Do you have a dishwasher that you're currently unable to use? It seems to be on, but for some reason, that start button just isn't working. Before you call for help, it's important to find out the potential reason if you can so that you know what you are dealing with. Here are the most common reasons for a dishwasher not starting.
Check the Wiring and Fuses
This can sound like a silly suggestion, but it is one that is commonly forgotten now. People jump to the technology not working, but it could be something as simple as faulty wiring or a blown fuse. Check these elements before you start pulling the dishwasher apart!
The Door Isn't Latching
If the door to the washer doesn't close, it isn't going to start. This is a fail-safe to prevent water from flooding your kitchen. So, you need to check if the door is latching—actually listen out for it catching when you close it. Some dishwashers have a light to warn you that it isn't closed.
In some cases, the door latches but the dishwasher doesn't realize. This is when there is a fault somewhere within the electronics. The manual will help you determine where the latch switch is and troubleshooting the exact problem.
Timer Controls Broken
When the door latch isn't the problem, you want to listen out for the sound of the motor for the drain pump working. If this doesn't happen, there is a sign that your time control is broken. The timer is connected to all other elements that make the dishwasher work and is a common feature to stop working without warning.
The timer will use some electrical contacts within the dishwasher. If any of these are disconnected, the starter isn't going to work.
Check for Any Jams
In some cases, you'll hear the motor trying to work but it just whines and stops. This suggests that there is a jam somewhere along the way, and you need to get inside to look for anything that could possibly stop your machine from working. Check the motor to see that nothing is stopping it from moving and look at the drive belt for any sign of damage.
These are among the most common reasons for a dishwasher not to start. By checking these first, you could save yourself a lot of money because you won't need to call a plumber out to fix the issues.
