Do I need to carry out periodic testing on my W&H Sterilizer?

All W&H sterilizers features test cycles (B&D/Helix test, Vacuum test). Compulsory and frequency of testing are regulated by local/national guidelines.

Validation is a series of tests carried out with the use of independent specialist test equipment, as is necessary to demonstrate that the physical conditions required for sterilization, thermal disinfection and/or cleaning (i.e. temperature, pressure, time) are achieved.

Do I need to document the results of all periodic tests?

Yes, all tests performed by the operator or user should be recorded in a logbook with the date and signature of the individual how carried out the test. Every Sterilizer and every thermo washer disinfector should have a logbook (file) in which test details pertaining to the lifecycle of the equipment (from purchase - disposal) are recorded. A logbook is provided as standard with the Premium Careplus Service Contract from W&H, or as an optional extra with the Premium Care Service Contract.

How long should I Keep periodic test records?

Under current national decontamination guildance, all audit documents should be stored for at least two years and they should not be removed from the premises or destroyed.

Does my Lisa/Lina need to be commissioned from new?

Yes, validation is needed for new equipment at installation and annually thereafter. It will also be necessary to validate equipment after any major repairs have been carried out.

Who should I use to carry out validation and maintenance on my Lisa/Lina?

All validation and maintenance should be undertaken by the Competent Person (Decontamination) or Competent Person (maintenance).

How do I change consumable components on my sterilizer?

Consumable replacement instructions are provided in the Instructions for Use, chapter “Maintenance”. In addition, a video description is available: • in the sterilizer, in the maintenance section of the menu; • in the Consumables & Accessories and Video Tutorial section of this website.

How do I clean the water tanks and what products should I use?

Water tank cleaning instructions are provided in the Instructions for Use, chapter “Maintenance”. In addition, a video description is available: • in the sterilizer, in the maintenance section of the menu; • in the Consumables & Accessories and Video Tutorial section of this website.

How often should I de-scale my Thermoklenz?

Water hardness can differ depending of the region in which the unit is located. Carrying out a water hardness test will enable you to gauge how hard the incoming water is. The frequency of de-scaling cycles will depend on the water hardness and the number of cycles run per week. W&H recommends that at least one de-scaling cycle be run each week. More frequent de-scaling cycles should be run if the washer disinfector has a heavier workload or if the water is hard. Additional information relating to these tests and how to carry out these tests can be found on the Video Tutorial section of this web site.

What water quality should I use with my Lisa/Lina?

The water quality for sterilizers is internationally specified by standards and directives. The reasons for this are that your sterilizer can be seriously damaged by it or the sterilization can be jeopardised. Consequently, only water with conductivity of less than 10 µS/cm in North America and 15 µS/cm for the rest of the world should be used for your W&H sterilizer. The Water treatment devices Multidem and Osmo are especially designed to prepare suitable water (see chapter “Water quality” in the Instructions for Use).

Should I pre-wrap and how long can I store my instruments after sterilization?

Under current UK decontamination guidance, with a type B vacuum cycle, instruments should be pre-wrapped and once sterilized can be stored for up to 12 months. Wrapping should take place shortly after washing and disinfection. Under current UK decontamination guidance, with a type N cycle, instruments should not be pre-wrapped. Once sterilized, instruments can be immediately aseptically wrapped and stored for up to 12 months. Instruments should always be dry before they are placed in the purpose-designed packaging.

Lisa 17/22 The sterilizer remains switched OFF.

POSSIBLE CAUSE The main switch or network circuit breaker is OFF SOLUTION Activate the main switch or network circuit breaker (ON). POSSIBLE CAUSE No voltage at the socket SOLUTION Check the electric circuit. POSSIBLE CAUSE The power cord is not connected properly SOLUTION Check and connect the power cord properly.

Lisa 17/22 Water is leaking at the front of the sterilizer

POSSIBLE CAUSE Leaks through the chamber door seal SOLUTION Clean or replace the door seal. Clean the chamber face side. POSSIBLE CAUSE Internal leak. SOLUTIONS Call technical service.

Lisa 17/22 When starting a cycle, the chamber door locks but re-opens immediately. The “Open the door” message appears.

POSSIBLE CAUSE Door seal not properly placed; seal sticking out SOLUTION Ensure that the door seal is correctly inserted around the whole circumference. POSSIBLE CAUSE Door jammed by external objects or by the load itself SOLUTION Remove any objects interfering with the chamber door. Check that the door does not push against the load or the chamber furniture.

Lisa 17/22 The sterilizer enters into “Sleep mode” immediately after opening the chamber door.

POSSIBLE CAUSE The chamber door has not been opened after the previous cycle had finished and the “Sleep mode delay” has expired SOLUTION Press the SLEEP MODE button to exit”.

Lisa 17/22 No cycles are stored in the cycle history menu

POSSIBLE CAUSE An electronic board was replaced by service. SOLUTION None. The memory of the old board cannot be restored. Save periodically the history on the USB pen drive.

Lisa 17/22 Corrosion or spots on instruments

POSSIBLE CAUSE Tap water on instruments when placed in the sterilizer SOLUTION Ensure that instruments are dry before they are placed in the sterilizer. POSSIBLE CAUSE Use of water of poor quality or water containing chemical substances SOLUTION Drain both water tanks. Use water of good quality (see ANNEX 7). POSSIBLE CAUSE Organic or chemical residues on the instruments SOLUTION Clean, rinse and dry instruments before placing them in the sterilizer (see ANNEX 2). POSSIBLE CAUSE Chamber, trays, tray rack dirty SOLUTION Clean the chamber and wash the chamber furniture POSSIBLE CAUSE Contact between instruments of different materials SOLUTION Ensure that instruments of different materials do not touch (aluminum, carbon or stainless steel, etc.); place them on different trays or cassettes or pouch them (refer to ANNEX 2). POSSIBLE CAUSE Scale deposits on the chamber SOLUTION Clean the chamber and use water of good quality (refer to ANNEX 7).

Lisa 17/22 At the end of the cycle, there is residual water in the chamber

POSSIBLE CAUSE Sterilizer not properly levelled SOLUTION Properly level the surface the sterilizer is placed on. POSSIBLE CAUSE Overloaded chamber SOLUTION Comply with the maximum load weight limits for each type of load. Always use the chamber rack for trays and cassettes. POSSIBLE CAUSE Chamber filter clogged SOLUTION Remove and clean the chamber filter. POSSIBLE CAUSE Chamber filter cap mispositioned SOLUTION Mount the chamber filter cap properly (see chapter MAINTENANCE) POSSIBLE CAUSE Load incorrectly placed SOLUTION Follow the recommendations as listed in ANNEX 2.

Warning about saving to the USB (HTML and SCL files).

Lisa 17/22 When the sterilizer is connected to an automated water supply system: there is no clean water in the tank, but the automatic water filling does not fill the water.

POSSIBLE CAUSE Water fill system not connected SOLUTION Connect the water fill system to the sterilizer (see ANNEX 7 for water quality requirements). POSSIBLE CAUSE When the water fill system attempted to fill the tank, water was temporarily unavailable SOLUTION Since water tank filling is attempted only once in-between cycle execution, this event inhibits water feeding. Switch the sterilizer OFF and then ON again. Check the external water supply system. Check for water leaks from the sterilizer. POSSIBLE CAUSE Faulty MIN water level sensor in the clean water tank SOLUTION Call service.

Lisa 17/22 The cycle report printer does not work.
