What to do if the sterilization process phase of a sterilization cycle was longer than expected in W&H Laboratory Equipment?
If the sterilization process phase was longer than expected, it may be because the chamber temperature dropped below the minimum threshold and the software performed a successful recovery. Wait for the cycle completion.
What to do if W&H Laboratory Equipment is leaking water at the front?
If you see water leaking at the front of the W&H sterilizer, it could be due to leaks through the chamber door seal. Try cleaning or replacing the door seal and cleaning the chamber face side. If the leak persists, it might be an internal leak, and you should call technical service.
Why does W&H Laboratory Equipment chamber door lock and reopen immediately?
If, when starting a cycle, the chamber door locks but re-opens immediately and the 'Open the door' message appears on your W&H Laboratory Equipment, make sure the door seal is evenly inserted on the entire circumference. Also, remove any objects interfering with the chamber door and ensure the door isn't forced against the load or chamber furniture.
How to prevent corrosion on instruments in W&H Laboratory Equipment?
If instruments are showing corrosion or spots after sterilization in your W&H Laboratory Equipment, ensure that instruments are dry before placing them in the sterilizer. 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, wash the chamber furniture, and ensure that instruments of different materials do not touch. Also, clean the chamber to remove any scale deposits.
Why is there residual water in W&H Lisa VA131-22 after cycle?
If, at the end of the cycle, there is residual water in the chamber of your W&H Laboratory Equipment, first ensure the sterilizer is properly leveled. Then, comply with the maximum load weight limits and always use the chamber rack for trays and cassettes. Remove and clean the chamber filter, and ensure the chamber filter cap is well-positioned.
What to do if the W&H Laboratory Equipment cycle commences but there is no pressure/temperature rise?
If the cycle starts but pressure and temperature don't rise, the safety thermostat switch might be open. Try resetting the safety thermostat switch.
What to do if instruments are turning brown or black in my W&H Lisa VA131-22?
