The high-efficiency top load washer is a relatively new design in washing machines. This type of washing machine has a large plastic tub on the upper portion.
The clothes are washed by paddles in this container. Because there’s no agitator, large items like blankets or sleeping bags can be washed without twisting or tangling.
High-efficiency washers use less water and electricity than the older, top load washing machines.

How to Troubleshoot a High-Efficiency Top Load Washer
The primary complaint with this type of appliance is that it stops working in mid-cycle. Before calling for service, try troubleshooting your machine yourself.
Here are some common causes of failure along with possible solutions for fixing or preventing them.
- The water pump typically fails when debris gets inside it. If you have a sink or outside hose nearby, try using the hose to pump out any dirt, lint, or hair caught in the filter screen.
- This pump is located at the bottom of your washing machine’s tub and is attached to the drain hose.
- If there are no blockages in the pump, it may have a bad bearing. The washer will not fill because the lid switch prevents it from operating when the lid is open.
- You can check to see if it’s an electrical problem by following these steps:
- Unplug the machine and remove its front panel (unplugging stops all cycles)
- Use your multimeter and probe for voltage at the pump. You should see 120 volts coming from the machine’s power cord, but not when plugged into a socket
- See if you don’t have any voltage now, it may be an electrical problem with the switch or wiring in your machine
- If you do have voltage at this point, then the lid switch is faulty and needs to be replaced
- If you don’t, the pump is probably bad and needs to be repaired or replaced
Your washer’s control panel may also fail for a number of reasons. Some common causes of failure include:
- The door switch fails when debris gets in it. You can try to clean out any dirt or lint that’s clogging the switch and then manually open and close the lid to see if the washer starts working again
- The lid switch may be faulty and needs to be replaced. If you remove it, you should be able to move it back and forth. If not, replace it
- The keypad assembly is often the part that fails on a high-efficiency washer. If this is the case, you will need to replace it
The pump impeller can fail due to debris. Unplug the machine and take the front panel off. Then, remove the drive belt from around the pump pulley or motor flywheel by releasing tension on the belt from the idler pulley using a screwdriver.
Once done, use your fingers to turn the impeller and see if it’s loose or stiff. If it feels very tight, you can try spraying a penetrating oil onto the part and waiting a few hours for it to work. Otherwise, replace the pump.
Faulty Door Switch
The door switch is the most expensive mechanical failure in a high-efficiency washing machine. You can try by manually opening and closing the lid, but it’s typically a better idea to replace the entire assembly
Door lock problem
If your washing machine doesn’t start from mid-cycle, make sure that the washer’s door is securely closed. If it still doesn’t start, remove the control panel and make sure that its safety switch is working right. This switch prevents electrical problems if a small child tries to open or close the lid while it’s running
If your washing machine doesn’t drain all of the water out, try these tips:
Check your home’s drain line and ensure that it’s clear. A root-clogged drain line is the most common cause of a failed pump
You can also try removing your washer’s plug and pushing down on its agitator to see if any water comes out, which will help you figure out if the pump or your home’s main drainage system is at fault
Spin bearing failure
When your high-efficiency washing machine won’t spin, it can often be fixed by these simple steps:
- Check all of the appliance’s lid switches. This part will need to be replaced if any are broken or defective
- Clean out any dirt or lint that may have clogged the drain pump filter screen
- Verify that the belt isn’t broken and is properly seated on the pulley
- ·Ensure that any idler pulleys or couplings are in working order. If one of these parts fails, you will need to disassemble and replace it. Once done, verify that all belts and pulleys rotate freely before reassembling the washing machine
Spin bearing failure
If your washing machine doesn’t spin, try these steps:
- Remove the belts from around the pump pulley or motor flywheel. You can use a screwdriver to release the tension on the belt from the idler pulley
- Unplug the appliance and remove its front panel – this will stop operation so you can work on the machine safely.
- Remove the drive belt from around the pump pulley or motor flywheel by releasing tension on the belt from the idler pulley using a screwdriver. Use your fingers to turn the impeller and see if it’s loose or stiff. If it feels very tight, you can try spraying a penetrating oil onto the part and waiting a few hours for it to work. Otherwise, replace the impeller
- Remove the door switch by unplugging your washer and turning off its circuit breaker, which you will find in the main service panel. Then, remove the screws holding on the front panel before lifting it up
- You can also try removing your washer’s plug and pushing down on its agitator to see if any water comes out, which will help you figure out if the pump or your home’s main drainage system is at fault.
- If the washing machine doesn’t have a belt-driven pump, remove the drain hose from around the impeller located under the bottom panel of your washer. Also, take off any screws that are holding it in place before removing the pump
- Finally, inspect these parts closely for damage. If one of them looks worn or damaged in any way, you will need to replace it. Once done, verify that all belts and pulleys rotate freely before reassembling the washing machine
Replace Top Lid Lock
If none of this helps when repairing a high-efficiency washer, then it can be smart to replace the top lid lock assembly.
The faulty top lid lock assembly will need to be replaced. Once complete, verify that all belts and pulleys rotate freely before reassembling the washing machine.
