Dyson DC59 Not Picking Up: Fixing Guide

The Dyson DC59 is a powerful cordless vacuum cleaner that normally offers exceptional suction power. However, when it stops picking up debris effectively, it can be frustrating. Fortunately, most pickup issues can be resolved with proper troubleshooting and maintenance. This guide will walk you through the common causes and solutions to get your Dyson DC59 working like new again.

When your Dyson DC59 pushes debris around instead of sucking it up, it’s typically due to one of several issues: blockages in the head or hose, a stuck changeover valve, a worn brush roll, loose connections, or a full dust bin. By systematically checking each component, you can identify and fix the specific problem affecting your vacuum’s performance.

Common Reasons Your Dyson DC59 Isn’t Picking Up

When your Dyson DC59 fails to pick up debris effectively, it typically manifests in one of two ways: complete suction loss or irregular pulsation. With suction loss, you might notice strong suction from the tube but nothing from the cleaning head. The vacuum might simply push small debris along the floor instead of collecting it. With pulsation issues, the vacuum vibrates excessively during operation, indicating internal problems.

The most common causes include:

• Blockages in the cleaning head or hose
• A stuck changeover valve
• A worn or damaged brush roll
• Loose connections between components
• A full dust bin
• Clogged filters
• Motor issues
• Incorrect cleaner head height setting

Each of these problems requires a specific approach to diagnosis and repair, which we’ll cover in detail below.

Step-by-Step Troubleshooting Process

Quick Initial Checks

Before diving into more complex solutions, start with these simple checks:

1. Empty the dust bin completely – Even if it’s not full, debris can block the cyclone inlet
2. Inspect the hose visually – Look for obvious blockages or damage
3. Check and clean the filters – A clogged filter dramatically reduces suction power

These basic maintenance steps often resolve minor suction issues. If your vacuum still isn’t picking up properly, proceed to more detailed diagnostics.

Diagnosing Blockages in the Cleaning Head

The cleaning head is often the culprit when your Dyson DC59 stops picking up effectively. Here’s how to check it:

1. Detach the cleaning head from the vacuum
2. Recline the machine and test the suction directly from the connection point
3. If suction is strong at this point but weak when the head is attached, the issue lies within the head itself

Look for hair, string, or debris wrapped around the brush roll. Remove any obstructions and ensure the brush can rotate freely. If the brush roll is damaged or excessively worn, it may need replacement.

Examining the Critical Changeover Valve

The changeover valve is a vital component that redirects suction between the hose and cleaning head. When stuck, it can cause significant pickup problems:

1. Access the changeover valve by removing the ball cover and filter
2. Use needle-nose pliers to inspect for obstructions like pens or small pieces of tubing
3. Check if the valve moves freely on its spring
4. Manually flip the valve to ensure proper movement
5. Remove any debris that might prevent the valve from switching correctly

A properly functioning changeover valve should move smoothly without catching on anything. If it remains stuck after cleaning, internal damage might require professional repair.

Inspecting Hose Connections

Poor connections between hose components can cause significant suction loss:

1. Check the small suction hose for cracks or damage
2. Ensure the hose is securely connected at both ends
3. Locate the tube with a red cap at the back of the machine and verify it’s properly attached
4. If the tube has come out completely, reconnect it at the bottom
5. Examine the tube for blockages and rips
6. Look for the hose clip through the rectangular hole at the bottom of the machine

If the clip isn’t visible, you may need to remove and reattach the hose correctly. Damaged hoses should be repaired or replaced to restore proper suction.

Brush Roll Troubleshooting

When the brush roll doesn’t spin properly, your vacuum’s pickup ability suffers dramatically:

Cleaning and Inspecting the Brush Roll

1. Remove the brush roll by detaching the sole plate (turn the plastic screw a quarter turn counterclockwise)
2. Clean the brush thoroughly, removing all hair and debris
3. Check for signs of wear or damage that might require replacement
4. Ensure the brush spins freely before reinstallation

Deep Cleaning the Brush Bar Mechanism

For persistent issues with the brush not spinning:

1. Remove the end cap and slide the brush bar out
2. Use a Torx T10 screwdriver to remove the screws securing the internal plate
3. Pry out the plate to expose accumulated dirt and hair
4. Clean the motor and bearing thoroughly
5. Apply lubricant (like WD-40) to ensure smooth rotation
6. Reassemble carefully, ensuring correct motor wire connections

Addressing Electrical Connection Problems

Sometimes the brush head stops rotating despite the vacuum maintaining suction. This often indicates electrical connection issues:

1. Disassemble the vacuum’s dustbin by pressing and twisting its release mechanism
2. Locate the electrical connection points near the canister’s base
3. Clean these connections using dry Q-tips, followed by alcohol-soaked Q-tips
4. Remove all debris to restore proper conductivity
5. Reassemble the canister and reconnect the motorhead

After thorough cleaning of the connection points, the motorhead should resume normal rotation.

Filter Maintenance for Optimal Performance

Proper filter maintenance is crucial for preventing motor pulsing and reduced suction:

Front Filter Cleaning

1. Access the front filter by removing the retaining screw under the filter housing
2. Clean the filter thoroughly with water
3. Allow it to dry completely before reinstallation (usually 24 hours)

Rear Filter Maintenance

1. Remove the battery retaining screw and disengage the rear panel
2. Clean the filter and surrounding area with water
3. Use a dry paintbrush to remove debris from hard-to-reach areas
4. Ensure thorough drying before reassembly

Additional Fan and Contact Checks

1. Remove the dust bin by double-clicking it open
2. Depress the white tab inside the bin housing
3. Press the Dyson’s sides gently to release the filter assembly
4. Inspect fan blades for debris
5. Clean electrical contacts to ensure proper power delivery to the brush bar

Advanced Diagnostic Techniques

Motor Evaluation

If basic troubleshooting doesn’t resolve the issue, check the motor:

1. Listen for unusual noises like grinding or whining during operation
2. Feel the motor housing for excessive heat
3. Check for consistent performance or intermittent power issues

Motor problems often require professional repair, but identifying them can save time and frustration.

Cleaner Head Height Adjustment

An incorrectly adjusted cleaner head can push debris instead of collecting it:

1. Check if your model has height adjustment settings
2. For hard floors, use a lower setting to create proper suction
3. Consider using a Dyson Soft roller cleaner head, which is optimized for hard floors

If you primarily have hard floors, upgrading to a soft roller cleaner head can improve pickup performance.
