EBF63534902 Genuine Pressure Switch for LG Washing Machines, LG Water Level Sensor Switch Replacement

LG part EBF63534902 is a genuine pressure switch for LG washing machines, the sensor that tells the control board how much water is in the tub. It connects to the tub by a thin air hose, and the air pressure in that hose rises as the water level climbs. No model list is on file for this switch, so match the number on the old part or send us the model number from your washer's label.

Overfilling, underfilling and fill errors on an LG washer

As water enters the tub, air trapped in the pressure hose is squeezed and the switch reads that change as a water level. The control board uses the reading to stop filling, start the wash and confirm the tub has emptied. A faulty switch can make the washer overfill, stop filling too early, keep filling and draining in a loop, or show a fill or drain error even though the valves and pump are fine. Check the small air hose for splits, kinks or blockages first, as these give the same symptoms.

Fitting the pressure switch

Disconnect the power plug and close both taps. Remove the top or rear panel to reach the switch, usually high on the cabinet. Ease the air hose off the old switch, unplug the wiring and unscrew it. Before fitting the new one, blow through the hose to make sure it's clear and check it isn't kinked. Run a short program to confirm it fills to the right level.

Questions about this part

Can a blocked hose cause the same problems?

Yes. If the small air hose to the pressure switch is split, kinked or blocked with residue, the switch can't read the water level properly. Always check and clear the hose before replacing the switch.
