Introduction
You are holding the service manual for TD70 tumble dryers. It should be easy to service a tumble
dryer. It is important that you, as a service technician, are provided the necessary conditions to
work in an efficient and satisfactory manner. Our hope is that this Service & Training Guide is a
useful tool for your daily work.

Troubleshooting strategy
Troubleshooting is an important part of the service callout, and as such we have drawn up a
troubleshooting strategy that describes, in broad terms and step by step, what you need to do to find
and diagnose faults arising in our machines.
• Ask the customer to describe the problem.
• Check whether the customer’s description matches the reported fault.
• Check that the machine is correctly installed:
- Electrical connection
- Drainage
- Water connection
- Machine correctly levelled
Fault
found?
No
Yes
Incorrect installation or external factors that affect performance and functionality (for
example, water pressure, electrical supply, drainage).
The machine operates normally. No deviations can be found. The customer probably
needs to be informed about proper use of the machine. If necessary, also inform the
customer about the warranty conditions and the fact that the customer will be charged
for the service call.
Open the service menu:
1. Check the settings
2. Run a test cycle
3. Note any fault codes
If the above actions do not uncover the fault:
• Conduct general troubleshooting. Use the documentation available at ServiceSaver
(service manuals, service memos, wiring diagrams and other documents).

Component descriptions
Components and function description
Here we describe the function and
specification of the most important
components. Certain components are found
only in more highly specified machines or in
particular markets. See the Troubleshooting
chapter for fault and information codes.
CU (Control Unit)
The CU (Control Unit) functions as both a
control panel and a logic component. The
control panel is equipped with knobs/buttons
for selecting programs, Start/Stop buttons and
a display. It is an integrated part of the CU
and cannot be replaced separately. The logic
component manages functions needed for
drying programs and diagnosis. The CU has an
internal power supply for the logic component.
In the event of a fault, the CU can diagnose
a number of components and functions, and
a total of 4 fault codes can be displayed. To
facilitate troubleshooting there is a component
testing function in which the outputs are
activated according to a special sequence.
Power supply
Mains voltage, built-in internal voltage
converter for the logic component.
Thermistors
The thermistors are of the NTC type (Negative
Temperature Coefficient), which means their
resistance decreases as temperature increases.
Thermistor 1 is in the air duct on the front frame,
after the internal impeller. If there is an interruption
in the thermistor circuit or if it short circuits, the
drying program stops and the display shows
“Thermistor fault”.
Purpose: Measures the temperature of the air that
has passed the load and controls the drying process
and the heating element.
Thermistor 2 is on condenser dryers located after the
condenser and on heat pump dryers located on the
evaportator pipe by the comperssor. Purpose: Measures the temperature of the
dehumidified air, the value of which is used as a
parameter in the drying process.
Resistance values for thermistors 1 and 2
Temperature
Light
Certain machines have an internal light
that is activated when the door is opened.
LED technology is used to improve energy
efficiency.

Overheating cut-out
EMC filter
The filter is installed next to the cable fasteners
where the connection cable enters the
machine. The filter consists of a number of coils,
condensers and resistors.
Purpose: To eliminate electromagnetic
interference to and from the machine.
Overflow guard
The overflow guard comprises a microswitch
triggered by a float. When the lower condensed
water container becomes full the float rises and
triggers the microswitch. The microswitch is
normally closed; when activated it opens the
circuit. When the microswitch has been open
for more than 30 seconds, the drying program
stops and the display shows “Over flow”. You
can erase this message by turning the program
selector or pressing the Start/Stop buttons.
Purpose: To provide protection from any
water leaks or flooding from the machine.

Thermostat and overheating cut-out
The thermostat is installed next to the heating
element and is used to reduce the element output
by turning it off if the ambient temperature
exceeds 135°C (±5°C) for condenser dryers and
110°C (±5°C) for others.
The machine is equipped with a overheating
cut-out, which is available in two versions, one
automatically resettable and one manual. The
overheating cut-out switches off the power supply
to all components if the temperature exceeds
150°C (±5°C) and closes the circuit once the
temperature drops below 135°C (±8°C). The
drying program stops and must be restarted if the
overheating cut-out is triggered.
To reset the manual overheating cut-out,
the cover plate on the machines back must be
removed. Press the button on the overheating cutout for manual reset. The automatic overheating
cut-out resets when the temperature drops below
135°C (±8°C) for condenser dryer and 120°C
(±5°C) for others.
Purpose: The thermostat measures
temperature and controls heating element
output. The overheating cut-out controls the
temperature and cuts the power supply if the
machine overheats.

Service Manual TD70
Component descriptions
Door switch
The door switch is located in a holder in the
middle of the front support and is activated by
a pin in the front door. The switch is normally
open and closes when the door is closed. If the
front door is opened during operation the CU
stops the drying program. The program starts
from the beginning if restarted.
Purpose: To prevent the machine from running
while the door is open.
Drainage pump (condenser dryer)
The drainage pump is located in the lower
condensed water container. The condensed
water is pumped to the condensed water
container or directly to the drain. When a
drying program is running, the drainage pump
is activated constantly in cycles of 30 seconds
ON and 210 seconds OFF.
Purpose: To pump condensed water to the
condensed water container or the drain.
Drying motor
The motor is at the bottom and drives the
impeller that is directly fitted to the shaft
journal. The motor is a unit with a belt
tensioner and springs and drives the drying
drum via a poly V-belt.
Purpose: To drive the impeller and drum during
the drying process.
Heating element
The heating element is located in the rear section
and consists of two separate heating coils. Each
heating coil is made from resistance wire.
Purpose: To heat the drying air to the right
temperature.

Heat pump (HP)
Certain types of machine are fitted with heat
pump systems. These systems are closed
circuits that are replaced by replacing the
machine’s base plate with a new module.
The function settings are adjusted in the
service menu.

Heating Water Circuit (HWC)
A certain type of machine is adapted for
connection to the building’s existing heated
water supply (such as district heating) to
reduce energy consumption.
The function settings are adjusted in the
service menu.
Evaporator filter and Auto filter
for Heat pump (HP)
Tumble dryers with heat pump are fitted with
evaporator filter containing a net filter (1A)
and a foam filter (1B). Some dryers can also be
fitted with auto filter, which consists of a water
filter (2), that is located under the condensed
water container.

High ambient temperature combined
with low heater output and low drying

Check whether the customer has:
• Tried spinning at a higher speed.
• Had the machine switched off for 30 minutes
before restarting.
• Good ventilation in the room.
Service action:
• Ensure that the external air has free passage.
After carrying out corrective actions as above, reset the fault indication on the display by switching off the machine
