the remaining debris before reinserting the filter.
The third step removes the hard water deposits from the system. This step is more involved, so you should follow the process outlined in your manual. Still, generally, you connect a circulation pump to the service valve and circulate several gallons of food-grade white vinegar for an hour.
Once that is complete, the fourth step is to flush the system with cold water for five minutes. Follow these steps to keep your unit running well. That’ll help avoid tankless water heater repair bills.
