Dyson cordless vacuums are known for their powerful suction and convenience, but users may encounter frustrating issues like the device cutting out unexpectedly. Based on reports from various Dyson community forums, there are several common reasons why a Dyson vacuum might stop working intermittently, ranging from blockages and dirty filters to battery problems and software glitches.

Reason#1: Battery Protection Circuit Issues

Battery protection circuit issues can significantly impact the performance of Dyson cordless vacuums, often causing them to cut out unexpectedly. These circuits are designed to safeguard the battery but can sometimes be overly sensitive or malfunction. Here are key points about battery protection circuit issues in Dyson vacuums:

The battery protection circuit monitors voltage and can shut down the motor if it detects potential problems, even when the battery still has usable charge.
1
2
As batteries age, their internal resistance increases, leading to slower voltage recovery after motor startup. This can trigger false alarms in the protection circuit.
2
The simplistic monitoring approach of the protection circuit may cause premature battery replacements, as it doesn't account for normal battery aging.
2
Some users have reported success in resolving battery issues by manually recharging the cells and attempting to reset the Battery Management System (BMS).
3
In some cases, the BMS may enter a low-voltage cutoff mode that persists even after recharging, requiring additional troubleshooting or potential replacement.
3
Dyson's battery warranty typically lasts for 2 years, but issues can arise outside this period, leading to frustration for users.
4

These protection circuit issues highlight the complexity of battery management in cordless vacuums and the potential for design improvements to better accommodate normal battery aging processes.

Reason #2: Air Blockages and Dirty Filters

Dyson vacuum cleaners are designed to detect and alert users to airway obstructions and filter issues that can impact performance. Here are the key points to understand about air blockages and dirty filters in Dyson vacuums:

The machine will change noise pitch and may stop vacuuming when an airway obstruction is detected.
1
A blockage light or LCD screen alert will indicate an "Airway obstructed" issue.
1
2
Common blockage locations include the cleaner head/brush bar, tracks/base plate, and cyclone inlet.
1
To check for blockages, visually inspect these areas with the machine switched off and stationary.
1
Dirty filters can also trigger blockage alerts and reduce suction power.
1
Filters should be washed regularly, at least once a month, to maintain optimal performance.
1
2
If blockage alerts persist after cleaning, check the vacuum's wand and bin inlet for debris.
2
Running the vacuum in boost mode for a few minutes may help clear minor blockages.
3
Ensure the filter is properly sealed after cleaning, as misalignment can cause faulty readings.
3
If issues continue, consult the user manual, Dyson's online support, or official YouTube channel for detailed troubleshooting steps.

Reason #3: Faulty Charging Components

Faulty charging components can be a significant cause of Dyson vacuums cutting out or failing to charge properly. Issues may arise from various parts of the charging system, including the charger itself, the battery, or the internal components of the vacuum. Users have reported problems such as batteries not holding a charge, chargers failing to deliver power, or the vacuum's internal circuitry preventing proper charging

. In some cases, the issue may lie within the handle component, which contains the electrical and power components for charging and operation

. To diagnose charging problems, users can try charging the battery separately from the vacuum. If the battery charges when removed but not when connected to the vacuum, it may indicate a fault in the handle or main body

. Additionally, the Battery Management System (BMS) can sometimes become overzealous and prevent an otherwise functional battery pack from working, necessitating a reset or replacement of the BMS itself

Reason #4: Motor or Brush Issues

Mechanical issues can significantly impact the performance of Dyson vacuums, causing them to cut out unexpectedly. These problems often stem from wear and tear on moving parts or debris accumulation in critical areas. Here are the key points to consider regarding mechanical issues in Dyson vacuums:

Brush bar problems: Hair and debris can wrap around the brush bar, causing it to seize up and trigger the vacuum's safety cutoff.
1
Bearing issues: Worn-out bearings in the brush bar or motor can cause excessive friction and overheating, leading to shutdowns.
1
Motor malfunctions: The main motor or the smaller motor in the power head can fail, causing the vacuum to cut out after a few seconds of operation.
1
Lubrication needs: Lack of proper lubrication on bearings and moving parts can increase friction and cause overheating.
1
Cleaning importance: Regular cleaning of the power head, including removal of hair and debris, can prevent many mechanical issues.
1
Proper maintenance: Oiling bearings with appropriate lubricants (e.g., lanolin oil) can extend the life of mechanical components.
1
False blockage reports: Sometimes, mechanical issues can trigger false blockage alerts, leading users to focus on the wrong problem.
2

By addressing these mechanical issues through regular cleaning, proper lubrication, and timely repairs, users can often resolve cutting out problems without needing to replace the entire unit or its battery.

Reason #5: Software and Firmware Glitches

Software glitches and electronic malfunctions can cause Dyson vacuums to unexpectedly cut out during operation. These issues may stem from the vacuum's internal circuitry or programming errors. Here's a summary of key points related to software and electronic problems in Dyson vacuums:

Issue	Description
Software bugs	Firmware glitches can cause erratic behavior, including unexpected shutdowns 1
Circuit board faults	Damaged or faulty circuit boards may lead to intermittent power issues 2
Sensor malfunctions	Faulty sensors can trigger false blockage or overheating alerts, causing shutdowns 3
Power management errors	Incorrect power distribution can cause the vacuum to cut out prematurely 4
LCD screen issues	Display malfunctions may provide inaccurate information about the vacuum's status 5

To address these problems, users may need to perform a system reset, update the vacuum's firmware if available, or seek professional repair for more complex electronic issues. In some cases, replacement of internal components may be necessary to resolve persistent software or electronic malfunctions.
