How to Test and Change the Resistance of a Steamer and Iron

Aug 03, 2023, 15:16pm

The steam station, or iron, uses water vapor to iron clothes. The water coming from the tank passes through a heating circuit which transforms the droplets into vapour. This heating is done thanks to the resistance, the main heating element of the device.

The resistance is a part that can wear out quickly, because it can be in contact with water and is often stressed.

The resistor can be the cause of the following failures:

  • The steam generator does not heat up or not enough.
  • Steam does not come out.
  • The iron trips the electrical installation.

There are two resistors in the device:

one in the steam plant at the level of the boiler and another in the iron.

An essential part of any household’s laundry arsenal is a good quality steamer or iron. These appliances make our clothes look crisp, neat, and well maintained. The effectiveness of your steamer or iron largely depends on a critical component known as the heating element or the resistance. This component is responsible for heating the water to create steam or heat the iron’s plate. Over time, this element can wear out or malfunction, affecting the appliance’s overall performance. This article will guide you through the process of testing and replacing the resistance of a steamer or iron.

Signs of a Malfunctioning Resistance

Before proceeding to test and change the resistance, it is essential to identify signs that may indicate a faulty resistance. Here are some common signs:

  1. Inadequate Heating: If your steamer or iron does not heat up adequately or takes a long time to heat, it may be due to a malfunctioning resistance.
  2. Inconsistent Temperature: If the temperature fluctuates while in use, the resistance might be faulty.
  3. No Power or Heat: If the iron or steamer does not power up or fails to heat, the resistance may be completely broken.

How to Test the Resistance

Step 1: Safety Precautions

First and foremost, safety is paramount. Always ensure the steamer or iron is unplugged before you begin testing.

Step 2: Access the Resistance

Locate the resistance, which usually lies beneath the base plate of the iron or the heating chamber of the steamer. You may need to unscrew the base or cover to access it.

Step 3: Test the Resistance

To test the resistance, you will need a multimeter, a tool that measures electrical properties like voltage, current, and resistance. Set the multimeter to the resistance setting (often denoted by the Greek letter Omega Ω) and connect the probes to each terminal of the heating element.

The correct resistance reading will depend on the specific model of your iron or steamer, so refer to your user manual for this information. If the reading on your multimeter significantly deviates from the manual’s value, your resistance is likely faulty and needs replacing.

How to Change the Resistance

Step 1: Procure a Replacement

Once you have determined that your resistance is faulty, you will need to purchase a replacement. Make sure to choose a part that is compatible with your specific model of steamer or iron.

Step 2: Replace the Resistance

Unscrew the faulty resistance and carefully disconnect it from any wires. Connect the replacement resistance to the wires and screw it into place. Be careful to ensure all connections are secure and that the replacement part is correctly installed.

Step 3: Test the Appliance

After replacing the resistance, it’s time to test the appliance. Plug it in and turn it on, then let it heat up for a few minutes. If the iron or steamer heats up correctly and maintains a consistent temperature, you have successfully changed the resistance.


A faulty resistance can greatly affect the performance of your steamer or iron. Understanding how to test and change this crucial component can help maintain your appliance’s efficiency and prolong its lifespan. Remember to always prioritize safety when handling electrical appliances, and if you’re uncertain about any part of the process, don’t hesitate to consult a professional. Regular maintenance can save you from unnecessary costs and ensure that your clothes are always at their best.
