Door
Check that the door seal closes tight and is undamaged and that there is no leakage while a
program is running. Clean or replace the seal if necessary.

Check that the suction hose and pump are full of detergent or rinse-aid before running a
program. When the pre-programmed amount of detergent is changed, the consumption must be
checked with a measuring glass.

• Check that the washing arms can rotate freely.
• Check that the holes in the washing arms are not blocked. Clean when necessary.
• Check that the coarse strainer in the bottom of the washing chamber is correctly installed.
Clean when necessary.
• Check that all couplings connecting the washing system to the pump and chamber are
leaktight. Tighten and seal if necessary.
Temperature check
• Check the temperature during a program run. Compare time and temperature with the program
sheet. Time and temperature are especially important in the disinfection phase.

High-performance equipment is essential for reliable measuring results, because of the
relatively rapid temperature changes.
Only one measuring point in the centre of the machine is need for the function check.
Note:
Washer-disinfectors that have been shown not to meet the requirements in terms
of temperature, sequence, washing system and safety must not be used until the
faults have been corrected.
Dryer
• Check seals and hoses for leaks once a year.
• Replace the sterile filter if necessary or in the event of an alarm.
Printer (extra equipment)
• Check ink ribbon cartridge
