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.

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).

Component description

Components and function description

Here we describe the function and speciﬁcation of the most impor tant components. Cer tain 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.

Personal notes

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.

Thermostat

Overheating cut- out

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 overheating cut-out for manual reset. The automatic overheating

Cover plate (658 x 483 mm)

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.
