Troubleshooting
A smear remains on glasses that resembles milk stain which can not be
removed when wiped by hand. A bluish / rainbow appearance occurs when
the glass is pointed to light.
• Excessive rinse aid is used. >>>Lower rinse aid setting. Clean the spilled rinse aid when
adding rinse aid.
• Corrosion has occurred on glass due to soft water. >>> Measure the hardness of the
supply water appropriately and check the water hardness setting. If your supply water is
soft (<5 dH), do not use salt. Choose programmes that wash in higher temperatures (e.g.
60-65°C). You can also use glass protective detergents that are commercially available.
Foam forms in the machine.
• Dishes are washed with hand-wash detergent by hand but not rinsed before placing
them into the machine. >>> Hand-wash detergents do not contain antifoam. There is
no need to hand-wash the dishes before placing them into the machine. Removing the
coarse soil on the dishes under tap water, with a tissue paper or fork will be sufficient.
• Rinse aid has spilled into the machine when adding rinse aid. >>> Take care that rinse
aid is not spilled in the machine when you are filling it. Clean any spilled rinse ait with the
help of a tissue paper/towel.
• Lid of the rinse aid reservoir is left open. >>> Make sure that the lid of the rinse aid
reservoir is closed after adding rinse aid.
Kitchen utensils are broken.
• Dishes are not placed orderly in the machine. >>> Load the dishes as described in the
user manual.
• Baskets are overloaded. >>> Do not overload the baskets in excess of their capacity.
Water remains in the dishwasher at the end of the programme.
• Filters are clogged. >>> Check if the filter system is clean. Clean the filter system
regularly as illustrated in section “Cleaning and Care”.
• Discharge hose is clogged/blocked. >>> Check the discharge hose. If necessary, remove
the discharge hose, clear the blockage and insert is as illustrated in the user manual.
