The impeller of the washing machine drain pump flies off

The impeller of the washing machine drain pump flies off

If, during the process of diagnosing your automatic washing machine, you discovered that the plastic impeller of the drain pump has begun to fly off, you can repair the part yourself. This can be done in two ways: by reanimating the old pump impeller, placing it again in its seat, or by completely replacing the pump.

Restoring the impeller itself will be ineffective, since its flight occurs due to wear not of the plastic part itself, but of the seat. A more reliable option is to replace the pump. We will analyse both methods of troubleshooting and explain how to do it yourself.

Changing the pump

If the impeller of the washing machine drain pump has come off, it would be best to install a new pump. We will try to explain in detail how to dismantle the old part and mount a new pump with your own hands. The algorithm of actions is quite simple and can be applied to washing machines of LG, Whirlpool, Ariston, Candy, Samsung, Beko, Ardo models.

  • Carefully lay the automatic machine on its side; it is better to place a soft blanket under it to avoid damaging the body wall.
  • If the washer has a bottom, unscrew the bolts holding it in place and move the tray to the side.
  • Remove the back wall of the washing machine.
  • Use your hands to inspect the drain hose for foreign objects and blockages.
  • Loosen the ring securing the pipe and disconnect the hose from the drain pump.
  • Unscrew the screws holding the pump, disconnect the power wires connected to it, and remove the element from the housing.
  • Install a new pump; to do this, secure the part in the housing, connect the wiring and drainpipe.

If you are the owner of Bosh, AEG or Siemens washing machines, the algorithm of actions will be slightly different.

  • Unscrew the bolts holding the top cover of the unit and remove it.
  • Remove the detergent tray from the housing.
  • Unscrew the bolts securing the control panel of the washing machine, then, using a flat-head screwdriver, unfasten the special plastic latches around its perimeter.
  • Carefully place the control panel on the top of the case without disconnecting the power wires.
  • Remove the false panel located at the bottom of the washing machine, under the hatch door.
  • Loosen the clamp holding the hatch cuff, remove it and tuck the rubber seal inside the drum.
  • Disconnect the wires leading to the sunroof locking device.
  • Unscrew the screws holding the front wall of the case and move the panel to the side.
  • Find the drain pump and dismantle it.
  • Install a properly functioning element by connecting the drain hose and power wires to it.
  • Reassemble the machine in reverse order.

This repair method will be the most correct. After completely replacing the drainage pump, the part will last for several years, while if you replace an impeller that has fallen off, you risk encountering the same problem after several wash cycles.

Installing the impeller in place

If you cannot quickly purchase a new drain pump, you can use a simpler, but at the same time not very reliable option - try to put the impeller in place using waterproof glue or sealant. If you fasten a plastic part in this way, you can correct the situation, but just for a few wash cycles. It will not be possible to operate the machine for a long time since the impeller will soon fall off and the waste liquid drainage system will fail again.

So, if the impeller is broken, and there is no time to fully replace the pump, you can do the following:

  • Gain access to the impeller mounting point,
  • Thoroughly dry the shaft on which the plastic part stands,
  • Degrease the shaft with a special product,
  • Apply anaerobic sealant or moisture-resistant glue to the seat,
  • Plant the pump impeller on the shaft.

Try to replace the faulty drain pump with a new one as soon as possible. This way you can forget about the problem of draining water for many years.

If the impeller turns?

In such a situation, the automatic washing machine begins to drain the waste liquid from the tank, then the pressure becomes very small, and as a result, the water either takes a very long time to drain or does not drain completely and remains in the tank. At first glance, the drain pump may seem to be fully operational, the pump impeller sits tightly in place, so what’s the problem?

Most likely the impeller is turning. During normal operation, if you rotate it with your fingers, the impeller should rotate in jerks, this indicates that the pump magnet is overcoming resistance. When the impeller rotates freely and spins on the axis without stopping, it means that the device is not working properly. Such scrolling can be caused by foreign objects that periodically enter the drain system or by a banal factory defect.

There is only one solution to the problem - completely replacing the drain pump of the washing machine. You can purchase it at specialized retail outlets or online stores using the machine model number.
