A washing machine pump is typically used to pump the water out of the washer tub in a domestic washing machine. It contains an impeller that rotates in the intended direction of the water flow. They are typically located below the level of the washer tub. Washer pumps get their mechanical rotational motion from the washer motor. This motion is transferred to the pump either by a belt or by a direct drive method. In the case of a belt, wearing or stretching can often cause slippage on the pulley of the motor or pump. This will cause the washer to not drain property or at all. In the case of a direct drive system, a motor coupler is used to turn the pump.
How to buy Washer Pumps
There are numerous websites out there that sell Washer Pumps. Pay close attention to the price and shipping charges. Many websites will charge a low price for Washer Pumps, but a high price for shipping. Also, try to buy Washer Pumps from the original equipment manufacturer (OEM), if possible. This will help ensure that they are within the proper specifications for your appliance.
Washer Pump Troubleshooting and Repair Tips
How do you know if your washing machine pump is bad? A tyupical symptom is that your washer will not drain. In the case of a bad pump, it typically could be locked up (because perhaps a sock or some other item has lodged itself in the pump) or the internal impeller has broken free from the shaft. In either case, the pump will no longer pump water out of the washer. If the water won't pump out, then the washer will not effectively spin either.
To access the pump, first unplug the washer. The tub should then be drained. This can be done in several ways. Some common ways are to siphon it out or to simply dip it out with a small bucket. Once drained, the washer must be disassembled. The pump hoses should be removed and the pump checked for internal blockages. Remove the coupler or belt from the pump and attempt to turn the pump shaft. If it cannot be turned, it may be locked up.
If the washing machine pump is deemed bad, replace it with a correct model and reassemble the mechanism and washer. Plug the washer back in and test by adding a small amount of water and then placing the washer in the spin cycle. The washer should now drain. Be sure to run the washer through all of the cycles to make sure it works properly.
