Q:  How do we fix the TOMY SX-500 Sterilizer when we get error code E09 (Lid Sensor Defective)?

A:  Most likely it’s the right hook microswitch that is not working properly.  Attached is the process of removing the panel and readjusting the microswitch.

TOMY ES-315 Sterilizer – ERR message – What shall I do?

ERR normally shows a number after indicating the input error (eg. Water level sensor is 1).  Err with no number indicates multiple errors.   If you press start when there is no water in the chamber and the lid is open, you will get an ERR 0 (or ERR according to TOMY).  I have only one case of ERR only and that was related to an external incident that damaged the autoclave severely.  I have never seen this error otherwise (20+ year history).

TOMY changed the circuit board for the new sterilizers around the year 2010, and most likely the ERR without number was added to the logic.

The best course is to make sure the chamber has sufficient water, close the lid and the exhaust valve.  That should isolate the error if there is still one.  If not, they will need to go through the inputs to see which components are failing.  If the inputs test, then the problem is probably with the board.

Thank you,

PriorClave Understands How To Get Things Done Right

This company has been in the autoclave and steam sterilizer business for over two decades and is currently based in London at a 2500 square meter manufacturing facility. PriorClave directs a substantial portion of its profits into continual improvement of their research and manufacturing processes. One of their goals is to bring more of their component creation in-house. Having fewer outside sources involved gives the corporation the ability to reach even higher levels of quality control over every item that goes into their machines.

They currently operate under BS EN ISO9001 requirements with additional oversight of processes and designs provided by Zurich Insurance. PriorClave also makes good use of computer controlled (CNC) equipment to reduce the risk of human error in many of its manufacturing stages.

Safety locks are, of course, standard on all models. These prevent a unit from being opened before the glassware inside is properly cooled (sudden changes in temperature can cause glass to explode). As the icing on the cake, each machine features anti-microbial BioCote on its surfaces to offer continuing decontamination even when the machine is not in use.
