Illustration 18:
Check that the distance illustrated is max. 0.5 mm. If not, the reason could be:
1. The O-ring outside the level ring is not in the downwards position or the O-ring is located under
the level ring.
2. Two washers are fitted under the centre screw fixing the bowl to spindle.

by hand. Never overtighten when assembling parts.
