If your Miele vacuum cleaner isn’t turning on, you might be feeling frustrated and unsure about what to do.

Don’t worry; you’re not alone!

In this guide, we’ll walk you through some common reasons why your Miele vacuum might not be working and offer simple solutions to get it up and running again.


Fixing Miele Vacuum Not Turning On – 12 Steps

Following are several troubleshooting steps you can follow to resolve the issue, ensuring your vacuum is back in action quickly and efficiently.

Let’s dig into it!

1. Check the Power

Start by checking if the power outlet you’re using is functional. Ensure it’s receiving power by testing it with another device.

It’s important to confirm that the circuit breaker on your home’s electrical panel hasn’t been tripped, as this can result in a loss of power to the outlet.

Check for the Battery:

If you have a cordless vacuum, make sure it has enough battery charge to operate. If the battery is depleted, charge it before attempting to use the vacuum.

2. Check Shutdown Due to Thermal Sensor

If your vacuum powers on but unexpectedly shut off while in operation, it could be due to the activation of a thermal sensor. This typically occurs when the vacuum overheats, often because of blockages or other related issues.

To resolve this, allow the vacuum to cool for approximately three hours to allow the thermal sensor to reset. If it powers on again, promptly switch it off to address any potential clogs that may be causing overheating.

3. Check for Power Switch

Examine the vacuum’s power switch. Ensure it’s functioning correctly and not stuck in the “off” position. If the switch appears to be faulty or isn’t responding, you may need to perform a continuity test using a multimeter to determine if it needs replacement.

4. Inspect Filter and Bag Installation

Ensuring optimal performance for your vacuum depends on having filters and bags correctly installed.

Here’s how to do it

Check that the filter and bag are securely in place within the vacuum. Pay close attention to the housing and confirm there are no gaps or loose fittings that could compromise their effectiveness.

Filters and bags that are not properly seated or have gaps can lead to reduced suction power and decreased cleaning efficiency.

5. Check for Blockages

Ensure there are no blockages in the following components to maintain proper vacuum function:

1. Powerhead:

Examine the powerhead closely, paying attention to the brush and intake areas. Remove any visible obstructions or tangled debris to allow for effective cleaning.

2. Vacuum Hose:

Disconnect the vacuum hose and inspect it thoroughly. Look for any clogs or blockages that might hinder airflow. Clear any obstructions using suitable tools or by gently pushing them out.

3. Miele Filters:

Access the Miele filters, including pre-motor and HEPA filters, as per your vacuum’s manual. Check for accumulated dirt and debris. If filters are dirty or clogged, clean or replace them according to manufacturer guidelines.

This step ensures optimal suction performance and prevents debris from being expelled during vacuuming.

6. Inspect Brush Rotation

The brush is a vital component for efficient cleaning. If your vacuum isn’t performing as expected or not turning on, it’s essential to examine the brush’s functionality.

1. Check Rotation:

Start by observing whether the brush is rotating properly when the vacuum is in operation. Ensure it’s spinning smoothly and without any unusual noises.

2. Safety Features:

Be aware that some vacuum models incorporate safety features that automatically halt the brush’s rotation upon encountering an obstruction.

3. Troubleshoot Obstructions

To address this issue, follow these steps:

  • Turn off and unplug the vacuum for safety.
  • Examine the brush area carefully for any entangled debris, such as hair or threads.
  • Remove any obstructions that may impede the brush’s movement.
  • If necessary, reset the brush according to your vacuum’s instructions.

  • Disassembly (if necessary): If you encounter problems with the cord reel, you may need to disassemble the vacuum to access and inspect it more closely.

8. Replace the Cord Reel (If Needed):

If you find that the cord reel is damaged or not functioning correctly, you should consider a replacement.

However, it’s crucial to emphasize that replacing the cord reel involves intricate steps. It’s advisable to attempt this task only if you have experience or confidence in handling such repairs.

Follow the steps below to replace the cord reel:

  • Initiate the process by disconnecting the vacuum cleaner hose and accessing the bag and exhaust filter.
  • Achieving full removal of the vacuum’s lid by carefully releasing the lid arms from their fixed positions.
  • Progressing by removing the speed control box, accomplished through the unscrewing of a single screw and releasing two clips.
  • After eliminating the speed control box, you can proceed to unscrew the plastic body of the vacuum cleaner from its base, thereby exposing the motor and cord reel.
  • With the cord reel now visible, disconnect any wires linked to it and remove the securing screw.
  • After successfully detaching the cord reel from the vacuum, it should be easily lifted out.
  • Upon the complete removal of the old cord reel, you have the option to install a new one.

Follow the steps below to replace the suction motor:

  • Carefully remove the motor from its housing, taking care not to damage it or the surrounding foam padding.
  • Note the way each wire is connected to the motor before disconnecting them; this information is crucial for reconnecting the new motor correctly.
  • Attach the new motor to the wires, making sure to replicate the previous wiring configuration.
  • Wrap the new motor with foam padding to protect it.
  • Reinstall the motor securely into its housing.
  • Reassemble all other vacuum cleaner components.
  • If the steps are followed correctly, your vacuum should now be functioning normally with the new motor.
