Product overview

Features and benefits..............................................................................................01

This manual is written specifically for Dyson trained engineers and covers the full TP04 and

DP04 range. The service instructions assume that the engineer has the approved tools and

test equipment with them.

Product overview

Features and benefits

Sealed filtration - removes gases and particles

The fully - sealed filter system combines an activated carbon filter to remove

gases, and a Glass HEPA filter that captures 99.97% of microscopic allergens

and pollutants as small as 0.3 microns.

Draft-free diffused mode

New side vent to diffuse purified air,

creating circulation with no draft.

Forward airflow mode

Purifies and cools you.

Backward airflow mode

Purifies without cooling you.

Product overview

Features and benefits

Intelligent sensors detect

pollutants

Particulate, nitrogen dioxide,

and humidity and temperature

sensors continually monitor air

quality in the room. A unique

algorithm processes the input

and activates the machine, to

capture pollutants and project

clean air.

Wider room coverage with 350˚

oscillation

Maximise personal comfort by

customising the oscillation range up

to 350˚ through the App or choose

from 4 standard oscillation settings

from 45˚ to 350˚.

LCD display reports in

real-time.

Dyson Link app

Intelligent purification. Responds and

reports to your Dyson Link app.

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

that customers, pets, children 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 considered

unsafe and further investigation,

rectification and testing must be completed

before the product is used. The following

components must be visually inspected.

• Dust sensor loom and AMP assembly

loom.

The socket and see PDIT 360

(or equivalent) should be used to test

the electrical insulation of a Class 11

appliance; it indicates any electrical

leakage.

Insulation test points:

Test directly onto the four T-10 screws in the

Main body.

Note: the filters will need to be removed to

gain access to the screws.

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 2MWyou

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 visible location on the product.

AQ displays during calibration

When the product is new, the AQ sensors begin calibrating. This 1 hour process will affect

the VOC & NO2readings for the entire 1 hour duration. During this period the product will

show PM2.5/PM10 data after a few seconds of turning on. The following screens will be

displayed.

After the initial one hour calibration, it will take up to 20 minutes to calibrate the VOC and

NO2sensors each time a product has been switched off at the wall or unplugged.

During this period the following screens will be displayed.

After each calibration period the screens will now show readings as below.

Prior to carrying out any repairs that are associated to fauly air quality readings, it is

important to determine whether the product has a genuine fault or is simply calibrating.

Technical infomation

Accessing the diagnostic menu

Diagnostic menu

Built into DP04 and TP04’s software there is an engineers diagnostic menu designed to

enable the repair agent a quick diagnosis of the machines failure.

The menu is accessed by pressing a sequence of buttons via a standard remote control.

Once you have finished accssing the engineering menu, press any button on the remote

except the ‘i’ button to exit the diagnostic menu.

If the engineering screen does not appear press any button to reset and start again.

Repeat all steps ensuring the flow button is pressed between 11 and 13 seconds detailed in

step 3.

AUTO AUTO

AUTO

Switch

machine on. Press night mode

button once.

Hold down flow

button for 11 to

13 seconds.

Immediately press

the oscillation

button once.

Press i button three times to

show fault code screen

(the screen above is an

example).

will appear.

Technical infomation

Diagnostic table

Further information to the above table, the LCD display may show the screens below to

help you diagnose the products fault.

These screens are displayed without having to go into the engineering screen.

Faults codes will be displayed as per the following format: 00X-0X-0X-X.

In most cases it is only necessary to recognise the first three digits to determine the fault.

5. Wrong Power Supply Unit (PSU) inserted/PSU fault, advise to use the Dyson PSU that

came with the machine.

6. Fault. Shown permanently if fatal fault. Shown temporarily if limited

functionality fault. Will be necessary to access diagnostic menu to determine fault.

1. 2. 3. 4. 5. 6.

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.

Recommended tools to repair DP04 and TP04:

Torx T-15 screwdriver (magnetic if possible)

Torx T-10 screwdriver (magnetic if possible)

Torx T-8 screwdriver (magnetic if possible)

Thin flat bladed screwdriver

Long nosed pliers

Wire colours may vary between territories.

All screws used in DP04 and TP04 are Torx unless otherwise stated.

Where this symbol is shown ensure ESD

(Electro Static Discharge) protection is used.

Repair notes

General information

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

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

Live electrical supply.

Some female terminal clips used in DP04 and TP04 contain a

locking mechanism. The release pip will need to be activated

before separation from the male terminal can occur.

Important: this product contains a WiFi PCB that stores critical data.

If a WiFi PCB requires replacement the data will require reinstalling following the repair.

The necessary equipment is not currently available, therefore any machines requiring a WiFi

PCB replacement cannot be repaired until further notice.

A further issue of this manual will be released providing full instructions of the procedure

when the equipment becomes available.

It is a mandatory requirement that when handling any

product during any repair or refurbishment process that

the following equipment is worn:

• FPP3 particle filter Face mask

• Safety gloves

• Safety glasses

• Safety shoes
