If the direct solenoid valve joint is loose or offline, the solenoid valve shall not be energized, the joint can be tightened.

If the solenoid coil is burned out, remove the cable from the solenoid valve and measure it using a multimeter. If the circuit is disconnected, the solenoid coil will burn out. The reason is that the coil is damp, resulting in poor insulation and magnetic leakage, resulting in excessive current in the coil and burn, need to prevent rain water into the solenoid valve. In addition, the reaction force on the spring is too large, the number of turns of the coil is too small, and the insufficient suction will also make the coil burn out. For emergency treatment, the manual button on the relief solenoid coil can be moved from the "0" position to the "1" position during normal operation to open the valve.

If solar energy water heater is in reenergize condition below solenoid valve still did not start, the likelihood is contact undesirable, whether checking power line is received, adjust voltage. If fluid does not pass after opening the valve, pressure adjustment or cleaning of the spool/filter is required. If the electromagnetic valve of solar energy water heater starts from time to time outside leakage, should fasten the bolt of pipeline joint place. If the water pressure is low, it is recommended to choose no pressure valve.

In the solar water heater, electromagnetic valve is a very important equipment, in the solar water heater, electromagnetic valve plays two very important roles. One method is a switch or valve that instead of filling water manually, the other is for the solar water heater to automatically open the valve to release water when it is automatically empty.
