1. Check the door switchCheck whether the safety lock works. The drum must stop when the door is opened. When the door is closed again, the tumbler must not start until the start button is pressed, fig. 1.

2. Test runLet the tumble dryer work on a program with heat for 5 minutes; then check by opening the door and feeling with your hand whether the heating works.

MaintenanceThe following should be carried out at regular intervals, depending on the frequency of use.

Daily• Check that the drum stops when the door is

opened.

• Check that the lint screen under the door has been cleaned. Use a soft brush or your hand, fig. 2.

• Check that the lint screen is not damaged.

• Check that the tumble dryer will not start until the start/stop button has been activated.

Monthly • Wipe off/clean drum and lifters with citric acid

(Acidum citricum). If soap/softener residue remains, it is recommended also to use a coarse sponge.

Lack of cleaning the lifters can reduce the automatic residual moisture control in the clothes resluting in the clothes being moister than requested when the program has ended, fig. 1.

Quarterly/Semi-annually• Check that the fresh-air intake at the rear of the

tumble is not clogged by lint or blocked in any other way.

• Check that the filter is not broken.

• Clean drum and lifters with a mild detergent (using a sponge) at least once every quarter.

• If the filter is defective it needs replacing.

• At least once a year a skilled expert should check the inside wearing parts of the tumble dryer and clean them of lint.

Air volumeThe curves on the next page shows the characteristics of the dryer. By measuring or calculating the back pressure of the outlet pipe it is hereby possible to find the corresponding air flow into the room and through the dryer and exhaust.

Outlet dimensioningIt is important that the dryer has the correct air volume compared to each dryer’s effect. If the air flow is below the minimum, the dryer will be forced to switch the heating off thus prolonging the time it will take to dry the load.An air flow above the needed is unnecessary and can result in a cold laundry room and noise from the piping and outlet and in extreme cases prolonged drying time.

Electric heated dryersThe electric heating element A is located in the bottom of the chimney, fig. 1.

The air is drawn through the louvres on the back plate and on to the heating element.

The heated air passes through the garments and the drum vents.

Then the air flows from the perforation through the filter and via the outlet into the air.

The heating element is switched on by the heating contactor K4, which is controlled bythe Selecta Control.

Overheating thermostat Electric heated dryers are equipped with two overheating thermostats connected in series (one 180°C and one 90°C) which switches off in case of overheating and error code E08 flashes in the display, fig. 2.

The switching on (reset) must be done manually but first the cause of the error must be detected and the switched off overheating thermostat must be found.

This error is often caused by reduction of the air circulation in the dryer due to insufficient air in the room or due to the dryer being overloaded.

If the dryer is stopped before the cool down sequence has ended the after-heat can cause the overheating thermostats to switch off.

The following error code is related to this section.

E 08 See Selecta Control service manual.

Gas error (E 14)Should a gas error occur error code E 14 willflash on the display, fig. 2.

In general gas errors occur due to supply shortage either if there is a gas failure or the gas pressure is too low.

Other errors which can cause E 14 :

• Ignition failure, check the distance between the electrodes, fig. 3.

The distance must be 3 mm (± 0.5 mm).

• The sensor (the ionization must detect the flame).

• The control box could be defective. Replace the defective control box, fig. 3 & 4.

Gas heating problems often occur due to shortage in the air supply. It is therefore very important that the air supply to the room is sufficient.

A rule of thumb for dimensioning the room’s air inlet is that the air inlet opening must be 5 times the size of the air outlet opening.

To read more about the evacuation system see the installation manual for T4190.

1RMC generalRMC is a measuring method used to stop the dryer when the garments are dry.

The current dryness/moisture of the garments is continuously measured and the drying sequence is brought to an end when the pre-set level has been obtained.

The measuring signal is collected from the steel bands by means of the collector graphies which conduct the measuring signal to the Process Module.

One of the collector graphies is connected to a lifter and the other one to the drum casing. A weak measuring current is sent through the garments which are in touch with the lifter, and as the resistance increases gradually as the garments are getting more and more dry the measuring signal is ready for onward processing by the Control PCB.

Replacing collector graphies1. Demount top plate.

2. Replace collector graphies fig. 2.
