If your Morphy Richards kettle makes crackling, popping, or unusual sounds during boiling, this is usually normal and nothing to worry about.
In many cases, limescale or mineral deposits can make these sounds more noticeable, especially in areas with hard water.
This guide explains why your kettle may make these noises and how to keep it performing safely.
Why your kettle crackles or makes unusual sounds
Kettles naturally make sounds as water heats and boils:
Bubbles form and collapse as water heats, creating vibration and noise
Mineral deposits (limescale) can cause water to boil unevenly, increasing crackling or popping sounds
Frequency of use and water hardness can make these sounds more noticeable
⚠️ Important: Noise alone is usually not a sign of a fault. Always ensure your kettle is regularly descaled according to the user manual to maintain performance.
What is limescale and how it affects noise
Limescale is a white, chalky deposit made of minerals like calcium and magnesium found in tap water.
It forms when water is heated
It can coat the concealed heating element
Over time, it may make boiling water sound louder or crackle
Regular care helps prevent excessive build-up and reduces unusual noises.
How to care for your kettle
As outlined in the Morphy Richards user manual:
Descale regularly – we recommend descaling your kettle every month, depending on water hardness and usage
Use a proprietary descaling product suitable for stainless steel, glass, or plastic
Follow the product instructions carefully
Ensure electrical connections are completely dry before using the kettle
⚠️ Regular descaling helps reduce noise, maintain performance, and protect your kettle.
How to reduce noise
Empty the kettle after use instead of leaving water standing
Avoid overfilling beyond the maximum line
Descale regularly, especially in hard water areas
These simple steps help keep your kettle running quietly and efficiently.
