COMMON QUESTIONS AND PROBLEMS
The washing will not dry?
The 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
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.
Overfilling fault indication, even though tank
is empty.
Condenser water pump is blocked or burned out.
If the pump is burned out an associated fault will
be burned wiring in the control unit. Always check
first if the condenser water pump has burned out
before installing a new control unit.
See service bulletin Group 22 Number 21.
The machine shows the Maximum program
time fault indication.
The indication means that the machine has been
running for the maximum time (= 3 hours) that
the control unit is allowed.
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.
