Cleaning The Machine; Cleaning Machine From Debris In Water, Lint, Scale/Residual Detergent - Electrolux FOM 71 CLS Maintenance Manual

Wascator FOM 71 CLS
Cleaning the machine from debris in water, lint,
scale and residual detergent
It is very important that the wet parts of the machine are free from debris
and particles that can influence the wash performance of the machine.
Lint and threads from ballast and test swatches can accumulate on the
heating elements and as the bundle of lint/threads will grow it may eventu-
ally be so large that is clogging the drain valve and causing the drain valve
to leak. This leakage will definitely influence the wash performance as in the
beginning of the main wash unsolved detergent is located above the drain
valve seat. When leakage occurs the concentrated solution will leak out
reducing the detergent concentration in the bath.
Calcium carbonate from the hard water used in IEC tests will after time ac-
cumulate mainly on the heating elements. If the scale layer is too thick the
heating elements may be destroyed due to the insulating effect of the layer.
Heating power will also be reduced, giving longer heating times.
Lint from the textiles, together with zeolite from the detergent, will accumu-
late on the surface of the outer drum and on the back gable. If the amount
of detergent is too large this can affect the wash and/or rinse results from
the reference machine.
It is advisable not to remove the heating elements only for visual inspection
of any scale or lint. Elements shall only be removed when lint or scale have
been identified in accordance with the inspection procedure. A frequent
removal of the elements will sooner or later result in high resistance in the
wire connection causing too high connector temperature.
Electrical installation must be carried out by an authorized personnel
