Whirlpool SDD 534 U Manuel D'instructions page 27

Never use the following types of products to clean the tank and the steel surfaces:
- Products containing chlorides or hydrochloric acid
- Bleach
- Products for cleaning silver
- Scouring pads or metal sponges
NB: the incorrect use of the afore-mentioned products may cause rust marks on the surfaces.
Long-term stoppage
If the dishwasher is not going to be used for quite some time, you have to empty the detergent and rinse aid dispensing device
to avoid crystallizations and damages to the pumps: remove the priming pipes from the detergent and rinse aid containers and
soak them in a container of clean water, run some wash cycles and empty the machine completely.
To finish, switch off the main on/off switch and shut off the water inlet tap; only put the detergent and rinse aid priming pipes
back into their containers when you start the machine again, making sure not to invert them (red pipe=detergent; clear pipe =
rinse aid).
Do not leave the dishwasher switched on if it is not used for some time or if the operator is not able to monitor it directly.
