As for the situation "the solar water heater meter shows it is full of water, but the water cannot be drained", there are generally several reasons: 1. The sensor is broken. For water quality reasons, scale will affect the sensor. Some sensors will be corroded by scale and water, causing water to enter the probe point, causing the sensor to malfunction and still indicating that it is full of water.
2. Pipes are frozen and blocked. After filling with water, due to low temperature at night, insufficient insulation performance of the water tank, insufficient pipe insulation and lack of anti-freeze tape, the sewer pipes. are frozen and blocked.
The solution is as follows
1. Go to the roof to check the water level in the water tank (the water temperature in the water tank can be very high, be careful of burns)
2. If you buy one thisAnti-freeze frame is installed. It can be used after plugging it in for more than ten minutes. If it still cannot be used, check whether the insulation. is disconnected at the water outlet of the water tank.
3. Call a repairer, it's the simplest and most effective.
