Troubleshooting; The inlet valve of the machine is mainly composed of an electromagnetic coil, a valve core, and a corrugated membrane. Its working principle is as follows: when the coil is powered, the central hole valve core is lifted, and the water from the inlet flows down through the center hole of the corrugated membrane, causing the corrugated membrane to rise and allow water in. When the water reaches a certain level, the water level detection switch automatically cuts off the power, the electromagnetic coil loses magnetism, the valve core drops, and the center hole is blocked. Water then flows into the guide device through a small hole. Due to balanced pressure, the corrugated membrane descends, stopping the water supply. Haier washing machine repair. Upon connecting the power, the voltage across the coil terminals of the inlet valve was measured at 220V AC, which is normal. Then, using the Rx1kΩ setting to test the electromagnetic coil resistance, it was found that the resistance of the inlet valve coil was infinitely large. Normally, this resistance value should be around 4.5KΩ. Based on this, it can be concluded that there is an open circuit in the inlet valve coil. After replacing the inlet valve with the same model, the machine was tested and the washing machine functioned normally, resolving the fault.

Fault analysis: Based on the fault phenomenon, it is possible that there is a problem with the inlet valve.
