Frame
Description
The frame is constructed on the free-swinging principle, i.e. the washing
drum is freely and resiliently suspended in the fixed frame.
The entire frame is constructed of U-shaped iron beams forming a stable
and torsionally rigid structure.
The suspension device for the drum unit and motors consists of four posts,
one in each corner, each with a robust spring to which the washing drum
supports are attached. In order to prevent excessively great vibrations
which can be caused by imbalance in the drum, a shock absorber is fitted
between the drum and frame by each spring. (The EX 30 model has twin
shock absorbers at the front.)
Repair instructions
If the out-of-balance cutout is repeatedly triggered
•
Check the shock absorbers, replace them if required. Note that the
shock absorbers should be fitted with the plunger rod upwards.
•
Check the attachment of the springs:
-
the spring is attached by a bolt from above: Check that it has been
properly tightened down.
The entire spring unit should be replaced in spring replacement.
