Endoscope Washer Disinfector Validation (EWD/AER)

Validation, maintenance, periodic testing and record keeping are necessary to demonstrate that the endoscope washer-disinfector is functioning correctly and that it will produce cleaned and disinfected loads consistently.

ENISO15883 Part 4 specifies the general requirements for performance of these washers.

The washer must meet specific performance requirements relating to Cleaning, Disinfection and Final Rinsing.

Critical parameters for Cleaning and Disinfection include water pressure, water flow, temperature, detergent delivery time/flow/amount, leak test result, channel patency and disinfectant delivery time/flow/amount.
