Zojirushi Water Boiler Descaling Mode: A Comprehensive Guide

The Zojirushi water boiler is a popular and reliable appliance that provides users with instant access to hot water. However, over time, mineral deposits and lime scale can build up inside the boiler, affecting its performance and efficiency. To maintain the optimal functioning of your Zojirushi water boiler, it is essential to regularly descale the unit using the built-in descaling mode.

Activating the Descaling Mode

To activate the descaling mode on your Zojirushi water boiler, follow these steps:

  1. Press and Hold the Reboil Button: Locate the reboil button on the control panel of your Zojirushi water boiler. Press and hold this button for approximately 3 seconds until the lights on the LCD display start to flash. This indicates that the water boiler has entered the descaling mode.

  2. Confirm the Descaling Mode: Once the descaling mode is activated, the LCD display will show a rotating square icon, and the water boiler will emit a series of beeps to indicate that the cleaning process has begun.

The Descaling Process

The descaling process on the Zojirushi water boiler typically takes around 1.5 hours to complete. During this time, the water boiler will continue to beep, and the rotating square icon on the LCD display will remain visible, signaling that the cleaning cycle is in progress.

It’s important to note that the duration of the descaling process may vary slightly depending on the level of mineral buildup and the specific model of your Zojirushi water boiler. Some models may have a slightly longer or shorter descaling cycle.

Preparing the Cleaning Solution

For effective descaling, it is recommended to use a citric acid-based cleaner specifically designed for electric water boilers. To prepare the cleaning solution, follow these steps:

  1. Measure the Citric Acid: Refer to the instructions provided by the cleaning solution manufacturer to determine the appropriate amount of citric acid to use. Generally, a ratio of 1 tablespoon of citric acid per 1 cup of warm water is recommended.

  2. Dissolve the Citric Acid: In a separate container, mix the citric acid with the warm water until the powder is completely dissolved.

  3. Pour the Solution into the Boiler: Carefully pour the citric acid solution into the water boiler, ensuring that the water level reaches the maximum fill line.

  4. Activate the Descaling Mode: Once the cleaning solution is in the boiler, press and hold the reboil button for 3 seconds to activate the descaling mode.

Post-Descaling Care

After the descaling process is complete, it is essential to thoroughly clean and rinse the Zojirushi water boiler to ensure that no residual cleaning solution remains. Follow these steps:

  1. Unplug the Power: Before attempting any cleaning or maintenance, unplug the power cord from the electrical outlet to ensure safety.

  2. Detach the Upper Lid: Carefully remove the upper lid of the water boiler, as it may be hot from the descaling process.

  3. Pour Out the Water: Drain the water from the boiler by pouring it out through the drain area located at the back of the machine.

  4. Rinse the Boiler: Fill the water boiler with clean water and let it boil to rinse out any remaining cleaning solution. Dispose of the rinsed water.

  5. Clean the Exterior: Wipe down the exterior of the Zojirushi water boiler with a clean, damp cloth to maintain its appearance and cleanliness.
