Whirlpool Dishwasher Not Washing: How to Fix It

1. The door.

The door is the most important part of the dishwasher. It is what keeps the water and soap inside the dishwasher and it also helps to seal in the heat so that the dishes get clean.

If your dishwasher door is not working properly, then it will not be able to do its job correctly. There are a few things that you can do to fix a dishwasher door that is not working properly.

First, you need to check the seal around the door. If there is a gap in the seal, then water and soap can escape from the dishwasher. You can try to tighten the screws that hold the seal in place or you can replace the seal entirely.

Second, you need to make sure that the door is properly latched. If the door is not latched, then it will not be able to seal properly. You can try to adjust the latch or you can replace it entirely.

Third, you need to check the hinges of the dishwasher door. If the hinges are loose, then the door will not be able to seal properly. You can try to tighten the screws that hold the hinges in place or you can replace the hinges entirely.

Fourth, you need to check the springs of the dishwasher door. If the springs are worn out, then the door will not be able to seal properly. You can try to replace the springs entirely.

Fifth, you need to check the gasket of the dishwasher door. If the gasket is damaged, then the door will not be able to seal properly. You can try to replace the gasket entirely.

2. Water supply.

That is the most likely problem if your Whirlpool dishwasher is not washing. Check to make sure the water supply valves are turned on all the way.

If they are, then the problem could be with the float switch. This switch signals to the dishwasher that there is enough water to start washing. If it is defective, it will prevent the dishwasher from starting.

Why does it fail?

There are a few reasons why the float switch might fail. The most common reason is that it becomes clogged with dirt and grease. Over time, this can cause the switch to become less sensitive, until it finally fails altogether.

If you think your float switch might be the problem, you can try cleaning it. First, remove the dishwasher from its power source. Then, locate the float switch and unscrew it from its housing.

Use a toothpick or other sharp object to clean out any dirt or debris that might be clogging the switch. Once you’ve cleaned it, screw the switch back into place and turn on the power. Try running a cycle to see if the dishwasher works.

How to prevent it?

You can prevent the float switch from failing by regularly cleaning your dishwasher. This will help to remove any dirt and grease that could clog the switch.

You should also make sure to regularly check the float switch for any signs of wear or damage. If you notice anything, be sure to replace the switch right away.

3. Power supply.

Check the circuit breaker or fuse, and reset if necessary. If your dishwasher is hardwired to the electrical system, be sure to shut off the power at the circuit breaker before continuing.

Look for a loose or damaged wire behind the control panel. If you find one, repair or replace it as needed. Check for loose connections at the main terminal block. If any are loose, tighten them with a wrench.

4. Water Inlet Valve.

If your dishwasher is not washing, one possible reason is that the water inlet valve is not working. This valve controls the flow of water into the dishwasher, and if it is not functioning properly, the dishwasher will not be able to get enough water to clean the dishes.

Why does it fail?

There are a few reasons why the water inlet valve might fail. One possibility is that something is blocking the valve, such as a piece of dirt or debris. Another possibility is that the valve itself is damaged and needs to be replaced.

How to fix it?

If you think that the water inlet valve is the problem, you will need to take a look at it and see if there is anything blocking it. If there is, you can try to remove the obstruction and see if that fixes the problem. If the valve itself is damaged, you will need to replace it with a new one.

5. Water Pump Belt.

The water pump belt is located under the dishwasher. It is a black rubber belt that goes around the dishwasher’s pump.

If your dishwasher is not washing, one possible reason is that the water pump belt has broken. To check this, open up your dishwasher and look for the water pump (it will be a circular device with a black rubber belt going around it).

If the belt is broken, you will need to replace it. Fortunately, this is a relatively easy repair that you can do yourself.

To replace the water pump belt, first disconnect your dishwasher from power. Then, remove the dishwasher’s access panel (this will be located under the dishwasher).

Once you have the access panel off, locate the water pump (it will be a circular device with a black rubber belt going around it). Next, remove the old belt and replace it with a new one. Finally, reattach the access panel and reconnect your dishwasher to power.

How to prevent it?

Inspect the water pump belt every few months to make sure it is not worn out or damaged. If you notice any damage, replace the belt immediately.
