4. How to keep your dishwasher in shape
After Every Wash
After every wash, turn off the water supply the appliance and leave the door
slightly ajar so that moisture and odors are not trapped inside.
Remove the plug
Before cleaning or performing maintenance, always remove the plug from the
socket. Do not run risks.
No solvents or Abrasive Cleaning Products
To clean the exterior and rubber parts of the dishwasher, do not use solvents or
abrasive cleaning products. Rather, use only a cloth and warm soapy water.
To remove spots or stains from the surface of the interior, use a cloth dampened
with water and a little while vinegar, or cleaning product made specifically for
dishwashers.
Moving the Appliance
If the appliance must be moved, try to keep it in a vertical position. If absolutely
necessary, it can be positioned on its back.
Seals
One of the factors that cause odors to form in the dishwasher is food that remains
trapped in the seals.
Periodic cleaning with a damp sponge will prevent this from occurring.
The door should not be left in the open position since this could
present a tripping hazard.
When You Go on Holiday
When you go on holiday, it is recommended that you run a wash cycle with the
dishwasher empty and then remove the plug from the socket, turn off the water
supply and leave the door of the appliance slightly ajar. This will help the seals
last longer and prevent odors from forming within the appliance.
