Role of the Dishwasher Water Inlet Valve
An important part of a dishwasher is the water inlet valve which controls how much water comes into the dishwasher to ensure that the right amount of water is used for the washing cycle. At system signals from the control system, the water inlet valve opens when the dishwasher is ready to begin a wash cycle, to allow water into the appliance.
Many problems can be caused by a faulty dishwasher water inlet valve. A dishwasher that doesn’t fill with enough water can be caused by a valve that doesn’t open or only opens partially. The dishwasher water inlet valve plays an important role in the proper operation of the appliance and also in ensuring that water is used efficiently during the cleaning process.
Common Signs of a Faulty Dishwasher Water Inlet Valve
It’s important to recognize the symptoms of a faulty dishwasher water inlet valve so that you may take the necessary steps for repairs and have your appliance back to working in the best condition.
Diagnosing a Faulty Dishwasher Water Inlet Valve
When troubleshooting issues such as a dishwasher not draining or dishwasher water not filling, it's essential to consider the water inlet valve as a potential source of problems. Here's how you can diagnose a faulty water inlet valve:
Differentiating between Valve and Drain Hose Issues
- The first thing is to check whether the problem is with the water inlet valve or the drain hose of the dishwasher is blocked. Check the twist and turn off the drain hose to look out for any twist and turn that will obstruct the free flow of water and cause trouble in its draining.
Inspecting the Valve for Visible Damage
- Check the water inlet valve for wear and tear, rust, or build-up of deposits on the valve physically. These problems may point to a problem with the valve and it may have to be repaired.
Testing with a Multimeter for Electrical Continuity
- The continuity of electricity to proceed with the diagnosis of the water inlet valve can be checked with a multimeter. This means looking at what electrical signals are going to the valve and whether or not the valve is responding appropriately to them.
By following these diagnostic steps, you can effectively assess the condition of the water inlet valve and determine whether it is responsible for the drainage or water-filling issues in your dishwasher.
Dishwasher Water Inlet Valve Replacement
- Disconnect power and water supply: One of the most important things to do before attempting to start work on a dishwasher is to prioritize safety. Start by switching off the power at the circuit breaker and the water supply to the dishwasher so you don’t get electrocuted or have water leakage when replacing the dishwasher.
- Locate the water inlet valve: To remove the water inlet valve on the dishwasher, remove the access panels you need to get to it. The location of these panels can be on the front or sides, depending on the model. Lastly, carefully remove the panels to see where the water inlet valve sits.
- Remove the faulty water inlet valve: Pull out any retaining clips or screws which is securing the water inlet valve in place and disconnect it. Next, disconnect the water inlet and outlet lines tapped to the valve, knowing that any remaining water will be caught and contained.
- Install the new water inlet valve: Reconnect the water lines with the new water inlet valve making sure you get a good, leak-free connection. Let the electrical connectors reconnect to their terminals snugly and lock the valve down using any clipped or screwed-in clips or screws that were removed.
- Reconnect and test: Install a new water inlet valve and reattach any access panels that would have been removed earlier. Turn the water supply on and turn the power back on at the circuit breaker. Run a test run of the dishwasher to verify that the new water inlet valve is working correctly and there is no leakage.
