How to check the pump on an LG washing machine?

How to check the pump on an LG washing machineThe drain filter of any washing machine must be periodically cleaned of accumulated debris. But, unfortunately, such a measure cannot completely protect against malfunctions in the washer drain system. Only large debris and foreign objects that fall into the drum along with things settle in the trash filter. Hair, fibers, small pieces of paper, particles of plaque, bypassing the filter element, fall into the pump, and interfere with its normal functioning. We will figure out how to check the drain pump on an LG machine, where to start acting.

Pump diagnostics

After you get to the drain pump, you need to stock up on a screwdriver, unscrew the snail securing bolts from the power supply unit. Then you should disconnect the engine with the impeller. Check the cochlea for clogging; if there is debris in it, clean the part.

Inspect the gaskets; they should be clearly shaped and not worn.

You can check the operation of the washing machine pump without removing the part from the electric motor. In this case, a multimeter is useful. Tester probes are applied to the pump contacts. If the display does not show readings, therefore, the pump must be replaced.disassembling the pump of the LG washing machine

In some cases, when rubber gaskets are deformed, liquid enters the pump. Water flushes grease off the rotor, causing the part to wear out faster. The pump in this situation should be treated with a lubricant. When choosing a composition, special attention should be paid to it:

  • moisture resistance;
  • heat resistance;
  • consistency (it should be thick).

Silicone grease meets all the requirements and is perfect for processing a drain pump. After the procedure, the pump must be reinstalled.

Mechanical diagnostics will consist in checking the stroke of the impeller, as well as the wear of the bushings, for this it is necessary to remove the cochlea. The impeller should be turned manually. During normal operation, the rotation of the part is intermittent. The jerky movement is determined by the magnetic rotor. After you need to sway the impeller left to right. If significant play is detected, you will have to change the pump.

If during the described actions no malfunctions were detected, you need to proceed to the final diagnosis. It will be to connect the motor directly to the mains. To do this, prepare a wire with a plug and two terminals. When plugged in, the pump should function without making any extraneous sounds.

Explore the snail

If you heard an uncharacteristic rumble in the area where the drain pump is located (and this is the lower right side of the casing), then it is likely that a small object has fallen into the cochlea of ​​the pump or a significant blockage has occurred. Checking the pump of the AlGi machine will be as follows:

  • get access to the trash filter (it is located behind a small door located at the bottom of the front wall of the housing);
  • gently unscrew the cover;

When working with the drain filter, water will leak from the system, so the floor under the machine must first be covered with a rag.

  • Enlighten the opened cavity of the cochlea with a lantern and inspect it for foreign objects and blockages. In a normal situation, only the impeller of the pump should be visible inside.check the snail

After removing the garbage and cleaning the cavity of the cochlea, you can screw the lid back to its original place, start the machine in test mode. Another common cause of loud noise from the pump's location is the clogging of the inlet. The hose must be cleaned with a special rod and rinsed under running water.

Signs indicating a broken pump

Before you start the diagnosis of the drain pump, you need to make sure that the problem is real in it.Listen to the work of your "home assistant", focus on external signs of trouble. The pump malfunction is indicated by:

  • the corresponding error code shown on the display;
  • problems with draining the water from the tank during the washing process and upon its completion;
  • failures to enable / disable the pump.

We talked about how to make a diagnosis. Remember that irregular water leaving the tank is a sure sign of damage to the pump. Following the instructions, the machine can be repaired with your own hands, without the help of a master.
