What are error codes?

Appliance error codes show up as alphanumeric combinations on the appliance’s control panel or a digital display. The codes may be displayed on a digital readout or as a set of specific flashing lights that need to be interpreted. You may also have to access these flashing codes by putting the machine into a diagnostic test mode.

Error codes are designed to provide information about problems with specific parts or other malfunctions that the appliance has encountered. These codes help direct users and technicians to the underlying problem so they can take the appropriate action(s) to resolve it. Though no one wants to see an error code on their machine, they’re a great diagnostic tool that narrows down the problem so you can troubleshoot and fix it faster.

Generally, error codes can indicate issues like faulty parts, sensor glitches, communication problems and power supply irregularities. The meanings also vary depending on the appliance brand and model, so if you have access to your machine’s tech sheet, user manual or other documentation, it’s best to refer to them for more specific information.

If you look at your machine’s tech sheet, listed error codes are typically accompanied by a brief description of the issue and steps to resolve it.

How many types of error codes are there?

This varies by type of appliance and its manufacturer. While some error codes are common across multiple appliances or brands, others are specific to a particular make and model, as each can have its own unique set of codes.

Generally, most error codes can be broadly categorized into various types such as electrical, sensor, communication, mechanical or operational errors. The specific categories and the number of error codes within each category depend on the complexity and features of the individual appliance.

Do all appliances display error codes?

No. The presence of error codes depends on the specific design and features of each appliance. You can usually find error codes on larger, more complex appliances such as refrigerators, washing machines, dishwashers, ovens, dryers or air conditioning systems to aid in troubleshooting.

Simpler and smaller appliances like older, more basic microwave ovens or toasters may not always have error code displays. To troubleshoot these appliances, you’ll usually just have to visually inspect them and check for connectivity or power issues.

If you encounter a problem with an appliance that doesn’t display error codes or a set of flashing lights, your appliance may not have an error display system. This is especially true for older appliances that were manufactured before the late 1990s.

What are the most common types of error codes?

These are some of the most common types of error codes that users can encounter in most major home appliances:

Temperature-related errors

These types of error codes often indicate issues with temperature sensors, heating elements or cooling systems. They usually occur in appliances like refrigerators, ovens, or air conditioners.

Water supply-related errors

These codes may display on appliances such as washing machines, dishwashers or refrigerators and typically signify problems with the water supply like filling, drainage or pressure sensors.

Electrical errors

Electrical codes signify issues with the power supply to an appliance or its internal parts or circuitry. These errors can occur in any machine with an error code system.

Communication errors

These codes suggest an appliance’s parts are having trouble communicating with other parts or systems within it. They can occur in appliances with advanced features or network connectivity.

Mechanical errors

These codes highlight mechanical malfunctions such as motor failures, jammed parts or blockages. They are often encountered in appliances with moving parts.

Refer to the user manual and technical sheet

Your appliance’s user manual and technical sheet are valuable resources with information about error codes that are specific to your model. Look for a troubleshooting section or an error code table that explains the meaning of each code and provides recommended steps to resolve them. If you don’t have a user manual or it’s missing, you may be able to find it online by visiting the manufacturer’s website.

Check for damage, clogs and other obvious issues

When you check your machine, always start with the easiest checks before you dig deeper into the troubleshooting process. This keeps things simple and helps prevent any missteps that could lead you to think a well-functioning part needs to be replaced.

Start by inspecting the appliance for any visible damage or obvious problems like clogs. Some basic checks you can do yourself include looking for loose connections, damaged wires, or clogged filters. Sometimes addressing these simple issues is all it takes to resolve the error code.

For example, if an error code shows up on your dryer, you should double-check your venting system and lint filter for any blockages that could hinder airflow before you take the machine apart.

Reset the power

In some cases, if the error code is related to a temporary power-related issue (like after an outage), a simple power reset (also called power cycling) may be able to clear it.

To power cycle your appliance, turn it off and unplug it from the power source. Wait a few minutes, then plug it back in and turn it on.

Enter diagnostic mode

Some appliances have a diagnostic mode that allows you to run internal tests or retrieve more detailed error information so you can fix it. To enter diagnostic mode, you may have to press a certain combination of buttons or turn dials to a certain setting. Refer to the technical sheet to learn more about how to access diagnostic mode on your machine.

How can I prevent error codes from displaying on my appliances?

While it’s not always possible to prevent error codes from occurring, you can take certain preventive measures to reduce the likelihood of encountering them:

  • Make sure your appliances are installed correctly and according to the manufacturer’s instructions.
  • Perform regular cleaning and maintenance that may include cleaning filters, inspecting and tightening connections and replacing worn-out parts. You can usually find more maintenance tips in the machine’s user manual.
  • Always follow the manufacturer’s guidelines for using the appliance. Avoid overloading, using incompatible accessories or subjecting the appliance to conditions (e.g., outdoor use) it’s not designed for.
  • Keep the appliance connected to a stable and appropriate power source. Voltage fluctuations or irregularities in the power supply can cause error codes and more serious problems that require costly replacements. Consider using good-quality surge protectors or voltage stabilizers if necessary.
  • Keep the appliance clean to prevent dirt, lint, debris or dust from accumulating and making their way into sensitive parts. Clean appliances also have a significantly lower risk of catching fire.
  • Regularly check for any firmware or software updates for your appliance from the manufacturer. These updates may address known issues or improve the appliance’s performance, which can reduce the occurrence of error codes.
