Midmark M11 & M9 Error Codes
Midmark Error: E001
Error code E001 is a power interruption error. It is possible the unit is plugged into a faulty outlet, make sure that the unit is not plugged into a G.F.I. If the outlet you are plugged into is good it is possible you have a power failure at some point, try running a cycle. If the unit is giving you an E001 during or right after running a cycle it is an indication that the unit is overheating, in which case you will need to get the unit serviced.
Midmark Error: E002
Error code E002 is an indication that the stop button got pressed during a cycle. Make sure none of your staff touches the stop button during a cycle. If you are getting an E002 with nothing touching the stop button it is possible you have a faulty display board that may need replacing.
Midmark Error: E003
Error code E003 is an indication that the On/Standby got pressed during a cycle. Make sure none of your staff touches the On/Standby button during a cycle. If you are getting an E003 with nothing touching the On/Standby button it is possible you have a faulty display board that may need replacing.
Midmark Error: E004
Error code E004 is an indication that the door is ajar during the cycle. Make sure the door is fully closed and the door latch is pushed all the way down so that the door pin engages the door switch. After ensuring that the door is fully closed and latched and E004 is still happening it is possible you have a faulty door switch or the mechanism that engages it need realigned, send it in for service so that this problem can be repaired.
Midmark Error: E005
Error E005 indicates that the pressure exceeded 35 PSI during the cycle. Make sure the sterilizer is not overloaded and try running another cycle. If the Error E005 persists, it is possible you have a faulty steam trap, air bellows or out of calibration and the unit will need to be sent in for service.
Midmark Error: E006
Error E006 happens when the internal temperature exceeds 277 during the cycle. Make sure the unit is not getting overloaded. If you continue to experience the error after running additional cycles it is likely the unit is out of calibration, has a faulty temperature sensor and will need to be sent in for service.
Midmark Error: E007
Error E007 is an indication that there is low pressure during the cycle. The unit is likely losing steam, try checking the unit’s door gasket to make sure that it is not leaking steam and replace it if this is the case. Most of the time this error is caused by an internal steam leak like a backfill or vent valve, the steam trap of bellows or the unit needs to be recalibrated.
Midmark Error: E008
Error E008 means the door did not open at the end of the cycle. The good news is that your instruments likely got sterilized however the error occurred at the end of the sterilization cycle preventing it from going into the dry cycle. This error is more common with older units after years of wear the door pins and latch mechanism wear out and deform causing this to be an ongoing problem. There are a few fixes your repair specialist should be able to try, but if the problem continues perhaps it is time for a new unit.
Midmark Error: E009
Error E009 indicates that there is pressure buildup during the dry cycle. The good news is that your instruments likely got sterilized however the dry cycle did not complete. It is possible that your units 0 calibration is off, or the door is not fully opening at the end of the cycle due to broken door springs or a faulty door mechanism. You would like to need a service specialist to take a look at this issue for you.
Midmark Errors: E010, E011 & E012
Error E010, E011 & E012 are all software issues. Try rebooting the machine by unplugging it for 30 seconds. If this does not work, you likely need a new PC board which will have to be replaced and re-calibrated by a service professional.
