Removal of scale
Depending on how the reference machine is to be used, wet parts should
be descaled on a regular basis.
• To remove and prevent the formation of scale in instances where the
machine is used in a hard water area, implement the following proce-
dure:
o Put 0.5 kg of citric acid in the detergent department.
o Start program Cotton 85ºC.
o Rinse the reference machine again by running the Cotton 85ºC pro-
gram.
Removal of residual detergent
Detergent may accumulate in certain parts of the machine and may also
form part of deposits on the inner side of the outer drum.
• Detergent may accumulate in the hose between the drum and the exter-
nal tap valve. Remove the valve and clean the hose using bottle cleaner.
Flush the hose with water to ensure that no detergent remains.
• Detergent may also accumulate in the hose between the drum and the
external level glass. Clean the glass and hose using bottle cleaner. Flush
the hose with water to ensure that no detergent remains.
• Run a Cotton 85°C or Cotton 60°C program with the machine empty and
without detergent on a regular basis. If foam is visible during the main
wash, repeat the Cotton program until no "stable" foam is visible.
