When a Frigidaire dishwasher displays the error code 40, it can leave users feeling perplexed and frustrated. In this comprehensive guide, we will explore what Code 40 means, what potential problems it indicates, and how to troubleshoot these issues effectively. Whether you’re a seasoned appliance user or new to home maintenance, understanding this error code can save you time, money, and stress.
What Does Error Code 40 Mean?
The error code 40 on a Frigidaire dishwasher typically indicates a malfunction related to the wash motor or issues with water circulation. This code signifies that an internal problem has occurred, preventing the washer from completing its cycle efficiently. Most often, this code is triggered by one of the following reasons:
- Blocked or Clogged Filters: Food particles, grease, and other debris can clog the dishwasher’s filters, hampering water flow and leading to error code 40.
- Malfunctioning Wash Motor: If the wash motor that circulates water for cleaning purposes is faulty or has failed, the dishwasher may display this error code.
Understanding what could be causing the error code 40 is the first step in finding a solution.
Common Causes of Error Code 40
To effectively address the issue represented by code 40, it is essential to diagnose the underlying cause. Each possible cause comes with its own set of symptoms and solutions.
1. Blocked or Clogged Filters
Clogged filters can restrict proper water circulation within your dishwasher, causing the error code to appear. Dishwashers have several filters, including:
- Fine Filter: Captures small food particles.
- Coarse Filter: Prevents larger items from causing blockages.
If the filters are dirty, they can impede proper water flow, resulting in the error code.
2. Faulty Wash Motor
The wash motor powers the spray arms that distribute water throughout the dishwasher. If this component fails or operates inefficiently, it can trigger the error code 40. Symptoms of a failing wash motor may include unusual noises during operation, erratic spray patterns, or the complete absence of water circulation.
3. Wiring or Connection Issues
Loose connections or damaged wiring can inhibit the proper functioning of the wash motor. If the dishwasher’s motor does not receive the required electrical signals, it may not operate correctly, leading to the appearance of the error code.
4. Electronic Control Board Problems
The electronic control board is the brain of the dishwasher. If it malfunctions, it can fail to send the appropriate signals to the motor, resulting in error code 40. This situation often requires professional assessment.
How to Diagnose Error Code 40
To properly address the error code 40, follow these diagnostic steps:
Step 1: Inspect the Filters
- Unplug the Dishwasher: Always ensure that the dishwasher is disconnected from power before performing maintenance.
- Locate the Filter: Depending on your Frigidaire model, you may find the filters at the bottom of the dishwasher.
- Clean the Filters: Remove any debris, food particles, or grease build-up. Use warm, soapy water to clean the filters and rinse them thoroughly before reinstallation.
Step 2: Assess the Wash Motor
- Check for Obstructions: Inspect the spray arms for clogs or blockages. Remove any items that may be lodged inside them.
- Listen for Noises: Turn the dishwasher back on and listen for unusual sounds that might indicate a malfunctioning wash motor.
- Test the Motor: If you feel comfortable, you can test the motor using a multimeter to check for continuity. If there is no continuity, it may need to be replaced.
Step 3: Inspect Wiring and Connections
- Visual Inspection: Look for any visible signs of wear, fraying, or loose connections related to the wash motor and control board.
- Reconnect Loose Wires: Make sure that all connections are tight and secure.
Step 4: Check the Control Board
- Visual Damage: Inspect the electronic control board for burned-out components or physical damage.
- Consult a Professional: If the board shows signs of failure, it is advisable to consult a technician.
Fixing Error Code 40
Once you have diagnosed the issue, the next step is addressing the problem effectively.
Cleaning and Maintenance
Preventative maintenance is the best approach to avoiding error code 40 in the future. Here are some maintenance practices you should adopt:
Regular Filter Cleaning
Clean the filters at least once a month to prevent clogs. A routine check can help ensure that the dishwasher runs smoothly.
Inspect Spray Arms
Periodically check the spray arms for any signs of clogging. Ensure that the arms can rotate freely without obstruction.
Repair or Replace Components
In circumstances where issues with the wash motor, wiring, or control board are identified, you may need to replace damaged parts. Here’s what to consider:
Wash Motor Replacement
If testing reveals that the wash motor is faulty, obtaining a replacement part may be required. Ensure that you purchase the correct motor model compatible with your specific dishwasher.
Consulting a Professional
If you’re uncomfortable tackling repairs on your own, or if the issue persists despite your attempts at troubleshooting, it’s wise to contact a professional appliance repair technician. They are equipped to handle repairs reliably and safely.

What does Code 40 mean on a Frigidaire dishwasher?
The Code 40 on a Frigidaire dishwasher typically indicates a malfunction related to the dishwasher’s heating element or temperature sensor. This error code is a signal that the appliance is encountering issues during the wash cycle, particularly when trying to achieve or maintain the correct water temperature. When this code appears, it is crucial to address it promptly to avoid further complications.
This error can be caused by various factors, including a defective heating element, a malfunctioning thermostat, or wiring issues within the dishwasher. Identifying the specific cause of the problem is essential before attempting any repairs, as it might involve testing different components to ensure that everything is functioning properly.
How can I troubleshoot Code 40 on my Frigidaire dishwasher?
To troubleshoot Code 40, start by resetting the dishwasher. You can do this by unplugging the appliance for a few minutes or switching off the circuit breaker. Once power is restored, run a short cycle to see if the error code reappears. This simple step may clear any temporary glitches causing the malfunction.
If the error persists, check the heating element for signs of damage or wear. Use a multimeter to test the resistance of the heating element, ensuring it has continuity. Additionally, inspect the temperature sensor to see if it’s functioning correctly, as a faulty sensor can also trigger Code 40. If you aren’t comfortable performing these checks, it may be best to call a professional technician for assistance.
What should I do if the Code 40 persists after troubleshooting?
If the Code 40 still appears after you have performed basic troubleshooting steps, you may need to consider more in-depth diagnostic work. At this point, it could be indicative of a more serious issue within the dishwasher’s heating and electrical systems. This may involve checking the wiring connections and ensuring that there are no shorts or breaks that could affect the components involved.
In some cases, it might be necessary to replace parts such as the heating element or the control board if they are found to be defective. Consulting the dishwasher’s user manual for service instructions can provide further insights. If you’re not experienced in appliance repair, it’s advisable to enlist the help of a professional repair service to prevent any potential damage.
Can I fix Code 40 myself or should I hire a professional?
Whether you can fix Code 40 yourself depends on your comfort level and experience with appliance repair. For those who are handy and familiar with electrical work, troubleshooting the issue by testing the heating element and temperature sensor might be manageable. Just make sure to follow safety protocols, such as disconnecting power before working on the appliance.
However, if you feel uncertain about performing repairs, or if you’ve already tried basic troubleshooting without success, hiring a professional is a prudent choice. Professional technicians have the tools and expertise to accurately diagnose and repair issues, ensuring that your dishwasher operates safely and effectively once again.
How much does it cost to repair a dishwasher with Code 40?
The cost to repair a dishwasher displaying Code 40 can vary widely depending on the underlying cause of the error and the components that need replacement.
