This is a trouble code for a fill that is taking to long. Make sure that both the hot and cold water valves are turned on. Hope this helps.

Your water pump is clogged

Blocked inlet filter or kinked hose
if not then it will be your inlet valve

Usually either the lid lock mechanism, the lid lock actuator or the board is the culprit even a disconnected capacitor.

When the START button is pressed, the washer will first perform a self-test on the lid lock mechanism. You will hear a click, the basket will make a slight turn, and the lid will unlock briefly before locking again. Once the lid has locked the second time, the washer
will slowly spin the dry load to estimate the load size, and begin adding water. The washer will then move the load briefly, pause to allow water to soak in to the load, and resume adding water. This process may repeat until the correct amount of water has been
added for the load. You may also hear water flowing through the dispenser, adding detergent to the load.

NOTE: The sensing light may also come on during the Soak and Wash portions of the cycle. This is normal.

Try unplugging the cord a couple of times. See what happens then try going into diagnostic error codes, see what codes are shown. To pin point where the problem is. if you have no display to read the fault codes. Your main control board may be the issue.

Next, while in Manual diagnostics, try to get the unit to spin; if the motor hums for a split second and then shuts down with the lid lock blinking; go back into diagnostic codes and look for shifter or speed sensor errors.
This is proof that the shifter/sensor actuator assembly is the issue because the optical sensor is not reading the motor speed.

I suggest unplug the washer and check the wire connections on the switch. If a meter is available then you can check the resistance (ohms) of the lock motor.

Note: After performing the manual test and the lid lock works perfectly, or at least as it is supposed to. You can eliminate that as the problem.If the lock worked in the manual test but doesn't in an actual cycle then I suspect the control board is at fault.

A safety feature found on front load washing machine is the door switch and the door lock and strike. On most models, the door switch must be closed and the door lock must be activated before the washer will start. The switch is normally located in the door frame of the washing machine, but may also be part of the door lock assembly. Inspect the strike to make sure that it engages the door lock assembly and that the door remains closed. To check the door switch for continuity with a multi-meter, you will need to disconnect the power and remove the front panel.

The lid switch on a top load washing machine is a safety device designed to prevent the motor circuit from operating when the lOn some models, the water inlet valve circuit is controlled as well. If the lid switch fails, the washer may not start. The lid switch is normally located beneath the main top with a projection on the lid or a pin attached to the lid that will actuate the switch when the lid is closed. Verify that the switch is being activated mechanically and that any levers or actuators are not damaged or sticking. If the switch is being activated but there is no power being supplied to the motor or water valve circuits, then the switch may be defective

The start switch on some top load washers is often part of the timer and is activated by pulling out on the timer knob. Although not normally available as a separate part, the switch can be tested for continuity with a multi-meter. You will need to remove power from the appliance and then locate the correct timer contacts as noted on the wiring diagram. On some electronic controlled models, the start switch is a momentary contact type switch located on the control console. You can test this switch for continuity with a multi-meter when the push button is held in
God is good and that's why I give free advice.

remove the cold water hose from the washer look inside the parts of the washer you unscrewed it from, there is a plastic screen in there that needs to be clean out. you can pop it out with a small flat head screwdriver, clean it then pop it back in. also remove cold hose from valve on wall. there is another screen in there that needs to be cleaned. this will fix the problem
