A dishwasher that won’t start can be a frustrating experience after a holiday dinner with a large family. However, if you consider yourself somewhat handy, instead of washing all those dishes by hand, you may want to try fixing the issue yourself. Here’s everything you need to know to troubleshoot and fix a dishwasher that won’t start.
Please read our article to learn more about what to do if the dishwasher won’t turn on and what you can do about it.
Common Reasons Why Your Dishwasher Won’t Turn On
Before you can make any attempt to repair a dishwasher that would not start, you have to figure out the reason for the problem. Several different issues can arise, preventing your dishwasher from operating. Here are some of the more common possibilities.
The Door Latch May Be The Reason Your Dishwasher is Not Turning On
When you close your dishwasher’s door, the latch engages, sending a signal through a circuit board that lets the appliance know that it’s safe to start the motor and begin the washing cycle. If the machine doesn’t start, you’ve tried resetting the power, and you’re still having no luck, your door latch may not be engaging.
To test this theory, you should first examine the latch visibly for obvious signs of wear. If it looks okay, that doesn’t mean it’s working as it should. Next, try pushing the latch mechanism with your fingers. If it seems to resist your efforts or sticks a little, you may still have a problem with the latch that’s preventing your machine from starting to run.
If Your Dishwasher Won’t Start But Has Power, it Could Be The Selector Switch.
Most modern dishwashers have multiple settings. These usually allow us to change our options for heavy-duty cleaning versus lighter cleaning duties, heated cleaning, etc. To change the options available to the operator, your dishwasher uses a selector switch.
If this selector switch stops working correctly, your appliance doesn’t get the signal to begin. Suppose your machine has buttons that allow you to select the setting. Check to see if one of them is sticking and try to return it to the off position. Then, test a setting again. If the machine starts, your issue is the button that’s not disengaging properly.
You May Have a Faulty Timer When the Dishwasher Light’s On But Won’t Start
You may see your dishwasher light up as it should, but it won’t start. One other common problem that may prevent it from operating is the timer. Your dishwasher goes through different functions as it cycles. That starts with the appliance draining any standing water left over from the last time you used it. So, if you don’t hear the machine begin to drain when you start it up, the timer may not signal the dishwasher to start the process and begin cleaning.
What to Do When Your Dishwasher Doesn’t Run
A dishwasher is a major appliance like any other. That means many moving parts and circuit boards play a role in how it operates. If you’re not confident in your ability to work with these types of components, it’s always best to leave the repair attempts to professionals. However, for those with the basic knowledge needed to try, here are the methods you might use to fix the problems mentioned above yourself.
Repairing Your Dishwasher’s Door Latch
To repair or replace a door latch on a dishwasher, you’re going to need a screwdriver. You’ll need it to remove the inner door panel to access the latch and latch assembly. The latch uses a switch that communicates with a circuit board through connecting wires. If you’re uncomfortable working with electrical components, it’s best to reach a qualified repair company.
The first step is to test-check the switch to ensure it engages with the wires. If it isn’t, it’s the source of your problem. Assuming the switches are working as they should and the latch seems to be engaging, you may have a problem with power from the switch to the wires. You can use a multimeter to test this. Once you’ve identified which part of the process is causing the problem, you can replace that component.
Fixing a Selector Switch in a Dishwasher
Fixing a selector switch will also require removing the inner panel to access the switch. Once you remove the panel, you can use the multimeter we mentioned above to test for power between the switch and its connectors. If there’s no power, it probably needs to be replaced. Again, always opt for safety first if you’re uncomfortable working with electrical components. Contact the professionals at FIX Appliances CA for help.
How to Replace a Faulty Timer in a Dishwasher
The timer in your dishwasher is one of the more complicated components to replace. In most modern dishwashers, the circuit board and microprocessor control the timing function of your machine. Unfortunately, this isn’t an easy fix, so unless you’re a qualified technician, we don’t recommend attempting this repair on your own.
