All surfaces (internal and external) of the endoscope(s) which are required to be disinfected by the WD shall be cleaned.
NOTE Some endoscope(s) have component parts (e. g. electronic connectors) which their manufacturer recommends should not be immersed in water or aqueous solutions. These component parts will be processed in accordance with the manufacturers instructions and then protected from immersion during processing in the WD (see 5.1.2).
Cleaning shall comprise washing with a detergent solution which may, when necessary, be preceded by flushing. Washing shall be followed by rinsing unless the conditions specified in 4.1.3 have been met.
