If The Autoclave Skips The FILL Mode

Display/Symptom Cause What to Check Solution
C573: HEATUP MODE
STEAM TEMP OVERLIM
UNPLUG / REPLUG UNIT
ITEMS NOT STERILE

Steam temperature exceeds 284°F (140°C) during Heatup mode		 Tray rack / tray plate not installed properly Inspect tray rack / tray plate for proper installation. (Angled end of tray plate must be toward the back of the chamber) Install tray rack / tray plate properly. Unplug sterilizer for 60 seconds before plugging back in.
Running consecutive cycles without completing the DRY mode Autoclave Should be allowed to complete the Dry Cycle before starting another cycle The sensors must be allowed to dry before initiating another cycle
Water level sensor malfunctioning Check the Water Level Sensor Disc to see if it is damp or wet Dry Water Level Sensor Disc with a Lint Free Cloth and try another cycle
Perform: Water Level Sensor Testing While there is an electrical test you an perform to verify the water level sensor is malfunctioning, there is a more simple & direct way to test it

Remove the Base Tray Plate & Tray Rack from the autoclave. Pour Distilled Water into the chamber until it touches the water level sensor & start another cycle. If it successfully completes the cycle, then you know the Water Level Sensor is bad & needs to be replaced

If The Autoclave Completes The Fill Cycle

Display/Symptom Cause What to Check Solution
C573: HEATUP MODE
STEAM TEMP OVERLIM
UNPLUG / REPLUG UNIT
ITEMS NOT STERILE

Steam temperature exceeds 284°F (140°C) during Heatup mode		 Pressure leaking from chamber Check for pressure leaks. Click Here To See "How To Find Pressure Leaks" Repair or replace malfunctioning component
Temperature sensor malfunctioning Be sure there is nothing touching the temperature sensor. (Example: trays, pouches, cassettes, etc) Reposition items so nothing touches the temperature sensor
Check the temperature sensor probe for corrosion or residue. Clean the temperature sensor with Mid-Clean and distilled water. Click Here to get Mid-Clean (Part #MIC143-6907)
Perform Temperature Sensor Testing Follow instructions in test procedures
Sterilizer is not Level Check surface where autoclave is located to make sure it is level Level with Front Leveling Feet, or move the autoclave to a level surface
Pressure sensor tubing to PC board clogged or restricted Check for blockage in the pressure sensor tubing between the PC board and the chamber. In addition, inspect the filter located inside the chamber to be sure it is not clogged Clear any restriction that could prevent chamber pressure from reaching the pressure sensor on PC board
PC board malfunctioning Perform Pressure Transducer Voltage Test Follow the instructions in test procedures
