Water Inlet Valve Assembly
The inlet valve contains electromagnetic solenoids that actuate rubber diaphragms to allow water flow; these frequently fail due to internal coil burnout or mineral deposits seizing the plunger. If the valve fails to open mechanically, the machine will not detect water entry, triggering the 4C timeout. This assembly is the primary electromechanical interface responsible for water delivery.

Water Inlet Mesh Filters
These fine mesh screens sit inside the valve inlets to prevent sediment from entering the tub; they are highly susceptible to clogging from hard water scale or pipe debris. A significant reduction in flow rate (GPM) through a clogged filter will prevent the water level from rising fast enough to satisfy the control board's timing logic, resulting in a 4C error.

Water Level Pressure Sensor
The pressure sensor converts the pneumatic pressure in the air dome tube into a frequency signal for the PCB. If the internal diaphragm of this sensor is ruptured or the transducer is faulty, the machine will fail to register the 'water present' state even if the tank is filling, leading to an intentional shutdown and error code to prevent overflow.
