One of the most common problems with an instant water heater control board is its failure to heat water. This issue can stem from several factors, including a faulty thermostat, a malfunctioning heating element, or power supply interruptions.
Fix: Begin troubleshooting by checking the power supply to ensure the heater is receiving the correct voltage. Next, inspect the thermostat settings and heating elements. If these components are working correctly, the control board might need to be replaced.
