W&H Lexa Mini Error Codes 100-150
Understanding the error codes that may arise while using any autoclave is crucial for ensuring its optimal performance and reliability. So in this article, we will delve into some of the
various error codes of the W&H Lexa Mini. Specifically, we’ll be going over Error Codes 100-150. These are not the error codes that we’ve previously shown in our original article here. These is an updated version of W&H’s official troubleshooting manual with new types of error codes. So in this article, we’ll go over the details of what each code means, as well as actions you can take to troubleshoot them.
For visual learners, we have a video on these specific error codes on our YouTube channel here. If you have any questions about these error codes, the W&H Lexa Mini or anything else, please give us a call at 704-966-1650 Option 3 for our Free Tech Support Line.
Error Codes
Error Code 100-103
Timeout of the pressure phase (PPx)
Possible Cause 1:
Steam leak from the door gasket.
Action:
Check the door gasket and the chamber face side for damage or dirt. Clean and replace door gasket, if needed. Run a sterilization cycle. If the problem persist, see next possible cause.
Possible Cause 2:
Steam leak from an electro valve.
Action:
Call in
Possible Cause 3:
Other steam leak.
Action:
Run the vacuum test in the prescribed conditions (cold and dry circuit)
Possible Cause 4:
Failure in the steam generator heating element.
Action:
Check if the heating element works properly
Error Code 120, 121
Description
Unexpected pressure reading or pressure reading error during door opening
Possible Cause:
Pressure sensor failure.
Main board failure.
Action:
Depressurize the chamber artificially (activate the chamber safety valve manually). If the problem persist, see error 089 to 098 and perform the relevant test.
Error Code 130
Description
Unexpected pressure reading or pressure reading error during door opening
Possible Cause 1:
Chamber temperature sensor misplaced.
Action:
Check and restore the position of the temperature sensor. Use the dedicated tool F190101X.
Possible Cause 2:
Pressure sensor failure or not calibrated.
Action:
In the Cycle Info screen, check the pressure readout at atmospheric conditions.
See Test Instructions service book, chapter SPECIFIC TESTS FOR INDIVIDUAL COMPONENTS, Pressure sensor.
Replace the pressure sensor if necessary.
Possible Cause 3:
Sensors not calibrated.
Action:
Calibrate the sterilizer and follow the next possible cause.
Possible Cause 4:
Chamber temperature/pressure sensor failure.
Action:
Call in to our free tech support line.
Note: If a sensor is broken, replace it. If the test passes, and the error persists, replace the main board.
Error Code 131
Description
Difference between theoretical and chamber temperature > 2°C
Possible Cause 1:
Chamber temperature sensor misplaced.
Action:
Check and restore the position of the temperature sensor. Use the dedicated tool F190101X.
Possible Cause 2:
Pressure sensor failure or not calibrated.
Action:
In the Cycle Info screen, check the pressure readout at atmospheric conditions.
See Test Instructions service book, chapter SPECIFIC TESTS FOR INDIVIDUAL COMPONENTS, Pressure sensor.
Replace the pressure sensor if necessary.
Possible Cause 3:
Sensors not calibrated.
Action:
Calibrate the sterilizer and follow the next possible cause.
Possible Cause 4:
Chamber temperature/pressure sensor failure.
Action:
Call in to our free tech support line.
Note: If a sensor is broken, replace it. If the test passes, and the error persists, replace the main board.
Error Code 140
Description
Theoretical temperature is too low.
Possible Cause 1:
Steam leak from the door gasket.
Action:
Check the door gasket and the chamber face side for damage or dirt. Clean and replace door gasket, if needed. Run a sterilization cycle. If the problem persist, see next possible cause.
Possible Cause 2:
Steam leak from an electro valve.
Action:
Call in
Possible Cause 3:
Other steam leak.
Action:
Run the vacuum test in the prescribed conditions (cold and dry circuit)
Possible Cause 4:
Failure in the steam generator heating element.
Action:
Check if the heating element works properly
