How to fix a W&H Laboratory Equipment sterilizer that remains switched OFF?
If your W&H Laboratory Equipment sterilizer remains switched off, first, ensure the main switch or network circuit breaker is turned on. Then, check the socket for voltage and verify that the power cord is correctly and securely connected.
What to do if water is leaking at the front of my W&H Lyla sterilizer?
If you see water leaking from the front of your W&H Laboratory Equipment sterilizer, it could be due to leaks through the chamber door gasket. Try cleaning or replacing the door gasket and cleaning the chamber face side. If the issue persists, it may be an internal leak, and you should call technical service.
What to do if my W&H Laboratory Equipment sterilizer displays “Open the door” but I can't open it?
If your W&H Laboratory Equipment shows “Open the door” but opening the door is impossible, it may be in vacuum due to an internal malfunction. Refer to "Emergency door opening" on the next page. Switch the sterilizer OFF: this releases any internal pressures allowing the chamber door to be opened. If the problem persists, call technical service. Alternatively, the bacteriological filter might be blocked. Remove it to release the pressure and then replace it. Note that these filters need replacing every 400 cycles.
What to do if the chamber door of my W&H Laboratory Equipment sterilizer locks but re-opens immediately?
If, when starting a cycle, the chamber door of your W&H Laboratory Equipment locks but immediately re-opens, displaying the “Open the door” message, first check that the door gasket is evenly inserted around its entire circumference. Also, ensure that no external objects or the load itself are jamming the door.
Why is there residual water in the chamber of my W&H Lyla sterilizer after a cycle?
If, at the end of a cycle, you find residual water in the chamber of your W&H Laboratory Equipment sterilizer, make sure the sterilizer is properly leveled. Also, check that you have not overloaded the chamber, complying with the maximum load weight limits for each load type. Ensure that you always use the chamber rack for trays and cassettes. A clogged chamber filter could also be the cause, so remove and clean it. Finally, ensure the chamber filter cap is correctly positioned. Check that the load is correctly placed.
Why are instruments turning brown or black in my W&H Lyla Laboratory Equipment sterilizer?
If instruments are turning brown or black in your W&H Laboratory Equipment sterilizer, it could be due to an incorrect temperature selection. Select a sterilization cycle featuring a lower sterilization temperature and follow the instrument manufacturer's instructions.
Why is there corrosion or spots on instruments after using my W&H Laboratory Equipment sterilizer?
If you notice corrosion or spots on instruments after using your W&H Laboratory Equipment sterilizer, ensure that instruments are dry before placing them in the sterilizer. Also, drain both water tanks and use water of good quality. Clean, rinse, and dry instruments to remove any organic or chemical residues before sterilization. Clean the chamber, trays, and chamber rack. Ensure that instruments made of different materials do not touch each other by placing them on separate trays or in pouches. Finally, clean the chamber to remove any scale deposits and use water of good quality.
What to do if my W&H Lyla Laboratory Equipment sterilizer cycle starts but there is no pressure or temperature rise?
If your W&H Laboratory Equipment sterilizer cycle commences but there is no pressure or temperature rise, the safety thermostat switch might be open. Reset the safety thermostat switch. If the problem persists, it may be an electric or electronic fault, and you should call technical service.
How to fix a W&H Laboratory Equipment cycle report printer that does not work?
If the cycle report printer is not working with your W&H Laboratory Equipment, check the data and power connections to the printer.
What to do if my W&H Laboratory Equipment sterilizer's automatic water filling system is not working?
If your W&H Laboratory Equipment sterilizer is connected to an automated water supply system and there is no clean water in the tank, but the automatic water filling is not working, first, ensure that the water fill system is properly connected to the sterilizer. If it is connected, switch the sterilizer off and then on again. Check the external water supply system and check for water leaks from the sterilizer. If the problem persists, it may be due to a faulty MIN water level sensor in the clean water tank, and you should call service.
