Washing Machine Tachometer: Beginners Guide 101

Washing machines have come a long way in terms of technology and efficiency, and one crucial component that plays a significant role in their operation is the washing machine tachometer.

In this article, we’ll delve into what a washing machine tachometer is, why it’s essential, reasons for failure, repair or replacement options, and the associated costs.

What Is a Washing Machine Tachometer?

A washing machine tachometer, often referred to as a “tacho,” is a small but critical component of the machine’s motor control system.

It’s essentially a sensor that monitors the speed of the motor shaft as it rotates.

This information is crucial for the machine’s control board, allowing it to regulate various functions such as the wash cycle, spin cycle, and water intake.

Why Are Tachometers Important?

Tachometers play a vital role in maintaining the balance and stability of a washing machine during operation. Here are a few reasons why they are important:

  • Speed Regulation: Tachometers ensure that the motor runs at the correct speed, ensuring that the drum rotates at the desired speed during different cycles, like washing and spinning.
  • Load Balancing: They help the machine adjust its operation according to the load’s weight and distribution, preventing excessive vibrations and uneven spinning.
  • Energy Efficiency: By monitoring and adjusting the motor speed, tachometers help optimize energy consumption during each wash cycle.

Why Do Tachometers Fail?

Like any mechanical or electrical component, washing machine tachometers can fail over time. Common reasons for their failure include:

  • Wear and Tear: Continuous use can lead to wear and tear, causing the tachometer to malfunction.
  • Electrical Issues: Voltage spikes or power surges can damage the tachometer’s circuitry.
  • Moisture and Corrosion: Moisture infiltration due to leaks or spills can damage the tachometer’s internal components.
  • Manufacturing Defects: In rare cases, manufacturing defects can lead to premature tachometer failure.

Can Tachometers Be Repaired?

Repairing a tachometer is possible in some cases, especially if the issue is minor. Here are the steps to consider if you suspect a tachometer problem:

Diagnosis: First, identify if the tachometer is the issue. This may require professional diagnostics or a multimeter to test for continuity.

Cleaning and Inspection: Sometimes, a thorough cleaning and inspection can resolve minor issues caused by dirt or corrosion.

Component Replacement: If specific components within the tachometer are damaged, you can try replacing them. However, this may require technical expertise.

Can Tachometers Be Replaced?

Yes, tachometers can be replaced. Replacement is often the preferred solution if the tachometer is significantly damaged or beyond repair. Here’s what you should do:

  • Identify the Correct Replacement Part: Ensure you have the correct tachometer model compatible with your washing machine.
  • Disconnect Power: Before starting any replacement procedure, unplug the washing machine from the power source to ensure safety.
  • Access the Tachometer: Depending on your washing machine model, you may need to remove the back panel or access the motor area to reach the tachometer.
  • Replace the Tachometer: Carefully disconnect and replace the old tachometer with the new one, following the manufacturer’s instructions.

Are Tachometer Replacements Expensive?

The cost of a replacement tachometer can vary depending on the washing machine’s brand and model.

Typically, the cost of the part itself is reasonable, ranging from $20 to $50.

However, labor costs for professional installation may add to the overall expense.

Can You Replace a Tachometer Yourself?

Replacing a washing machine tachometer is a task that can be completed by a moderately skilled DIY enthusiast, provided you have the right tools and follow safety precautions.

If you’re confident in your abilities, you can save money by doing it yourself.

However, if you’re unsure or uncomfortable with appliance repair, it’s best to hire a professional technician to avoid any mishaps.

Final Thoughts

Washing machine tachometers are essential for ensuring the proper functioning and longevity of your appliance.

Understanding their role, the reasons for failure, and your options for repair or replacement can help you maintain a smoothly operating washing machine.

Whether you choose to repair or replace a faulty tachometer, always prioritize safety and consider seeking professional assistance when needed.
