Standing water located in your washing machine after the cycle has been completed may be an indicator that something is wrong. There could be a couple of issues that are prohibiting the water from draining properly, such as something stuck in the drain line or that the water pump is damaged. However, there is a way you can check if there is an issue with the water pump. The information below provides the steps on how to check if the water pump is blocked or damaged.
The washing machine should be unplugged and pulled away from the wall. Then you should take a pail and attempt to remove the water. Once you have removed all the water you can with the pail, take a sponge and soak up the rest.
Place a couple of blocks on the bottom of the front feet of the washing machine by tilting it backward.
There should be a couple of screws under the top of the toe-kick near the floor of the washer that hold the front panel together. Locate these screws, which would help to remove the front panel of a top loader machine, or just the part underneath the door of a front loader machine.
Once you have located the screws, remove them with a screwdriver, then take off the panel. The panel should be tilted backward so you can unhook it and remove it from the washer. This should reveal the drain pump which is attached to the bottom panel connected to the drain hose.
The clamps located on the drain hose that connect it to the pump outlet should be removed. Once you have removed the clamps, check for any blockages inside the hose. If you can't see through the hose, this is an indicator that there is a blockage. However, if you don't see anything, it may mean the water pump is faulty. Before checking it, the belt connected to the drive motor of the washer has to be disconnected.
There is a belt located under the pump flywheel of the washer that should be pulled off. The belt is black and thin and should be able to be removed just by pulling it free with your fingers. After removing the belt, the pump flywheel should slide freely. If it doesn't, then it's possible something is stuck inside. Reach a finger into the drain outlet to turn the impellers to see if it's broken. If pieces of plastic fly freely, then the impeller is possibly broken and the pump should be replaced.
If you are unsure of how to perform these steps without assistance, consider consulting an appliance service that does washer repair.
