Troubleshoot Why A Dishwasher Overflows With These 2 – Steps

Step-1. Water Inlet Valve

The water inlet valve is used to supply the dishwasher with the correct amount of water for the wash cycle, then shut off.  Repair Tip – A bad water inlet valve could be the reason why your dishwasher is over flowing with water.  If the inlet valve is faulty or malfunctioning, it can stay partially open, allowing water to continue entering the dishwasher, even when the dishwasher is not in use.

Step-2. Float Switch

Troubleshooting The float switch assembly, it is 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 dishwasher tub, the switch is then activated, shutting the flow of water off.  If the float gets stuck, it will not rise with the water and the switch will not be activated, causing the dishwasher to overfill with water.  If the float is working properly and your dishwasher overfills, it could be that the float switch has failed.  You can test the float switch for continuity using a multimeter, If the test shows the switch has continuity it is good.  If it does not, the part is faulty 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.
