How to fix rusting instruments in Tuttnauer Laboratory Equipment?
- C
  Cheryl HancockSep 12, 2025
  To address rusting instruments from Tuttnauer Laboratory Equipment, first, determine if it's true rust by using a pencil eraser to remove the brown spot. If there is no pitting, the instrument is just dirty. If pitting is present, the rusting may be due to minerals in the water used for rinsing. Use only distilled water for sterilizing and ensure dissimilar metals haven't come into contact.

What causes 'High Pres' to be displayed on Tuttnauer 3545 Laboratory Equipment?
- E
  Eddie ChenAug 23, 2025
  The 'High Pres' message on your Tuttnauer Laboratory Equipment can be due to a few reasons. It could mean the air jet is clogged and needs cleaning. Another possibility is that the heating elements are staying on instead of cycling. A faulty or dirty temperature sensor (PT100) could also be the cause. For the latter two issues, it's best to call a technician.

How to troubleshoot a clogged drain in Tuttnauer Laboratory Equipment?
- J
  Jeremy DawsonAug 25, 2025
  To address a clogged drain in your Tuttnauer Laboratory Equipment, open the drain by turning it counterclockwise. Place a heavy object over the reservoir cover, and blow compressed air into the drain to force debris back into the reservoir, then clean out the reservoir. If needed, disassemble the drain valve by turning it counterclockwise past the stop point, remove the valve, clean it, and blow out the line. Reassemble the valve by turning clockwise, ensuring the large “O” ring is pressed into the groove on the autoclave.

What to do if the POWER indicator light doesn't light up on my Tuttnauer 3545 Laboratory Equipment?
- E
  Elizabeth DavisAug 26, 2025
  If the main switch is in the START position but the POWER indicator light doesn't illuminate on your Tuttnauer Laboratory Equipment, first ensure the equipment is receiving power. Check the circuit breaker and lift the lever if it has tripped. If power is available, the main switch itself may be defective and require checking or replacement. You can test the bulb by setting the timer for 15 minutes and turning the multi-purpose valve to the DRY position; if the HEAT & DRY lights illuminate, the POWER bulb is likely burnt and needs replacement. If none of the lights turn on, there may be a fault in the electrical line, which needs to be checked and repaired from the entry point to the main switch.

Why is the pressure safety valve activated and heating continues in STE position in my Tuttnauer 3545?
- M
  Monica SimsAug 27, 2025
  If your Tuttnauer Laboratory Equipment shows sufficient temperature and pressure, but the pressure safety valve is activated and heating continues while in STE position, it indicates that either the pressure switch (B10) is faulty and not stopping the heating at the required temperature, or the pressure safety valve itself is defective. In either case, the pressure switch (B10) should be fixed or replaced, and the pressure safety valve should be replaced if it's faulty.

What causes the temperature safety device to activate during sterilization cycles in my Tuttnauer 3545 Laboratory Equipment?
- L
  Luis WhiteAug 29, 2025
  If, during sterilization cycles, the temperature safety device is activated due to overheating in your Tuttnauer Laboratory Equipment, it could be due to several reasons. Check if the amount of water in the chamber is insufficient and add water as needed. Also, verify that the thermostat is set to the correct temperature. A leaking multi-purpose valve, which allows water to return to the reservoir, or a leaking safety valve, or excessive leaks from the air trap jet can also cause overheating. Replace these components as necessary.

Why are temperature and pressure insufficient when POWER and HEAT lights are lit in my Tuttnauer 3545?
- J
  Jake DavisDec 1, 2025
  If your Tuttnauer Laboratory Equipment's multi-purpose valve is in the STE position, the POWER and HEAT lights are on, but the temperature and pressure are not sufficient, it could be due to several reasons: 1. The water level might be lower than required, so add water. 2. The pressure switch (B10) might not be calibrated correctly, so calibrate it. 3. Steam could be escaping from the safety valve; try pulling the safety valve ring for 2 seconds, then release; if the leakage continues, replace the valve. 4. The air trap jet hole might be leaking excessively, so replace the air trap jet. 5. Steam could be escaping from the door seal; tighten the door locking bolt, and if leakage persists, replace the door seal. 6. Steam could be escaping from piping connections; locate the leakage an...

What to do if Tuttnauer 3545 is not responding?
- B
  bkempSep 10, 2025
  If your Tuttnauer Laboratory Equipment is not responding, ensure the main switch is in the ‘On’ position and that the power cord is properly connected to both the machine and the mains. Also, check the reset button on the cut-out thermostat and make sure the circuit breaker hasn't tripped by lifting the circuit breaker lever.

What to do if the door handle cannot be turned counter clockwise for opening Tuttnauer 3545 Laboratory Equipment?
- T
  terricarrSep 7, 2025
  If the door handle of your Tuttnauer Laboratory Equipment cannot be turned counter-clockwise to open, it could be due to the door pin being set in the groove. Try slightly turning the handle in the closing direction (clockwise) and then attempt to open it again. If the problem persists, the door locking system may be stuck or the bellows damaged. Consult the “Pressure Door Lock System” section in the service section for further assistance. After opening the door, replace the bellows.
