If your Morphy Richards kettle makes humming, rumbling, crackling, popping or bubbling sounds while heating water, this is usually normal and does not automatically indicate a fault.
All kettles make some noise as water heats and boils. However, excessive limescale build-up can make these sounds louder or more noticeable.
Why Does My Kettle Make Noise When Boiling?
Noise is a normal part of the boiling process.
As water heats, small bubbles form and collapse against the kettle's heating surface. This creates vibration and sounds such as:
- Humming or buzzing: A continuous sound as the water heats.
- Rumbling or roaring: A louder sound as bubbles form and the water approaches boiling point.
- Crackling or popping: Small bubbles forming and collapsing during heating.
- Bubbling: Water reaching boiling point.
The type and volume of noise can vary between kettle models, depending on their construction, heating element and the amount of water being heated.
Normal boiling noises do not mean the kettle is faulty.
Why Is My New Kettle Noisy?
A brand-new Morphy Richards kettle may make noticeable humming, rumbling, crackling or popping sounds during its first few uses.
This is usually caused by the normal heating and boiling process. Different kettle designs can also sound louder than appliances you have previously owned.
A new kettle does not need to be silent to operate correctly.
Before first use, follow the initial cleaning instructions supplied with your kettle, including boiling and discarding water where instructed.
If the kettle heats water normally, switches off automatically and shows no other signs of a problem, boiling noise alone is generally not a cause for concern.
Why Does My Kettle Crackle, Pop or Sound Louder Than Before?
Limescale build-up is a common reason why a kettle may become louder over time.
Limescale is a natural mineral deposit that forms when water is heated. It can accumulate on the kettle's heating surface and affect how heat transfers into the water.
This can make boiling sounds more noticeable, including crackling, popping and rumbling.
Limescale:
- Is caused by minerals naturally present in the water supply.
- Can develop in both hard-water and soft-water areas.
- Generally builds up more quickly in hard-water areas.
- Is a maintenance issue and does not automatically indicate a manufacturing fault.
If your kettle has gradually become noisier, thorough descaling is the recommended first troubleshooting step, provided there are no signs of an electrical or other safety issue.
How Can I Reduce the Noise My Kettle Makes?
If your kettle is operating normally but has become louder, follow these steps:
- Switch off and unplug the kettle, allowing it to cool completely.
- Check for limescale deposits inside the kettle, particularly around the heating surface.
- Descale thoroughly using a proprietary kettle descaling product suitable for your appliance.
- Follow the descaling product's instructions, including the recommended quantity and treatment time.
- Rinse the kettle thoroughly as directed and ensure the electrical connections are completely dry before use.
Morphy Richards recommends descaling approximately once a month as a general guide, depending on usage and water hardness. More frequent descaling may be necessary where mineral deposits develop quickly.
Always fill the kettle between its MIN and MAX markings and avoid leaving water standing unnecessarily between uses.
Descaling may reduce noise caused by mineral deposits, but it will not eliminate the normal sounds of heating and boiling water.
Does a Noisy Kettle Mean It's Faulty?
Not necessarily.
Humming, bubbling, rumbling and occasional crackling during heating are generally normal, including in new kettles.
If the kettle boils water correctly and switches off automatically, noise alone does not establish a manufacturing fault.
However, stop using the kettle and contact Customer Support if you notice:
- Loud, unusual mechanical noises that are clearly different from normal boiling sounds.
- A burning smell, smoke, sparking or other signs of an electrical problem.
- Water leaking from the appliance.
- The kettle failing to switch off automatically.
Do not continue operating an appliance showing any of these symptoms.
Is It Normal for My Kettle to Make Noise?
Yes. Humming, rumbling, bubbling, crackling and popping are normal sounds associated with heating and boiling water.
The type and volume of noise can vary between kettle models, including brand-new appliances.
Limescale build-up can make these sounds more noticeable, so regular descaling is recommended to maintain performance.
If your kettle heats water correctly and switches off automatically, these noises are generally nothing to be concerned about and no further action is necessary.
