Autoclave Troubleshooting Guide for Lab Professionals
Autoclaves are essential workhorses in any lab and dental clinic, but what happens when your autoclave door wont open and wont turn on? Don’t panic! This guide helps you troubleshoot common issues, including:
Part 1: Common Problems & Fixes
1. Clogged Drainage Port
Symptoms: Water won’t drain due to debris (glass fragments, paper scraps) or agar buildup.
Quick Fix: Open the drain valve. Use a rubber bulb or syringe to blow air backward through the drain pipe to dislodge blockages.
For agar clogs:Run the autoclave until it reaches 100°C, then shut it down.
Wait until pressure drops to 0MPa before carefully opening the drain valve.
⚠️ Safety first: Wear heat-resistant gloves to avoid burns.
Still stuck? Contact a certified technician.
2. Mid-Cycle Shutdown
Possible Cause: Low water levels triggering the dry-run protection.
Action: Refill the chamber to the marked water line.
Restart the cycle. Power outage? Simply reboot the system once electricity resumes.
3. Autoclave Won’t Start
Likely Culprit: The lid isn’t fully sealed.
Solution: Double-check the lid alignment and locking mechanism.
Close it firmly and try restarting.
4. No Heating/Insufficient Temperature
Signs: The autoclave runs but fails to hit 121°C, or circuit breakers trip during startup.
Probable Issue: Faulty heating element.
Response: Stop using immediately to prevent safety risks.
Contact your maintenance provider for replacement.
Part 2: Decoding “E” Error Codes
Seeing an “E” code flash? Stay calm—most errors are fixable with these steps:
Check the Manual First
First, we recommend that you consult the user manual that came with your device, which will usually have detailed explanations and responses to various “E” codes;
Follow On-Screen Prompts
Follow the prompts and handling suggestions for the “E” code and complete the corresponding steps. For example, if the code indicates a door interlock failure, check whether the handle is in place or whether you need to contact the dealer;
Perform Basic Maintenance
If the “E” code reminds you to perform maintenance, such as cleaning the exhaust solenoid valve or replacing the temperature control switch, perform simple cleaning or replace consumables according to the instructions in the manual;
Call for Backup
Contact Support: If the above steps don’t resolve the issue, or if you still have questions about what the “E” code means, feel free to contact our support. Our technical support team is always ready to help. We’re here 24/7!
Safety Reminders
Always power down and unplug the autoclave before inspections or repairs.
Never bypass safety interlocks—they’re there to protect you.
