      If your NorthStar Water Heater isn't running and has no power, first, ensure the machine is properly plugged in. If it is, check the GFCI and make sure the machine is dry, then press the RESET button on the GFCI.

      If you're experiencing poor or no detergent supply with your NorthStar Water Heater, start by adjusting the soap control knob. If that doesn't work, refill the detergent container, ensuring the chemical strainer is fully submerged. Also, try using less high-pressure hose or moving the machine closer to your work. Finally, clean the chemical strainer and injector, always starting with a clean detergent container and running clean water through the injector after each use.
