If your Morphy Richards Soup Maker is making an unusual noise during cooking or blending, it doesn't necessarily mean there's a fault.
Soup makers combine heating and blending functions, so it's normal to hear different sounds throughout a cooking programme. However, certain noises may indicate an ingredient-related issue, an obstruction or a problem that requires further investigation.
This guide explains which sounds are generally normal, what might cause unusual noises and when to contact us for assistance.
1. What Noises Are Normal?
Depending on your soup maker model and the programme selected, you may hear several sounds during operation.
Whirring or blending noises
The motor and blades make a whirring sound when blending ingredients. This may become louder or change in pitch depending on the quantity and consistency of the contents.
Some programmes blend intermittently, so the motor may start and stop at different stages of cooking.
Gentle bubbling or simmering
As the soup heats, you may hear bubbling, simmering or other cooking sounds. These are generally expected during heated programmes.
Occasional clicking
Some models may produce occasional clicking sounds as internal heating controls operate.
Changes in motor sound
The sound of the motor may vary as ingredients soften and the consistency changes during blending.
These sounds are not necessarily signs of a fault, provided the appliance is operating normally and there are no other unusual symptoms.
2. Loud Rattling or Excessive Vibration
Why might this happen?
Rattling or vibration may be related to:
- Large or hard ingredients moving around the jug.
- Ingredients being unevenly distributed.
- The appliance standing on an uneven or unstable surface.
- The lid not being correctly fitted.
- A possible issue with the blade or motor assembly.
What should I check?
- Switch off and unplug the appliance.
- Allow the soup maker and its contents to cool before opening the lid.
- Check that the appliance is positioned on a flat, stable surface.
- Ensure the lid is correctly fitted and that no food residue is preventing it from sitting securely.
- Review the size and quantity of ingredients against your model's instructions.
For future recipes, cut vegetables into appropriately sized pieces and avoid exceeding the recommended filling levels.
If the appliance has developed persistent or excessive vibration, particularly if it appears unstable or moves across the worktop, stop using it and contact Customer Support.
3. Grinding, Scraping or Metallic Noises
Grinding, scraping or metallic noises are not sounds you should ignore.
They may indicate:
- An obstruction around the blades.
- A hard object or unsuitable ingredient inside the jug.
- Damage to the blade assembly.
- A possible mechanical issue involving the motor or blade mechanism.
What should I do?
- Stop using the appliance immediately.
- Switch off and unplug it.
- Allow the appliance and contents to cool completely.
- Empty the jug carefully and visually inspect the accessible blade area for food residue or foreign objects.
- Clean the blade area using the method recommended for your model.
Important: The blades are extremely sharp. Never place your fingers into the blade assembly, attempt to turn the blades by hand or use tools to force them free.
Do not dismantle the motor or blade assembly.
If the noise cannot be explained by an obvious removable obstruction, or there is any visible damage, do not restart the appliance. Contact Customer Support for further assistance.
4. Humming or Straining Without Blending
If your soup maker produces a humming or straining noise but the ingredients aren't being blended, the motor may be attempting to operate without the blades moving correctly.
Possible causes include:
- Ingredients obstructing the blades.
- Too many ingredients or insufficient liquid.
- Large or unusually hard ingredients.
- A possible mechanical or motor-related fault.
What should I do?
Stop using the appliance and unplug it.
Once completely cool, review the ingredient quantities and visually inspect the accessible blade area for obstructions, following the safe cleaning instructions for your model.
If the motor continues to hum or strain without blending, do not attempt further operation.

If the blades remain stationary or the motor appears to be struggling, contact Customer Support.
5. Loud Blending Noises
Blending can be noticeably louder than heating, particularly when the motor first starts or when processing thicker ingredients.
The sound may also vary depending on:
- The type and quantity of ingredients.
- The consistency of the mixture.
- Whether ingredients are raw, cooked or partially softened.
- The blending programme selected.
However, a sudden change in noise, unusually harsh grinding or excessive vibration should not be dismissed as normal.
If your soup maker has become significantly louder than usual and you cannot identify an ingredient-related explanation, contact Customer Support.
6. Clicking or Other Sounds During Heating
Some clicking sounds may be associated with heating controls operating during the cooking cycle.
You may also hear bubbling or changes in sound as the contents heat.
These sounds are generally less concerning when the appliance continues its programme normally.
However, if clicking is accompanied by:
- The appliance repeatedly switching off.
- A burning smell or smoke.
- Sparks or visible electrical damage.
- Household electrics tripping.
Stop using the appliance and contact Customer Support.

7. How Can I Reduce Unnecessary Noise?
To help your soup maker operate as intended:
- Use suitable ingredients: Follow your model's guidance on ingredient types and preparation.
- Cut ingredients appropriately: Avoid adding large or unusually hard pieces that may be unsuitable for blending.
- Check filling levels: Keep the contents within the recommended MIN and MAX levels.
- Use enough liquid: Follow the recipe and filling instructions for your model.
- Position the appliance correctly: Place it on a flat, stable worktop.
- Fit the lid securely: Make sure the lid and jug rim are clean and unobstructed.
- Keep the blade area clean: Remove food residue using the cleaning method specified for your appliance.
These steps can help reduce noise caused by ingredients, positioning or residue, but they will not resolve a damaged blade or motor component.
8. When Should I Contact Morphy Richards?

- The appliance suddenly becomes significantly louder than normal.
- Unusual noises are accompanied by smoke, sparks, electrical smells or repeated power interruptions.
