Smeg Hob Isn't Turning On - Causes and Solutions

Smeg hobs are found in many UK kitchens and are loved for their quality and variety. They come in a range of shapes and sizes and are available in a range of fuel types including gas and induction.

Yet regardless of which type of hob you have, these appliances can falter occasionally.

If you’re dealing with a Smeg hob that isn’t turning on, it can be extremely frustrating.

Here we will help you troubleshoot the issue and provide actionable solutions.

Hopefully, with the use of this guide, your Smeg hob will be working again in no time.

There are several reasons why your Smeg hob might not be turning on.

From faulty power supplies to dirty appliances, you might be dealing with a simple fix… or there might be faulty internal parts that need replacing.


Cause 1: Your Smeg Hob Is Dirty

One of the main reasons for hobs not turning on is because they are dirty. Many induction hobs and electric stoves have touchscreen control panels.

If there is a layer of grease covering the buttons, the touchscreen recognition will struggle to work effectively.

Take a damp cloth and a cleaning product that can budge tough grease to remove the debris and see if this solves the issue.

Smeg gas hobs can also benefit from being cleaner. Grease can work its way into the burner and insulate the grounding for the spark. This prevents the burner from igniting.

To clean away the grease, remove the burner from the cooktop and boil it in a pan of soapy water for several minutes.

Once finished, leave it to cool, rinse it with clean water, and let it air dry before replacing it.


Cause 2: Your Hob is Locked

Smeg induction and electric hob models with touchscreen controls often have a lock function. This is a safety feature that prevents anyone from accidentally tampering with the heat settings.

If you have accidentally turned on the lock features without realising it, your induction hob won’t turn on.

To fix this issue, you simply need to deactivate the lock. You can do this by following these steps:

  1. Check to see if the lock symbol (L) is showing on your hob, which shows the lock is on
  2. Simultaneously press the + and – buttons on the control panel and a buzzer will sound
  3. Press the + button again and the lock will deactivate and the L symbol will disappear


Cause 3: Your Hob Isn’t Receiving Power

Induction and electric hobs need to be plugged into a power source to function.

Check that the appliance is securely plugged into a functional power socket.

If it isn’t, plugging it back in should be all it needs for your Smeg hob to function again.

There could also be something wrong internally with your Smeg hob that means power isn’t reaching the components it needs to turn on.

This could still be a simple fix such as a broken fuse that needs replacing.

However, keep an eye out for any of the following error codes on the display: Er03, Er20, Er22, Er31, Er47, E/2, E/5, E/6, E/7, E/9, or U400.

These all indicate larger issues that require the help of a qualified engineer.


Cause 4: Something Is Wrong With the Ignition

Unlike induction hobs, gas hobs don’t require electricity. If they aren’t turning on, there is more likely an issue with the ignition.

Cleaning blocked burners helps fix the issue in many cases; however, there is a chance your hob Smeg hob has defective components.

Check the appliance for signs of damage by following these steps:

  1. Remove the defective burner base and look for loose connections or disconnected wires. If there are any loose wires, secure the connections and replace the burner.
  2. Turn the ignition on and look at the colour of the spark. A yellow or orange spark indicates the ignitor needs replacing, whereas a blue spark is healthy. You will need to install a new ignitor to solve the issue.
  3. If this doesn’t work, contact Smeg customer service. The ignition module or ignitor switch probably needs replacing instead, and this is a job for a professional.
