Introduction
You are holding the service manual for the TD25 generation of tumble dryer.
There are two types of tumble dryer in the TD25 series: TD25.1 and TD25.3. The following page presents
the different versions, to help you identify the machine types. The variants are named differently from mar-
ket to market. The type designation is the most important factor for identifying the machine type. The type
designation can be found on the machine plate, which is located inside the machine’s door.
It should be easy to service a tumble dryer. It is important that you, as a service technician, are given the
conditions to be able to carry out work in an efficient and satisfactory way. Our hope is that this service
manual is a useful tool for your daily work.

Programme
When using tumble dryer TD25 it is possible to choose between four different programmes that automati-
cally sense how damp the washing is. The machine dries to different levels depending on which of the four
programmes has been selected on the front panel. The machine only has one automatic programme that
runs for different lengths of time (and therefore dries to different levels) depending on which of the four pro-
grammes has been selected on the front panel. The automatic programme runs for a maximum of 3 hours.
The machine has a Timer programme that runs for the time that is set (20 minutes – 2 hours), regardless of
whether the washing is dry or not.
The machine has an Airing programme that blows cold air for the time that is set (5 minutes – 2 hours).
Indication of programme sequence
During the programme, the current programme sequence is indicated by a fixed light in the LEDs around
the start/stop button (see the image).
The cycle time is calculated during the start sequence.
Note!
If the door is opened whilst a programme is in operation, the programme will be interrupted and return to
the start position.

Options and settings
Options
2h
Means that the drum will rotate 3 seconds per minute for 2 hours once the drying
programme has finished. The option prevents the fabrics from remaining in the
same position and becoming creased, which is good if you are unable to remove
them immediately after tumble-drying has finished.
If the Buzzer is also activated
a signal will sound each time the drum rotates, as a reminder that the drying pro-
gramme has finished.
5h
Delays the start of the machine by 5 hours.
Activated by pressing the Time-delayed start button and then the start/stop but-
ton.
The number 5 in the display indicates that Time-delayed start has been activated.
The number of hours to start is displayed with a countdown from 5 to 1.
Deactivated by pressing the start/stop button for 3 seconds until the red field next to
Time-delayed start goes out.
This means that a buzzer will sound for 3 seconds when the drying programme
finishes.
Reduces cooling to 3 minutes.
Cannot be used in the Airing programme.
(In ”normal cases” when Short cooling is deselected, the machine cools for 15
minutes. )
Settings
Possible to set to a high or low temperature.
High temperature Low temperature
Airing dryer: 57°C 43°C
Condenser dryer: 73°C 50°C
Temperature setting cannot be carried out in the airing programme.

Troubleshooting
Fault indications
The following faults are indicated by a flashing red light in the start/stop button LEDs and as a trouble code
on the display (display not available on all machine versions).
Fault indication Cause Action
Display LEDs
(flashing)
Meaning
Overfilling
The machine stops.
(applies to condenser
dryers)
The condensation water tank
is full.
Check if the customer has:
• Emptied the tank and
restarted the machine
Condensing waterpump or
hoses blocked.
• Clean hoses and check
voltage and resistance in
the drain pump.
Float/float switch is defective. • Check that the float has
not got “stuck” and check
the function of the micro-
switch.
The control unit is faulty (the
pump does not start).
• Replace control unit.
Maximum permitted pro-
gramme time
The machine stops after 3
hours.
The washing has been spun
at too low a speed, i.e. less
than 800 rpm.
Check if the customer has:
• Tried spinning at a higher
speed
The control unit did not have
chance to reset, but added
the time to the next drying
cycle.
Check if the customer has:
• Has the machine switched
off for 30 minutes before
restarting
High ambient temperature
combined with low element
output and low drying tempe-
rature leads to condensation
formation.
Check if the customer has:
• Attempted to select an-
other programme
• Good ventilation in the
room
Poor condensation due to
blocked external air
• Ensure that the external air
has free passage.
Defective thermistor. • Replace the thermistor.
Defective control unit • Replace control unit.
(no indication in
LEDs)
Thermistor fault
The machine stops.
The front thermistor is de-
fective or the control is not in
contact with it.
• Replace the thermistor.
After carrying out corrective actions as above, reset the fault indications by switching off the machine using
the main power switch.
