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 wash carts 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.
Cleaning the
spray arms
The spray arms in the machine as well as in the wash carts and
baskets must be fully dismantled for cleaning:
Remove the wash cart or baskets from the machine.
The upper spray arm of the machine is connected by a push-fit
connector.
Pull the upper spray arm of the machine downwards to remove it.
The lower spray arm of the machine and the spray arms in the wash
carts 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.
Wash cart and basket spray arms with knurled nuts:
The spray arms of older types of wash carts 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.
