1. Fault manifestation: Does not work when power on. Cause Analysis: This situation is more likely to occur. It can be caused by poor cable contact at the power supply level. The supply voltage may change too much, causing the wires to burn or short. Solution: Pay attention to checking and troubleshooting, connect the power cord correctly, and adjust the voltage to keep it within a stable range. The coils can be replaced.
2. Fault manifestation: When the valve is open, the fluid cannot pass. Cause Analysis and Corresponding Methods: There are many situations in which this type of failure occurs. First, the fluid pressure or its operating pressure difference does not match the normal operating range. fitted; secondly, when a large amount of dirt et impurities are mixed in the valve core or moving iron core. In this case, the inside of the valve core must be cleaned. Third, the filter in front of the valve is clogged. In this case, the filter can be cleaned.
3. Fault manifestation: During startup and operation, the solenoid valve of the solar water heater leaked. Analysis of causes and corresponding methods: The first is that the pipe joints are not firmly installed and become loose. In this case, simply tighten the bolts. The first is that the outer seal of the pipe fitting is damaged. In this case, only one seal can be replaced.
4. Fault manifestation: When operating under power, the noise is extremely loud. Analysis of the causes and corresponding methods: First, the fasteners are loose, just tighten them. Second, the voltage fluctuation is too large and exceeds the allowed range. In this case, asimply adjust the voltage to the normal operating range.
No. The tripping of the solar solenoid valve is caused by a reduction in voltage across the transformer, which has been isolated from the original circuit, so the 220V solar solenoid valve will not trip due to a leak. When the solenoid valve fails, only high pressure ignition is visible and the solar water heater cannot burn. It is also the most easily broken component of the solar water heater. It is best to replace this component during maintenance.
