If your washing machine has no problem filling and agitating, but neglects to drain your problem is probably the hose or the pump. If it has no problem completing the other cycles, but will not drain your motor and belt are working fine. First off you want to do a bit of troubleshooting so that you can concretely isolate the problem. First off make sure that the drain hose does not have a kink in it. Secondly, lift the lid and check to see if the tab on the lid that hits the lid switch is in tact. Press and release the tab and if it does not click then it is probably broken and that could be the problem. Next, check to see if the water pump is broken or clogged, if you are not familiar with washers call a repairman.
Most likely it is a pump or hoses that needs fixed or replaced. This is a pretty easy fix, but if you are worried be sure to call a repairman. One more thing, before you attempt any troubleshooting or fixing turn off the machine and unplug it completely from the wall to avoid injury or shock. All you will need is a screwdriver that matches the screws and a bucket for the water.
1. Remove the drain hose from the drain and try to drain the water from the washer. To do this plug the washer back in and attempt another drain cycle. If water does not come out of the drain hose then you now know that the plumbing is in good working order.
2. Place the drain hose back into the drain and remove the washers cabinet.
3. You will now be able to see the pump and it should have two hoses attached to it.
4. Disconnect the hose coming from the basket. If water comes out you will know that nothing is clogging the basket.
5. If both of these tests come out good you now know that the problem is the pump.
6. Make sure you write down all relevant information such as the washing machine model and serial number.
7. Head to your local hardware store and buy a pump (they typically run about $15.00).
8. Remove the old pump and install the new one (make sure the washing machine is turned off and unplugged).
9. Test it. Let it run through a cycle to make sure everything is installed and working properly.
10. If it is still broken call a repairman or ask a handy friend to check it out for you.
This is fairly simple to do and doing it yourself will save you an average of $150.00. Be aware that this appliance runs on electricity so make sure you exercise precaution. Never be afraid to ask for help.
