This may be due to the high water level warning set in the meter. It doesn't matter if you use manual filling, just stop filling the water. If you're using autofill, don't worry. this is not good, you can readjust the probe position and configure the counter!
Recommended "Dr. Sun" solar power (combination of solar power + electric water heater, lower electricity bills), three barrel model (no need for water level detection probe and solenoid valve), rapid heating and hot water use in rainy days, and the after-sales rate is also greatly reduced, saving time and energy. This model only takes 20-30 minutes to heat without sunlight, while a single warehouse takes 2-3 hours! p>
