If your autoclave has malfunctioned and is displaying the error code “007” it means that the diagnostics portion of your Midmark M11 has detected a water leak somewhere within its system. And It is most likely to be located in 1 of 3 areas:
- Door Gasket
- Fill Solenoid Valve
- Vent Solenoid Valve
Tip # 1: Door Gasket: First Check The Door Gasket. Is there steam escaping from around it? It’s a good idea to take the gasket off weekly and wash it with a mild soapy water. If you have not replaced it in a while, go ahead and replace it. (Midmark recommends replacing it at least once per year (every 6 months if under heavy usage).
Technical Tip–>The Dam Gasket should Always Be midmark Replaced At The Same Time The Door Gasket Is Replaced
Tip # 2: The Fill Solenoid Valve: Just as it’s name implies, This valve controls the water entering the chamber. When functioning properly, it opens when the unit is in the fill cycle. But it can get stuck in either the open or the closed position.
If you find that no water is entering the chamber, then it is stuck closed. If it continues to allow water to enter after it has reached the fill mark and the dial is switched off the fill mode, then it is stuck open.
A sure sign that the Fill Solenoid Valve is stuck in the open position is when you go to use it and the reservoir is empty. Even though you know it was full the last time you saw it, or you recently filled it.
There will be other evidence of it being stuck open as well, including: water under the autoclave, on the counter or even on the floor.
Tip # 3. The Vent Solenoid Valve. This valve controls the water leaving the chamber and re-entering the water reservoir. Like the Fill Solenoid Valve, ot can be stuck in either the open or closed position.
If It is stuck open, you will hear an excessive “Gurgling” Sound in the bottom of the reservoir during the sterilization cycle. If it is stuck in the closed position, you will notice water in the chamber at the end of the cycle.
