Question 1

Why does the BUFFALO S007 oven turn off before reaching the set temperature?

Accepted Answer

The premature shutdown of the BUFFALO S007 is generally due to the thermal circuit breaker, a protection system that automatically stops the device in case of overheating.

Checks to perform:

Reset the thermal circuit breaker - It is located under the device, between the rear legs. Press the small reset button to reset the device. This is the most common cause.
Check the water level - Never let the water level drop below the MIN mark. An insufficient level damages the heating element and triggers the thermal protection. Regularly top up with water.
Check ventilation - Ensure that the device is not suffocated. It should be in a well-ventilated area, away from walls or obstacles that would block air circulation.
Installation - Place the S007 on a flat and stable surface. Incorrect positioning causes uneven heat distribution and premature shutdowns.
Power supply - The device operates on 230V 50Hz, 5.5A. Check that your power outlet can support this power and that the cable is not damaged.

Recommended procedure: Turn off the device, unplug it, wait 10 minutes for it to cool down, then press the reset button under the rear legs before plugging it back in.

Question 2

Why does the circuit breaker of my meter trip before the BUFFALO S047 reaches temperature?

Accepted Answer

First, check the built-in thermal circuit breaker of the BUFFALO S047: this device is equipped with a safety thermal circuit breaker that may be triggered. If this is the one that trips, refer to the section "Resetting the thermal circuit breaker" in your manual to reset it properly.

If it is your home electrical meter that trips, it is an electrical overload. The S047 consumes 1300W (5.5A) during heating - a significant power:

Plug it in alone to a socket: do not share it on a power strip or an already loaded circuit (oven, radiator, other high-power device).
Check the amperage of your meter (on your EDF bill or contract): if you are at 6A or 9A, the S047 may cause an overload, especially at startup when the heating is at maximum.
Turn off other devices in the house while heating the bain-marie (washing machine, oven, etc.).
Increase the amperage of the meter: if you need to use several devices together, contact your electricity supplier to switch to 12A or 15A.

Once the S047 reaches the holding temperature, the consumption naturally decreases and the risk of tripping decreases.

Question 3

How to format a BUFFALO HD-PXT external hard drive if I have lost the security password?

Accepted Answer

The BUFFALO HD-PXT hard drive is protected by AES 256-bit hardware encryption, which makes the data inaccessible without the correct password. It is not possible to bypass this security to access or recover the data. However, there is an official solution to reset the drive if you have lost your password: a factory reset.

Important: This procedure completely erases the drive and all files it contains. It does not recover your data but allows you to reuse the drive. You will need a Windows computer to perform this operation (Mac OS is not supported).

Steps to reset your HD-PXT:

Connect the BUFFALO HD-PXT drive to a Windows computer
Close any password verification or autoplay windows that appear
Access the menu: Start → Programs → BUFFALO → Secure Lock Manager Easy → Secure Lock Manager Easy
In the software interface, select the reset to factory defaults option
Confirm the action. This operation will erase all data and reset the password

After the reset, the drive will be formatted to FAT32. If you need to store files larger than 4 GB, you will need to reformat the drive to NTFS after the reset. On Mac, you can also use the Mac OS extended file system.

If the Secure Lock Manager Easy software is not installed on your computer, you can download it from the BUFFALO website or retrieve it from the installation CD provided with the drive. Without this reset, there is no way to access or reuse the drive without the original password.
