5. Invert mesh rack to provide air space below wraps. End user repair

6. Set bubble level to 4 or 5 o'clock position. End user repair

7. Check for airflow through unit. While the Statim is running in the drying cycle remove exhaust tubing from the top of the waste bottle (be careful tubing may be hot). Place tubing into a cup of water, vigorous bubbles should appear in the cup of water. If air bubbles do not appear check airflow from compressor to waste bottle. End user or Field Service Tech. repair

Before using the Original Statim Error Codes verify that the Statim says Select A Program when turned on. All leaks should be corrected before proceeding with troubleshooting.

Check Cassette #1

The cassette temperature failed to reach 95°C in three minutes.

1. Boiler does not heat up. No power to boiler. Field Service Tech. repair

2. Check thermal fuse. Using an ohmmeter check for continuity between J1-3 & lower terminal on the boiler. If you read less than 1-ohm the thermal fuse is good. If thermal fuse checks good proceed to step 3, if bad replace and check unit for proper operation. Test pump using pump tester. Field Service Tech. repair

3. Check resistance reading between J1-3 & J1-4 should read approx. 11ohms. Field Service Tech. repair

4. Check for line voltage at terminals J1-3 & J1-4 during warm up. If the reading is good proceed to step 5; if bad PCB (Printed Circuit Board) is defective. Shop repair

5. Check for line voltage at boiler terminals. Field Service Tech. repair

Check Cassette #2

The cassette temperature failed to increase from 95 to 100°C within 80 seconds.

1. Unit will normally have a major steam leak from the cassette. If cassette is leaking repair as needed. Replace cassette seal, lid or tray. End user repair

2. If the cassette is not leaking, unit is reading incorrect chamber temperature. A calibration cassette is required to check chamber temperature. Shop repair

Note: The solenoid does not close until the chamber temperature reaches approx. 102°, therefore the solenoid will not cause this error message to appear.

Check Cassette #3

The cassette has failed to pressurize and achieve a temperature of 110°C within 70 seconds of pressurization.

1. Check for visible steam leaks from the cassette. If the cassette is leaking repair as needed. Replace cassette seal, lid or tray. End user repair

2. If no leaks are visible disassemble the solenoid valve and check for debris or the plunger sticking in the plunger tube. Field Service Tech. repair

3. Check for constant power to the solenoid. Measure AC voltage at J1-7 & J1-8, should be zero volts with cassette out of the unit and line voltage with cassette inserted in the unit. Field Service Tech. repair

4. Verify that the check valve and pressure relief valves are not leaking. Field Service Tech. repair

Check Cassette #4

The Cassette has failed to achieve sterilization conditions within 10 minutes of the chamber first reaching 102°C.

1. Refer to explanation for Check Cassette #3. Check Cassette #5

The software causes the pump to activate while between 2 minutes 44 seconds and 2 minutes 24 seconds remaining in the cycle. If a request to pump water occurs outside of 2 minutes 44 seconds Check Cassette #5 occurs.

1. Check pump and boiler. Field Service Tech. repair

2. Check pump using Pump Tester Bottle. Field Service Tech. repair

3. If pump tests weak and is a new style pump, check the pump filters. Field Service Tech. repair

4. If pump is old style, replace the pump. Field Service Tech. repair

5. If the pump tests good, the boiler needs to be replaced. Shop repair

Note: When checking pumps if the pump is louder than normal check the input filter. If the pump sounds normal or quieter than normal check the output filter.

Check Cassette #6

Boiler temperature is more than 5°C higher than the chamber while sterilizing.

1. When the display changes from "pressurization" to "sterilization" does it take longer than 10 seconds for the pressure information (xxxKpa) to appear in the read-out? Replace boiler. Shop repair

Check Cassette #7

Chamber temperature is below the lower limit 130.5°C during the sterilizing phase of the

Unwrapped/Wrapped Cycle or below 117.5°C during the sterilizing phase of the Rubber and Plastics Cycle.

If the cassette can be removed normally after venting:

1. Check for visible steam leaks from the cassette. If the cassette is leaking repair as needed. Replace cassette seal, lid or tray. End user repair

2. If no steam leaks are visible, disassemble the solenoid and check for debris or the plunger sticking in the plunger tube. Field Service Tech. repair

3. Verify that the check valve and pressure relief valves are not leaking. Field Service Tech. repair

If the cassette is hard to remove after venting:

1. Check for kinked or pinched exhaust tubing. End user repair

2. Check for a clogged venturi in the left rear of the cassette tray. Clean as needed. End user repair

3. Solenoid valve is failing to open. Disassemble and check that plunger slides smoothly in plunger tube. Field Service Tech repair

4. Check for power to solenoid. Using a voltmeter check for line voltage at terminals J1-7 & J1-8 with the cassette inserted. If line voltage is present check for a magnetic field above the solenoid coil. The solenoid coil has a bridge rectifier built into it. To check the coil put your meter on the diode checking scale and read the resistance of the coil, then reverse the leads, the resistance should be approximately the same in both directions. Field Service Tech. repair

Check Cassette #8

Chamber temperature is more than 5°C higher than the boiler while sterilizing.

1. Check the exhaust tube for kinks. End user repair

2. Check for a clogged venturi in the cassette. End user repair

3. Check to see if the condenser bottle is full of hot water. End user repair

4. When the cassette changes from "pressurization" to "sterilization" does it take longer than 10 seconds for the pressure information (xxxKpa) to appear in the read-out? Replace boiler. Shop repair

3. Solenoid valve is failing to open. Disassemble and check that plunger slides smoothly in plunger tube. Field Service Tech repair

4. Check for power to solenoid. Using a voltmeter check for line voltage at terminals J1-7 & J1-8 with the cassette inserted. If line voltage is present check for a magnetic field above the solenoid coil. The solenoid coil has a bridge rectifier built into it. To check the coil put your meter on the diode checking scale and read the resistance of the coil, then reverse the leads, the resistance should be approximately the same in both directions.
