Dishwasher Control Board 101: Beginners Guide

The dishwasher control board, often referred to as the electronic control board or main control board, is a critical component that plays a central role in the operation of your dishwasher.

Understanding what the control board does, why it may fail, whether it can be replaced, its lifespan, and the cost of replacement are essential aspects for homeowners seeking to maintain their dishwashers efficiently.

What is a Dishwasher Control Board?

The dishwasher control board is essentially the brains behind the operation of your dishwasher. It serves as the control center that manages and coordinates various functions of the appliance, such as the wash cycles, water temperature, and duration.

Modern dishwashers are equipped with advanced control boards that feature digital displays and touchpad interfaces, making it easy for users to select different settings and monitor the progress of a wash cycle.

Common Causes of Control Board Failures

Dishwasher control boards can fail for various reasons, and understanding these common causes can help you prevent issues and prolong the lifespan of your appliance:

Electrical Surges: Power surges or voltage fluctuations can damage sensitive electronic components on the control board, leading to malfunctions.

Moisture and Humidity: Dishwashers create a humid environment, and if moisture penetrates the control board, it can cause corrosion or short circuits.

Age and Wear: Over time, the control board can naturally deteriorate due to continuous use, which may result in component failure.

Manufacturing Defects: Occasionally, control boards may have manufacturing defects that become apparent after some time in operation.

Can a Dishwasher Control Board Be Replaced?

Yes, a dishwasher control board can be replaced. However, it’s essential to note that this is a job best left to professionals, as it involves working with electricity and intricate components.

Replacing the control board typically involves the following steps:

Disconnecting power: Ensure the dishwasher is unplugged or disconnected from the electrical supply.

Removing the front panel: Access the control board by removing the front panel of the dishwasher.

Disconnecting wires: Carefully disconnect the wires and connectors from the old control board.

Installing the new board: Insert the replacement control board and reconnect the wires and connectors.

Reassembling: Reassemble the front panel and restore power to the dishwasher.

Lifespan of a Dishwasher Control Board

The lifespan of a dishwasher control board varies depending on several factors, including the brand, model, usage, and maintenance. On average, you can expect a control board to last anywhere from 5 to 15 years.

Regular maintenance, such as cleaning the dishwasher’s interior, avoiding overloading, and addressing issues promptly, can help extend its life.

Worth Replacing a Dishwasher Control Board?

Whether it’s worth replacing a dishwasher control board depends on several factors:

Age of the dishwasher: If your dishwasher is relatively new and in good condition otherwise, replacing the control board may be a cost-effective solution.

Cost of replacement: The cost of a new control board can vary significantly depending on the make and model of your dishwasher. Be sure to get a quote for the replacement part and labor costs.

Overall condition: Consider the overall condition of the dishwasher. If it has multiple issues or is nearing the end of its lifespan, it may be more cost-effective to invest in a new dishwasher.

Personal preference: Some homeowners may prefer to repair and extend the life of their appliances, while others may opt for a new, more energy-efficient model.

How Much Does it Cost to Replace a Dishwasher Control Board?

The cost of replacing a dishwasher control board can range from $100 to $300 or more, depending on the brand and model of your dishwasher and whether you choose to hire a technician for the installation.

Labor costs can also vary, so it’s advisable to obtain quotes from reputable repair service providers in your area.

Final Thoughts

The dishwasher control board is a vital component that influences the functionality of your dishwasher. While it can fail due to various factors, it is replaceable.

Whether or not it’s worth replacing depends on factors such as the age and overall condition of your dishwasher, the cost of replacement parts, and your personal preferences.

Regular maintenance and prompt attention to issues can help prolong the lifespan of your dishwasher control board, ensuring your appliance continues to serve you efficiently for years to come.
