Introduction

You are holding the Service manual for the TD70 tumble dryer. The TD70 tumble dryers is

available in several models, designated TD70.1, TD70.2, TD70.3. The TD70.C model, that this

guide is focusing on, is designed for professional use.

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 manual 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?

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 guarantee conditions and the fact that the customer will be charged for the callout.

Yes

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, circuit diagrams and other documents).

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 programmes, 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 programmes 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 programme 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.

Service Manual TD70.C

Cover plate (658 x 483 mm)

Tolerance:฀±1%

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 programme 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 over-

heating cut-out 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.

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

programme stops and the display shows “Over

ﬂow”. You can erase this message by turning the

programme selector or pressing the Start/Stop

buttons.

Purpose: To provide protection from any

water leaks or ﬂooding from the machine.

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 programme. The programme

starts from the beginning if restarted.

Purpose: To prevent the machine from running

while the door is open.

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.

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 programme 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.

Light

Certain machines have an internal light

that is activated when the door is opened.

LED technology is used to improve energy

efﬁciency.

Service Manual TD70.C

Component description

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.

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.

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.

with low heater output and low

drying temperature leads to poor

condensation formation.
