Your Dyson DC59 keeps cutting out primarily as a safety mechanism to prevent overheating or damage, often triggered by blockages, filter issues, or problems with the battery or brush bar.
Dyson vacuums, like the DC59, are designed to automatically shut off if they detect an issue that could harm the motor or internal components. This cutting out is usually a signal that something is impeding airflow or the vacuum's normal operation.
Common Reasons for Your Dyson DC59 Cutting Out
Based on common issues with cordless Dyson models and the provided reference, here are the main culprits:
1. Air Blockages & Tangled Hair
This is a very common cause and is directly supported by the reference. If your Dyson DC59 is making a high pitched noise or is cutting out, it's crucial to check for blockages.
- How it happens: Debris, dust, hair, or even larger items can get stuck in the various parts of the vacuum, restricting airflow. This forces the motor to work harder, leading to overheating and the protective shutdown.
- Where to check:
- Dirt Bin: As the reference states, make sure the dirt bin is empty.
- Top Part of the Bin: The reference specifically mentions checking for blockages at the top part of the bin. This area, often near the cyclone technology, is prone to clogging with fine dust and hair.
- Wand and Head: Check the main wand tube and the cleaner head intake for obstructions.
- Brush Bar: Tangled hair or string wrapped around the brush bar can cause it to seize or slow down significantly, triggering a shutdown. The reference also mentions checking for tangled hair.
Action: Turn off and unplug the vacuum. Carefully check the dirt bin (empty and check the top section), the wand, and the cleaner head (especially the brush bar area) for anything stuck. Remove any blockages using a coin, scissors, or a stiff brush.
2. Clogged Filters
A dirty or improperly fitted filter is another frequent cause of cutting out.
- How it happens: Dyson DC59 models typically have a washable post-motor filter. If this filter is clogged with fine dust, it severely restricts airflow through the motor, causing it to overheat and cut out.
- Where to check: Locate the washable filter (often at the back of the motor).
Action: Remove the filter and wash it under cold water until the water runs clear. Ensure it is completely dry (allow at least 24-48 hours of air drying) before putting it back in the vacuum. A damp filter can damage the motor.
3. Battery Issues
The cordless nature means battery health and charge level are critical.
- How it happens: A low charge level or an aging battery that can no longer hold a sufficient charge can cause the vacuum to run for only a short time or pulse before cutting out.
- Action: Ensure the battery is fully charged according to the manufacturer's instructions. If the problem persists even with a full charge, the battery may need replacing.
4. Brush Bar Issues
Problems specifically with the cleaner head's brush bar can cause shutdowns.
- How it happens: Besides tangles (mentioned under blockages), the brush bar motor itself might have an issue, or there could be a blockage in the airway leading to the brush bar head.
- Action: Clean the brush bar thoroughly, removing all tangled hair and debris. Ensure it spins freely by hand (with the vacuum off). Check the connection between the head and the wand.
Summary of Potential Causes & Checks
Here’s a quick guide to troubleshooting:
| Potential Cause | What to Check | Action |
|---|---|---|
| Air Blockage/Tangles | Dirt bin (empty & top section), Wand, Cleaner head, Brush bar | Remove all debris and tangled hair/string. |
| Clogged/Wet Filter | Post-motor filter (usually at the back) | Wash thoroughly (cold water), let air dry completely (24-48 hrs). |
| Low Battery/Battery Fault | Battery charge level, Age of battery | Fully charge battery. Consider battery replacement if issue persists. |
| Brush Bar Problem | Brush bar tangles, Brush bar spinning freely, Airway to brush head | Clean brush bar, check for obstructions in the head, ensure free movement. |
By systematically checking these areas, especially clearing any blockages in the dirt bin and airway as highlighted by the reference, you can often resolve the issue of your Dyson DC59 cutting out and restore its powerful suction.
