If your Morphy Richards kettle is noisy when boiling, this is usually completely normal.
Kettles naturally make sound as water heats up and begins to boil. However, in some cases, limescale build-up inside the kettle can make these sounds louder or more noticeable.
This guide explains why kettles make noise and how to care for your kettle to keep it performing as expected.
Why your kettle is noisy when boiling
It’s normal for kettles to make noise during operation. This happens because:
Water forms bubbles as it heats, which rise and collapse
These bubbles create vibration and sound inside the kettle
As the water reaches boiling point, the noise may become louder
In many cases, this is simply part of the normal boiling process.
When noise may be more noticeable
If your kettle sounds louder than usual, this is often linked to limescale build-up.
Limescale can:
Form a layer on the concealed heating element
Cause water to heat unevenly
Create additional vibration or crackling sounds during boiling
This is more common in areas with hard water or where the kettle is used frequently.
What is limescale?
Limescale is a white, chalky deposit made up of minerals naturally found in tap water.
It forms when water is heated
It builds up over time inside your kettle
It is more common in hard water areas
Limescale is not a fault, but it can affect performance and change how your kettle sounds.
How to care for your kettle
As outlined in your Morphy Richards user manual, regular care is important:
Descale regularly – we recommend descaling your kettle every month, depending on usage and water hardness
Use a proprietary descaling product suitable for stainless steel, glass or plastic
Follow the descaling product instructions carefully
Ensure all electrical connections are completely dry before using the kettle
⚠️ Important: Regular descaling helps reduce noise and maintain your kettle’s performance over time.
How to reduce kettle noise
Descale regularly, especially in hard water areas
Empty the kettle after use instead of leaving water standing
Avoid overfilling beyond the maximum fill line
With regular care, your kettle should operate more quietly and efficiently.
