The meaning of the PE fault in LG washing machine by MyApplianceRepairHouston.COM

What does the PE error in LG washer mean? It reports about the water level switch (pressure switch) fault. The system issues the error code after a 25-minute timeout. During this time water should reach the minimum level. Or there is an excessively fast filling of the device – in just 4 minutes.

How to fix the breakdown by MyApplianceRepairHouston.COM

In 90% of cases, the cause of the PE error is the failure of the water level switch. You need to check it and replace if necessary.

What to do to fix the problem forever:

  1. Turn off the power supply to the LG washing machine, shut off the water.
  2. Unscrew bolts of the top panel of the appliance, move it aside.
  3. At the very top, you will see a pressostat. It controls the amount of water in the tank.
  4. Inspect the pressure tube for damage. Check the connection strength.
  5. Using a multimeter, you can check the wiring that connects the level switch to the controller.
  6. If everything is in order, change the pressure switch to the serviceable device.

Less often, the fault is caused by a control module. In this case, the error lights up on a display after the inclusion or when selecting the program. You can remove the block by removing the front panel of the machine where it is located.

If you see that the control board has burnt, replace it. If notice contacts breaking, solder them. The main thing is to remember their location correctly.
