LG wm2688hwma throwing FE error. Replaced both water inlet valves and water level pressure switch. Very easy to get to the valves and pressure switch. Needed a bunch of towels to deal with the water coming out from the various inlet valve hoses. Needed a philips screwdriver for the washer lid, inlet valves and pressure switch. Needed pliers for removing the clamps on the inlet valve hoses. Needed an adjustable wrench for removing the water line hoses. Fairly straightforward and easy repair. After replacing these parts the washer is working again.
