PROBLEMS
COMMON QUESTIONS AND PROBLEMS
Yhe machine only runs for 20 minutes?
1. Mains power fuse has blown.
2. Overheating, fluff blocking the filter, conden-
ser unit or fan housing.
3. Overfilling: The display shows "Fault indica-
tion, filling"
4. The machine does not reach the measured
value of 1,8 mV within 15 minutes.
This can be due to:
- Incorrect connection to single phase = too
low heating element power (720 or 600 W)
- Incorrect connection of element to control
unit
- Incorrect connection in element terminal
block
- Humidity sensor not located in fan hous
ing
- Faulty humidity sensor
- Heating element open circuit
5. Drive belt running incorrectly on motor shaft
= too high drum speed > 56 rpm
The washing will not dry?
1. Air leakage around the moisture sensor sea will
cause incorrect drying operation. / Verify the
seal.
2. Incorrect setting in moisture sensor. (The sen-
sor is sensitive to impact)/ Replace it.
3. Air leakage at door seal will cause incorrect
drying operation. / Verify the seal.
4. Air leakage around the motor shaft (loose seal,
incorrect setting) will affect the drying result
when the “Iron dry” programme is used. /
Verify the seal.
Uneven drying results
1. Mixing different types of garments may re-
sult in uneven drying results. (E.g. thick terry
towels with thin garments of cotton/polyes-
ter)
2. The tumbler load also affects the drying re-
sult. If the tumbler is filled (5 kg) with e.g.
jeans, the drying result could be uneven. The
garments in the tumbler must have sufficient
space to tumble.
PROBLEMS
Tumble drying is taking too long
Check that the fluff filter is not blocked.
1. Check that the fluff filter is not blocked.
2. TDC44: check that condenser are not bloc-
ked.
3. Spinning the garments in the washing mach-
ine affects the drying time. Spin at at least 800
revolutions. A short spin cycle at 800 revolu-
tions is not recommended.
4. A tumbler dryer has a very high air exchange
level. Small spaces can heat up quickly, pro-
longing the drying time. Be sure there is suf-
ficient ventilation where the machine is
installed.As an example, open the doors to
other rooms.
5. Heating elements with low power (single pha-
se, 10 A) also prolongs the drying time.
6. TDC33: The length of and number of bends
on the evacuation hose affects drying opera-
tion. Try to use a hose as short as possible and
if bending is needed soften the bends.
Low points in the hose can create water pock-
ets and block the airflow.
