Cleaning the spray arms

The spray arms can become blocked, especially if the filters are not
inserted correctly in the wash cabinet. This can cause coarse
particles of soiling to get into the wash fluid circulation.
The spray arms must be visually checked daily for any soiling.
To do this remove the mobile unit and the baskets.
Visually check the spray arms for soiling and blocked jets.
Also check that the spray arms can turn easily.
 Immobile or blocked spray arms must not be used again.
In this case contact Miele Service.
The spray arms in the machine as well as in the mobile units and
baskets must be fully dismantled for cleaning:
Remove the mobile unit or baskets from the machine.
The machine upper spray arm is connected by a push-fit connector.
Pull the machine upper spray arm downwards to remove it.
The machine lower spray arm and the spray arms in the mobile units
and baskets are secured with bayonet fittings.
To release the knurled bayonet fittings, turn them in the direction of
the arrow as far as they will go.
Then the spray arms can be removed by pulling them upwards or
downwards.
Mobile unit and basket spray arms with knurled nuts:
The spray arms of older types of mobile units and baskets are
secured with knurled nuts. These must be unscrewed and the
spray arms pulled downwards to remove them.
Metal knurled nuts have a left-hand thread.
Ceramic knurled nuts have a right-hand thread.
