The work principle
The inlet valve is electromagnetic valve that decide whether water enter or not. Valves are
normally closed. Each time the appliance requires water, the controller will convey an
electric signal to the coils to open the valves.
The inlet valve consist of electric coil, valve body, valve pole, filter etc.
In a word, the electromagnetic valve can act to allow water enter into machine, when it
receive the order given by controller.
The defeat point
1. The valve coil is broken, so the valve can't open. It will cause the E1 error.
2. The filter is jammed, so water can't enter. It will cause the E1 error.
3. The connector is loose, so the valve can't open. It will cause the E1 error.
4. The valve pole is rusted or locked by dreg, so the valve can't open or close. It will cause
the E1 or E4 error.
