Troubleshoot Why A Dishwasher Will Not Fill With These 4 – Steps

Step-1. Incoming Power

You will need to find your breaker box and locate the breaker that is dedicated for your dishwasher.  Flip the breaker off and on even if the breaker looks like it is already in the on position.  Now go and try to start your dishwasher again.

Step-2. Water Supply

Make sure that the incoming water supply to the dishwasher is turned on.

Step-3. Water Inlet Valve

Troubleshooting the water inlet valve solenoid for continuity, test the solenoid using a multimeter, If the solenoid does not have continuity, this is more than likely the reason why your dishwasher won’t fill with water.  The water inlet valve is bad and it will need to be replaced to fix the problem.

Step-4. Float Switch

Troubleshooting the float switch assembly, located inside of the dishwasher, on the bottom part of the tub.  It is used to control the desired amount of water that enters the dishwasher, as the water enters the dishwasher the float rises with the water.  When the correct amount of water has entered the machine, the switch is then activated, shutting the flow of water off.  If the float gets stuck, it will not rise, the switch won’t be activated, causing the dishwasher to over flow.  If the float is working properly and your dishwasher over fills with water, it could be that the float switch has failed.  You can test the float switch for continuity, If the switch has continuity it is good.  If it does not, the switch is bad and will need to be replaced to fix the problem.

Troubleshooting tip – A test meter can be a real time and money saver while troubleshooting the numerous electrical parts on a dishwasher.  Electrical parts can be diagnosed either bad or good quickly, instead of assuming that a dishwasher’s electrical part is faulty and replacing it, only to find out that the part wasn’t bad and the problem lies elsewhere with another broken dishwasher part.  If you don’t have a test meter, a digital meter can be purchased reasonably cheap online or from one of your local hardware stores.
