If your Maytag dishwasher is not working, there are a few things you can check before calling a repairman. First, make sure the unit is properly plugged in or, if it's directly wired, that the wiring has been correctly connected. Next, check that the door is securely closed and the water supply is on. If your dishwasher is hardwired, you can reset it by turning off the breaker for one minute and then turning it back on. If your dishwasher still won't start, you can test the door latch assembly and timer using a multimeter. If the problem is more complex, such as a faulty drive motor or failing electrical components, you may need to schedule an appointment with a professional.

What You'll Learn
Check if the dishwasher is plugged in or hardwired
To check if your Maytag dishwasher is plugged in or hardwired, follow these steps:
First, turn off the dishwasher. This is crucial for your safety during the inspection process. Once the dishwasher is off, carefully unplug it from the electrical outlet if it is plugged in. If there is no power cord or plug visible, your dishwasher is likely hardwired.
Next, gently pull out the dishwasher from its usual space. Be cautious not to damage any surrounding cabinets or countertops during this process.
Now, inspect the back of the dishwasher. If you notice a power cord with a plug attached, your dishwasher is not hardwired. It is simply connected to a power outlet via the plug. In this case, it can be easily disconnected and moved if needed.
On the other hand, if you do not see a power cord or plug, your dishwasher is likely hardwired. Look for a metal junction box behind the dishwasher. This box serves as the connection point between the dishwasher and your home's electrical system. It may be screwed into the wall or attached using other fasteners.
If you observe a direct electrical connection within the junction box, your dishwasher is indeed hardwired. These wires are often encased in plastic insulation for protection against electrical currents. There may also be wire nuts or other types of connectors securing the connections.
Remember, if you are unsure or uncomfortable handling electrical components, it is always best to consult a professional electrician for guidance.

Test the thermal fuse with a multimeter
If your Maytag dishwasher is not working, it could be due to a faulty thermal fuse. To test the thermal fuse with a multimeter, follow these steps:
Step 1: Safety First
Before you begin, ensure that the power to the dishwasher is turned off at the fuse box to prevent any electrical shocks.
Step 2: Access the Thermal Fuse
The thermal fuse is usually located near the control panel or the door of the dishwasher. Refer to your dishwasher's manual or seek model-specific instructions online to locate the thermal fuse in your Maytag dishwasher.
Step 3: Set Up the Multimeter
Set your multimeter to measure resistance or ohms. This setting is often denoted by the symbol Ω. Touch the multimeter probes together to ensure it reads zero or close to zero ohms.
Step 4: Test the Thermal Fuse
Locate the two metal ends of the thermal fuse, which are the connection points. Touch one probe of the multimeter to one end of the thermal fuse, and touch the other probe to the other end. The multimeter should read zero or close to zero ohms, indicating continuity. If it reads OL (over limit) or has a very high resistance reading, the thermal fuse is blown and needs to be replaced.
Step 5: Further Diagnostics
If the thermal fuse tests fine, you may need to test other components, such as the heating element or the temperature sensor, to identify the root cause of the issue. Refer to your dishwasher's schematic diagram to identify these components and their test procedures.
Please note that working with electricity can be dangerous. If you are unsure or uncomfortable at any point, it is best to consult a qualified technician.

Verify the water supply
If your Maytag dishwasher is not filling with water, there are a few things you can check to verify the water supply.
First, ensure that the water supply valve is turned to the open position. The water supply valve is usually located under the sink. Twist the valve to allow water to flow freely through the water supply line and into the dishwasher. Consult your appliance's user manual to confirm the location of the valve and ensure that it is not leaking or blocked. If there is a leak, place a bucket under the valve and use a wrench to tighten all connections.
Next, check the water inlet valve, which is typically found on the lower left side of the dishwasher, behind the lower access panel. The water inlet valve controls the amount of water entering the dishwasher and has two wires attached, an outlet hose to the tub, and a hot water inlet from the household supply. Inspect the water inlet valve for any signs of damage, wear, or cracking. If the valve appears damaged, you may need to replace it.
Additionally, verify that the door switch is functioning properly. The door switch is an on/off mechanism that prevents the dishwasher from operating when the door is open. To test the door switch, unplug the appliance, separate the inner door from the outer door, and locate the switch, usually behind the door panel at the top of the door. Remove the door switch and test for continuity using a multimeter.
Finally, inspect the float switch, which prevents the dishwasher from overfilling with water. Open the dishwasher door and remove the cover over the float assembly. Manually lift the float and let it drop multiple times to ensure it moves freely. If it doesn't, remove any foreign objects in the guide tube and inspect the float for any visible wear or damage.

Check the door latch
If your Maytag dishwasher is not starting or operating, it could be due to a faulty door latch. The door latch is a simple on/off mechanism that prevents the dishwasher from operating when the door is open. It is located at the top of the door and locks the door shut when the dishwasher is running.
To check the door latch, first, ensure that the door is securely closed. If the door is not properly closed, the latch may need to be adjusted or replaced. If the door is damaged, changing the latch could be the solution.
To replace the door latch, follow these steps:
- Disconnect the power from the dishwasher.
- Remove all screws from the inner panel.
- Lift up the inner door panel and hold the door apart.
- Access the latch and pull wires from the switches, following the instructions in the manufacturer's manual.
- Install the new latch by reconnecting the wires and screwing the inner panel back in place.
It is important to note that you should always unplug the dishwasher from the power source or shut off the house circuit breaker before beginning any installation or repair work. Additionally, make sure to inspect the door hinges, door strike assembly, and door spring tension for any damage that may be causing the door latch issue.

Test the timer with a multimeter
If your Maytag dishwasher won't start, the problem could be with the door latch or door latch switches. Before you begin testing the timer with a multimeter, disconnect your appliance from its power source.
To test the timer, first locate and remove it. The timer is usually found in the control panel, but it may also be behind the lower kick plate. If your timer has multiple sets of contacts/wires, refer to your wiring diagram to determine which contacts to test. Set your multimeter to Rx1000 and touch the contacts with the probes. A functioning timer will typically fall within the range of 2000-3500 ohms of resistance, but this can vary between models. Check your owner's manual to see what reading your test should produce. If your test results differ from the manufacturer's recommendations, you will need to replace the timer.
If your dishwasher still won't start after testing the timer, you can also test the thermal fuse with a multimeter. Set the multimeter to Rx1 and touch the fuse's contacts with the probes. You are testing for continuity and should receive a reading of zero or close to zero. If you don't get this reading, you will need to replace the thermal fuse.
If the dishwasher still won't start, the problem could be with the drive motor. To test this, disconnect the dishwasher from its power source. Set the multimeter to Rx1 and touch the contacts with the probes. If the dishwasher won't start after the start relay sends power to the motor, this could indicate a defective drive motor, which will need to be replaced.
