is smaller, but each dimension

and angle has been recalculated

and engineered to make a smaller

cyclone as efficient as a big cyclone.

Electrical safety testing

Ensure that at all times during the repair and testing of products

that customers, children, pets and you are not exposed to any

Live electrical supply.

Insulation test

The following tests must be performed prior to

and upon completion of all repairs to Dyson

floorcare products and before any functional

checks.

You must ensure that a full visual inspection of

the product is completed prior to repair.

Test results

An insulation test reading of >2 MW

is acceptable.

A reading of below 2 MWis not considered

safe and will require replacement of the

chassis and motor assembly.

The Seaward Primetest 200 (or equivalent)

should be used to test the electrical

insulation of a Class 11 appliance; it

indicates any electrical leakage.

Insulation test point:

These tests are vital to avoid any possibility

of personal injury to the end user.

If you cannot repair a product with an

insulation test reading of below 2MW

you must inform the customer that the

product is unsafe to use.

Please inform the customer of the

required actions to repair the product

(including the charge structure).

If the product is left un-repaired please

indicate on your paperwork/hand held

device that the product is electrically

unsafe and attach a ‘WARNING:

product electrically unsafe’ sticker in

a visable location on the product.

No power to motor

1. Carry out a resistance test around the entire product (points 1-2) to determine there is a genuine

fault.

2. If there is a fault check the plug, pins and entire length of the powercord for any signs of wear or

damage.

3. Remove the cable rewind assembly from the product (following all safety precautions shown on

pages 08-09), and check for any damage on the outer contacts of the cable wiring retainer

assembly that would result in an open circuit between the wiring retainer and cable rewind

assembly.

4. Carry out a resistance test along the length of the powercord (points 1-3 and 2-4).

5. Remove the actuator housing and check that the wires are attached to the On/Off switch

(points 7 and 8).

6. Check the mechanical actuation of the On/Off switch.

7. Carry out a resistance test across the switch (points 9-10) ensuring the switch is in the On position.

8. Remove the cable wiring retainer assembly from the product (see pages 38 and 39 for instructions)

and check that the Live (point 5) wire from the On/Off switch and Neutral (point 6) wire from the

main body loom are attached to the assembly.

9. Check the cable wiring retainer assembly for any signs of damage that would result in an open

circuit.

10. Carry out a resistance test along the length of the live wire that connects the cable wiring assembly

to the On/Off switch (points 5-7).

11. If all of the above checks do not rectify the fault, replace the Main chassis and motor assembly.

Electrical fault diagnosis

Service manual

General notes

Disconnect the machine from the electrical outlet at

all times during repair and test. Failure to do so could

result in electric shock or personal injury.

Some female terminal clips used in DC26 contain a locking

mechanism. The release pip will need to be activated before

separation from the male terminal can occur.

Ensure that safety goggles are worn where this symbol

is shown.

Cable rewind - removal

Recommended tools to repair DC26:

Torx T-8, T-10, T-15 screwdrivers

Large flat bladed screwdriver

Thin flat bladed screwdriver

Long/needle nosed pliers

01 Remove the cyclone and bin

assembly from the product.

Wire colours may vary between territories.

Service manual

08 Remove the cover.

09 Important: ensure the entire

length of the cable is wound onto

the cable rewind assembly.

Prise the cable protector off the

side of the chassis.

10 Important: press the cable

rewind actuator and allow the

cable rewind assembly to turn

through two revolutions clockwise

to remove any remaining tension

in the cable spring assembly.

Failure to do this could result in

injury when removing the spring

assembly.
