Dishwashers have many moving parts. If your dishwasher stops filling with water, there are many little things that could potentially be going wrong to cause the problem. In this tutorial, we’ll walk you through some of the basic problems your dishwasher could be experiencing.
Before you start replacing parts, it’s a good idea to confirm that your dishwasher has power and water. You can check that the water is turned at the local valve under your sink. Check that the valve is open. Remember: righty-tighty, lefty-loosy.
Next, use a multi-meter to check that the outlet the dishwasher is plugged into has power. If you don’t have a multi-meter, you might be able to borrow one from a neighbor. If you’ve never used a multi-meter before, check out this video:
If your dishwasher has power and water, check the water inlet valve for functionality. The water inlet valve is located under your dishwasher. If you’re not sure how to test the water inlet valve, you can check out this tutorial online.
If your water inlet valve needs replacement, you can buy a new one online. Remember to search for a valve that works with your dishwasher’s specific make and model. Once you’ve gotten the new inlet valve, this is how you’ll replace it:
This process has been documented in this helpful video:
Although the fill valve is one of the most likely reasons your dishwasher may be broken, there are other problems your dishwasher could be experiencing. Your next course of action will be to check the float assembly and float switch.
The float is the moving part inside your dishwasher that senses the level of the water inside the unit. The float triggers a switch (creatively named the “float switch”) to turn off the water. If a piece of debris becomes caught in the float assembly or in the switch, the water could remain permanently off. A float that is stuck in the off position will be located up high on the float assembly. The switch will be located near the top of the float assembly. Check both for debris.
That’s it. We hope that following these instructions will help you fix your dishwasher. Do you have other suggestions? Leave your comments in the box below! We’d love to hear what’s worked for you!
