The warm and cold air circuits cross inside the heat exchanger, which results in a thermal exchange which condenses the humidity contained in the warm air. The condensation which forms in the heat exchanger is collected in a sump, from which it falls by gravity into a tank. When the water in the tank reaches the max. level, the level of the water in the sump increases, which causes the float to move upwards, thus actioning a microswitch; The microswitch for dryers with electronic board sends a signal to the electronic circuit when the tank has been filled, switches off the appliance and lights a pilot lamp which indicates to the user that the tank is full. The microswitch with electromechanical control switches off the dryer (the timer motor is powered and ends its cycle) and lights a pilot lamp which indicates to the user that the tank is full.
The tank capacity is about 3.5 lt., enough for a drying cycle.
- Remove the screw (1) which secures the support micro and use a screwdriver for the two hooks which secure it to the sump.
- Lift them simultaneously and unthread the micro support towards outside
Putting upside down the support you can access the floating microswitch.
Inside the sump there is the float.
To extract it rotate the float 90° clockwise as shown.
Lift it up, rotate it towards outside and extract it.
While reassembling the pump, the float and the tank microswitch, repeat the same operations backwards, paying attention that when the micro support is remounted it is necessary to use a screwdriver in the fissure (indicated by the arrow), to lift the micro lever and lean it over the float (if this operation is not carried out the lever of the micro comes up alongside the float (it deforms) and the two components do not function anymore.
I have the same problem. In addition to which the water seems to be simply draining onto the floor beneath the machine. I cannot see how to get to the float or the water tank. The machine seems to be rivitted together. The water tank never gets full because water simply leaks onto the floor. I noticed a white valve at the back of the machine and pulled it out, and water came pouring out. Why is this water not going into the resevoir? I now have the machine elevated on blocks with the back valve open and draining into a cup, so that the machine will work. Any suggestions?
