What to do if Tuttnauer 5075 displays ‘Low Heat’?
If the Tuttnauer Laboratory Equipment displays ‘Low Heat’, make sure the machine has the proper amount of sterilization load and is not overloaded.
What does 'Heat Time Error (Keep)' mean on my Tuttnauer Laboratory Equipment, and how can I fix it?
If your Tuttnauer Laboratory Equipment displays a 'Heat Time Error (Keep)' message, it means the system couldn't reach the required temperature in the chamber during the optional "Keep Heat" stage within the preset time. To resolve this, verify that the autoclave is not overloaded.
What does 'High Pressure (Exhaust)' mean on my Tuttnauer Laboratory Equipment and how do I fix it?
If your Tuttnauer Laboratory Equipment displays a 'High Pressure (Exhaust)' message, it means the system couldn't reach the preset pressure within 10 minutes from the beginning of the exhaust stage. This can be due to the exhaust valve not opening because of a faulty connection or a faulty I.O. board, or the exhaust valve itself might be faulty. First, perform a new cycle. If the problem persists, fix the connection, replace the faulty I.O. board, or replace the faulty valve.
What does High Temp error mean on Tuttnauer 5075 Laboratory Equipment and how to solve it?
The 'High Temp' message on your Tuttnauer Laboratory Equipment is displayed if the temperature rises 7°F (4°C) above the sterilization temperature during the sterilization stage for 2 seconds during sterilization cycle. To solve this, perform a new cycle.
What does High Pressure (Exhaust) error mean on Tuttnauer Laboratory Equipment and how to solve it?
The 'High Pressure (Exhaust)' message on your Tuttnauer Laboratory Equipment means the system couldn't reach the preset pressure within 10 minutes from the start of the exhaust stage. To address this, perform a new cycle.
How to fix RTC Error on Tuttnauer 5075?
Set the current date and time on your Tuttnauer Laboratory Equipment. If the problem continues, call a technician.
What should I do if my Tuttnauer Steriliser displays 'Power Down'?
If the Tuttnauer Steriliser displays 'Power Down', it means a power outage occurred during the cycle. Turn the autoclave back on, wait until it reaches a safe condition, and then perform a new cycle.
What to do if my Tuttnauer Steriliser displays 'Low Pressure'?
If the Tuttnauer Steriliser displays 'Low Pressure', it means the chamber pressure dropped below the sterilization pressure (134°C = 304 kPa, 121°C = 205 kPa) for 2 seconds during the sterilization stage. To solve this, perform a new cycle.
Why is Tuttnauer 5075 leaking at the door?
If the Tuttnauer Laboratory Equipment is leaking at the door, make sure the door is tightened enough. If the leaking continues, replace the door gasket.
What does 'Low Temp' mean on my Tuttnauer Laboratory Equipment and how to fix it?
If your Tuttnauer Laboratory Equipment displays a 'Low Temp' message, it indicates that the temperature dropped below the sterilization temperature for more than 1 second during the sterilization cycle. This can also be caused by a leaking door gasket. Try performing a new cycle. If the issue continues, replace the door gasket.
