7. Remove the 4 Allen head bolts

from the counter weight. Remove the counter weight.

8. Mark the position of the front

drum panel against the sensor plate perpendicularly.

9. Release the clamps of the front

drum panel. Mind the shape of the clamps so they are not deformed by the action – Do not hammer them, just push them! OR


of 19 Item-ref.: 529252

Use a strong wire to pull them off from the front panel and avoid clamp deformations.

10. Remove the front panel.

A screwdriver can be used to loosen the front panel from the drum. Be careful to avoid any damage. Any damage will result in leaking.

11. Inspect the rubber sealing of the

front panel. If it is in good condition, verify it sticks on through its groove. If it is loose on some places, re-glue it using a SMALL quantity of silicone and let it dry. If the sealing rubber is NOT in good condition, remove the sealing from the front panel, clean the groove and adhere a new sealing #PRI504000031. Use silicone. When gluing the sealing, make sure it is not bent or warped and that it fits perfectly all around without sticking out. Respect the necessary drying time.
