Have you ever been in a situation where you’re all set to clean up after a delicious meal, only to find that your Maytag dishwasher MDB7749SBM3 refuses to start? It can be frustrating, to say the least. But fear not! In this blog post, we will explore some common reasons why your dishwasher might not be starting and provide you with practical solutions to get it up and running again. So, let’s dive right in and troubleshoot this issue together!
Check the Power Supply
Is your dishwasher plugged in? It may seem obvious, but sometimes the simplest solutions are the most effective. Ensure that your Maytag dishwasher is properly plugged into a functioning power outlet. If it is, move on to the next step.
Reset the Circuit Breaker
Sometimes, a tripped circuit breaker can cause your dishwasher to refuse to start. Locate your home’s electrical panel and check if any breakers have been tripped. If you find one that corresponds to your dishwasher, flip it off and then back on. This simple reset might just do the trick!
Examine the Door Latch
The door latch is a safety feature that prevents the dishwasher from starting if the door is not securely closed. Give the door a firm push to ensure it is fully closed and latched. If the latch is damaged or misaligned, you may need to replace it. However, before jumping to conclusions, let’s explore other possibilities.
Check the Control Panel
The control panel is the brain of your dishwasher, and if it’s not functioning correctly, your dishwasher won’t start. Look for any error codes or indicator lights on the panel. If you notice any, consult your dishwasher’s manual for troubleshooting instructions. In some cases, a simple control panel reset might be all that’s needed.
Inspect the Door Switch
The door switch is another safety feature that signals to the dishwasher that the door is closed. Over time, the switch can become worn out or damaged, resulting in a dishwasher that won’t start. To check the door switch, you’ll need to remove the inner door panel. If you’re not comfortable doing this yourself, it’s best to call a professional technician.
Test the Thermal Fuse
The thermal fuse is a small device that prevents your dishwasher from overheating. If the thermal fuse is blown, your dishwasher won’t start. Use a multimeter to test the thermal fuse for continuity. If it’s faulty, replace it with a new one.
Check the Motor Start Relay
The motor start relay is responsible for sending power to the dishwasher’s motor. If it’s defective, your dishwasher won’t start. Test the relay using a multimeter. If it fails the test, you’ll need to replace it.
Inspect the Control Board
The control board is the heart of your dishwasher’s electrical system. If it’s malfunctioning, your dishwasher may refuse to start. Look for any signs of damage or burnt components on the control board. If you spot any, replacing the control board may be necessary.
Examine the Wiring
Loose or damaged wiring can disrupt the electrical flow and prevent your dishwasher from starting. Inspect the wiring connections and look for any signs of wear or damage. If you find any issues, repair or replace the wiring as needed.
Clean the Float Switch
The float switch is a small device that detects the water level in your dishwasher. If it’s stuck or obstructed, your dishwasher may not start. Locate the float switch, clean it, and ensure it moves freely.
Check the Water Inlet Valve
The water inlet valve controls the flow of water into your dishwasher. If it’s faulty or clogged, your dishwasher won’t start. Inspect the valve for any blockages or signs of damage. If necessary, clean or replace the water inlet valve.
Test the Door Switch Assembly
The door switch assembly consists of multiple switches that work together to ensure the door is closed properly. If any of these switches are faulty, your dishwasher may not start. Test each switch using a multimeter and replace any that are defective.
Evaluate the Control Panel Buttons
The control panel buttons can become unresponsive over time due to wear and tear. If certain buttons are not working, it may prevent your dishwasher from starting. Clean the buttons and check for any visible damage. If necessary, replace the control panel.
Call a Professional Technician
