If you can see white or chalky deposits inside your Morphy Richards kettle, this is completely normal and not a fault.
These deposits are known as limescale, a natural build-up that occurs when water is heated. While it is common, regular care is important to keep your kettle performing at its best.
This guide explains what limescale is, why it forms, and how to manage it safely.
What is limescale?
Limescale is a natural mineral deposit made up of calcium and magnesium, which are found in tap water.
It appears as a white, chalky residue inside your kettle
It forms when water is heated and minerals are left behind
It can build up over time, particularly on the heating element and inner surfaces
Limescale is harmless but can affect how your kettle performs if it builds up.
Why does limescale form in kettles?
Limescale forms as part of the normal boiling process:
Tap water contains dissolved minerals
When water is heated, these minerals separate and settle
Over time, they form visible deposits inside the kettle
This happens more quickly in hard water areas, but all kettles will develop some limescale with regular use.
How limescale can affect your kettle
If limescale builds up, you may notice:
Increased noise during boiling
The kettle switching off before boiling
The kettle continuing to boil for longer than expected
Regular care helps prevent these issues and keeps your kettle working efficiently.
How to care for your kettle
As outlined in your Morphy Richards user manual, regular descaling 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: Excessive limescale can affect performance and may lead to operational issues. Regular descaling helps maintain your kettle and supports long-term use.
How to reduce limescale build-up
Empty the kettle after use instead of leaving water standing
Avoid overfilling beyond the maximum fill line
Descale more frequently if you live in a hard water area
With regular care, limescale can be managed easily and your kettle will continue to perform as expected.
