Periodic Checks; Lengthy Periods Out Of Use - Smeg CW500 Manual

Remove the filters (simply lift them out as shown here), taking care that no
large residues fall into the sump underneath. Clean them to remove residues
and rinse with plenty of water, then put them correctly back in place; do not
use sharp or pointed tools.
Clean away any limescale deposits to prevent excessive build-ups;
If possible, leave the door ajar when not in use;
‐
Clean surfaces thoroughly and often with a damp cloth; use neutral,
‐
non-abrasive detergents which do not use chlorine compounds, which
corrode and damage stainless steel.
Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the
dishwasher, to ensure that fumes or drops cannot damage the steel surfaces.
IMPORTANT: The dishwasher automatically performs program "P0" at the start of the day if water has been
left in the tank and has dropped below the temperature of 40°C

11.2 Periodic checks

Remove the top and bottom spray arms by unscrewing the central screw and unscrew the caps from the ends of
the rinsing arms as shown. Do not unscrew the nozzles.
Clean the holes and nozzles under a jet of clean running water; do not use tools which might cause damage.
Reassemble the spray arms with care.
Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.

11.3 Lengthy periods out of use

If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser
devices must be emptied to prevent crystallisation and damage to the pumps:
from the detergent and rinse aid containers and place them in a container of clean water, then perform a few wash
cycles followed by a complete pump-out.
Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is
completely dry. The detergent and rinse aid intake hoses must be put back into the containers when the
dishwasher is returned to service, taking care not to swap them over (red hose = detergent, blue hose = rinse
aid).
