THE MACHINE WILL NOT START
Check
• that the outer lid is properly closed.
• that the mains power button is pressed in.

timer program correctly.
• that the condensation water tank is empty.
(TDC44)
• that if a power plug is used it is connected.
• that the fuses for the house electricity supply
are not blown. Change two of the fuses over.
It is not always visible from the outside when
a fuse is blown.
• that the overheating protection has not trip-
ped, see below.
OVERHEATING PROTECTION
The overheating protection switches off the tum-
ble drier if the temperature is too high, e.g. be-
cause fluff is blocking the fluff filter. Clean the
filter, empty the condensation water tank and cle-
an the condenser. Then reset the overheating pro-
tection by pressing on the rubber membrane at
the rear of the machine.
Overheating protection tripped even though
fluff filter and condenser unit have been
cleaned.
1. Fault in control unit
2. Fluff in internal fan wheel - clean also air ducts
and behind the element.
3. Motor overheating protection tripped.
ERROR MESSAGES
The display text field shows a message if a fault
occurs during the time the program is running.
The error messages that may be shown are:
Maximum program time: When the machine
has been running for its maximum time (3 hours)
it will stop.
This can have several independent reasons, or a
combination of these.
1. Mains power fuse has blown
2. Fluff in the filter, condenser unit or fan hou
sing.
3. Incorrect connection to single phase, 10A
4. External air is restricted or blocked, resulting
in poor condensation
5. High ambient temperature + low heating ele
ment power + low drying temperature resul
ting in poor condensation
6. Low ambient temperature + low heating ele
ment power + low drying temperature so that
it is difficult to get the dampness out of the
clothes .
7. The washing has been spun dry at low speed,
i.e. less than 800 rpm
8. The washing has been taken out before the
program was completed. The machine was
then loaded with a new batch of washing. In
that case the control unit did not have time
to reset itself and the time was added to the
next drying cycle.
9. Damaged humidity sensor, its wiring or con
nections.
To remove the error message, switch off the mach-
ine or open its door.
Thermistor error: Thermistor fault, change ther-
mistor.
Sensor error: Fault in the humidity sensor.
This error message may also appear if you run
the machine with laundry that is already dry, or
run it empty.
Open the door and the message should disappear.
Overfull: (TDC44) Means that the condensation
water tank is full. Empty it and restart. If the same
error message appears again, it can mean that the
