Whirlpool washing machine pump repair

Whirlpool washing machine pump repair

The pump of the automatic machine constantly experiences heavy loads, pumping wastewater from the tank into the sewer. In addition, the part is subject to heavy wear, so over time, it may fail. Can a Whirlpool washing machine pump be repaired? How to check and repair an element? Let's take a look at the nuances.

Does the pump need repair?

Only sometimes, the cause of a non-functioning drain is a broken pump. However, there may be other problems in the drainage system. Therefore, before repairing or changing the pump, check all the sore spots of the Whirlpool washers in sequence.

Clean the trash filter. Often the machine cannot drain the water from the tank precisely because of the blockage of the filter element. Behind a decorative panel or special hatch, the trash bin is in the Whirlpool CMA's lower corner. Unscrew the spiral, and clean it and the resulting hole from debris and dirt. Often inside, you can find coins, buttons and even socks. After removing foreign objects, return the plastic part and start the test cycle.

Examine the drain hose. Perhaps the corrugation is bent, or a blockage has formed inside. Carefully feel the tube, disconnect it from the washer body and the connection point to the sewer, and then rinse under warm water. Then run a test drain. If the machine is further naughty, it must continue the diagnostics.


Check the impeller stroke. To do this, unscrew the garbage filter and look into the hole formed. The impeller will be visible there. First, check if there is any foreign object stuck between the blades. Also, remove wound threads and hair from them. Next, scroll the part with your fingers - it should rotate freely. If the movement is easy, most likely, the problem is in the pump itself.

You can understand if the drainage pump is in order if you listen to its work. Therefore, run the wash and analyze the sounds made by the Whirlpool machine. If the washing machine starts to buzz intensely at the draining stage and the water does not go into the sewer, we can discuss a pump malfunction. Complete silence will also indicate a breakdown since a measured, implicit noise must still be present.

A multimeter is required to diagnose the pump. With it, you can test the integrity of the stator winding of the part. In addition, the contacts and sensors of the pump are visually checked - they should not have any signs of damage.


Also, the reason for the missing drain may be in the CMA control board. However, the electronic module fails extremely rarely. Therefore, most likely, the drain pump of the automatic machine will have to be replaced. Let's figure out how to repair the washer.

Consumables for repairing the pump

No special tools are required when repairing othe washing machine pump. It will be enough to arm with a conventional Phillips screwdriver. Although a penknife may also come in handy, it is better to have it on hand.

To diagnose the pump, you need a multimeter. The device can be bought at home appliance stores or ordered online. The tester is inexpensive. There are models for 1000-4000 rupees.

The number of components for the repair of SMA Whirlpool directly depends on the extent of the breakdown. However, in the worst case, you will have to purchase the following:

  • Pump,
  • Impeller,
  • Pump sensor,
  • Sealant,
  • Contacts,
  • Axis,
  • Gasket,
  • Pulley.

As already mentioned, this is a set of spare parts for the worst case of a pump failure. In most cases, simply purchasing a new pump is sufficient. So how to choose replacement parts?

You can dismantle a broken pump and go to the store with it. The seller, focusing on marking the part, will select a similar one. When ordering a pump online, check all the information to buy the components suitable for your Whirlpool model.

Getting to the pump

The pump is located on all Whirlpool models in one place - at the bottom of the case, regardless of whether it will be a direct drive model or a belt drive. So you don't have to disassemble the washer to get to the pump. Enough:

  • De-energize the automatic machine,
  • Close the shut-off valve,
  • Disconnect the device from the water supply and sewerage;
  • Drain the remaining water from the system by unscrewing the garbage filter,
  • Cover the floor with a blanket,
  • Lay the washer on its left side, on a soft substrate,
  • Remove the pan (if any).

Remember that water will pour out of the hole when unscrewing the garbage filter. Therefore, cover the floor in this place with rags, or substitute a low container under the SMA.

It remains only to look inside the washer and find the pump. Now you can diagnose the element and, if necessary, replace it. If you have doubts that you will cope with the repair, it is better to seek help from the service center specialists.

First of all, the part is checked with a multimeter. The tester's probes are leaning against the contacts of the pump, after which the readings on the device screen are evaluated. Normally, the output resistance should be 150-250 ohms.

We are looking for a problem in the disassembly process

The key step is disassembling the pump. Only during this procedure will it be possible to understand whether the impeller is scrolling and how securely the latches hold it. An internal check is necessary if the movement of the blades is difficult but there are no visible obstructions - debris or foreign objects.

Whirlpool machines can have standard pumps, considered collapsible or non-collapsible elements. In the first case, you need to act as follows:

unhook the pump from the snail by removing the fixing bolts;

  • Push on the part from the side where the drain valve is located, then pull the body towards you,
  • Drain the accumulated water from the body,
  • Pry out the fixing latches on both sides of the pump,
  • Remove the pump from the coil.

Can split even non-separable pumps in half. In this case, you need to act more carefully. The algorithm will be as follows:

  • Put on protective gloves,
  • Unhook the pump housing from the snail and coil,
  • Take a building hair dryer, run the lowest temperature blowing program,
  • Warm up the tail of the pump (this is a long tip located at the back) for several minutes,
  • Pick up the crosspiece with a screwdriver, and remove it from the case,
  • Also pull out the magnet, because of which the structure is considered non-separable,
  • Clean the magnet and the seat from debris, plaque and dirt,
  • Remove the magnet from the pump shaft.

Sometimes, to fix the pump, it is enough to clean its insides. Therefore, you can remove debris, lubricate the bearings on the magnet, and assemble the part back. However, you must change the pump if such actions do not work.

Before installing a new pump, be sure to clean all elements of the drain system. We are talking about a snail, summed-up pipes, and a seat. The part is fastened with bolts removed during dismantling.

When installing the new pump, be sure to test the washing machine. Run an idle cycle with no laundry in the drum. A short Rinse + Drain mode will suffice. Can complete the repair if the water flows freely into the sewer.
