The dryer is switching to safe mode
Sometimes your tumble dryer can switch into safe mode, meaning it cannot be used. There are several possible causes, ranging from maintenance to faulty parts. Here are 7 of these causes:
POTENTIAL CAUSES OF THIS FAULT:
-
Air circulation fault (clogged filter and condenser)
-
Drum problem
-
Door not closed properly
-
Faulty thermostat
-
Maintenance fault
-
Water reservoir full
-
Blocked or clogged drainage pump
WARNING
For safety reasons, we recommend that you disconnect your tumble dryer from the mains before performing any work on it.
Air circulation fault (clogged filter and condenser)
Shouldyour dryer's filter become clogged, the appliance will switch to safe mode and will stop working properly. In this case, you must check that the filter statut light is off. If it lights up or flashes, this means that the filter needs cleaning. Textile residues can accumulate in the appliance, which will then becomes faulty and power consumption will increase. Your machine will therefore require a longer drying cycle.
It is important to clean the filter of your dryer after each drying cycle to prolong the life of your machine. If the condenser is clogged or if the filter is not cleaned after each use (it is important to clean these parts after each drying cycle), these dirty parts will trigger the safety thermostat (= which will cut out).

Drum problem
The first thing to do is check that the drum of your device is spinning correctly.
Overwise, the safety thermostat may have been triggered and the dryer will no longer work. Be sure to check the condition of yout appliance's belt.
Door not closed properly
Sometimes a simple porthole door that has been improperly closed or that is faulty will cause the appliance to overheat (indicator light on).
Before starting your cycle, make sure that there is no clothing preventing the door from closing fully.
In the event of even a slight obstruction, the cycle will not start and will prevent the start of the drying program. If the porthole door is closed properly but does not lock, it may be that the door lock is faulty. In this case, the door lock will generally have to be replaced.
Faulty thermostat
The safety thermostat is a thermal safety device that generally cannot be reset, i.e. it cannot be put back into operation once it has been triggered.
If it is triggered, it will prevent your appliance from overheating. This part can be easily checked with a multimetre set to the Ohmmeter position. First, identify where the safety thermostat is located (it will normally be behind the drum, close to the heating element). Next, disconnect all the connectors and place the meter's two probes onto both of the element's terminals to check that it definitely has continuity. If there is no continuity, it will have to be replaced or, if possible, reset.
WARNING : on some models, there may be several thermostats, as well as a sensor.
The thermostats pass current to the Ohmmeter while the sensor delivers a value based on the temperature.

Maintenance fault
Failure to maintain your appliance may result in multiple faults.
If your tumble dryer or certain parts are dirty, air will no longer circulate properly, which can cause the appliance to overheat, in turn triggering the safety thermostat around the heating element. In this case, the thermal safety device intended for this purpose will cut off the power to the heating elements, and to the electric motor, which will cause your tumble dryer to automatically switch to safe mode.
If there is an "overflow" from the reservoir, this can trigger a malfunction, which is generally indicated by a light on the control panel.
Water reservoir full
Safe mode can also be triggered if the water reservoir is too full.
In this case, empty it after each drying cycle. It is important to check and then clean clean the drainage pump circuit, and remplace it if the problem persists.
Tip : Check and empty the water tank at the beginning and end of each programme.
Blocked or clogged drainage pump
The drainage pump on a tumble dryer enables the drainage of condensation water to the water collection tank. If this is clogged or blocked, the safety float will tilt and move to the safety mode position: the cycle will stop. This information is usually indicated on the control panel.
