Civco Astra TEE
Civco · Model Astra TEE
Washer/Decontaminator High-level disinfection systems for endovaginal, endorectal, and transesophageal (TEE) ultrasound probes. ASTRA offers enhanced capabilities to increase compliance with disinfection guidelines and manufacturer instructions by ensuring the correct use of disinfection consumables; tracking all necessary disinfectant solution and test strip information, and fully removing the need for any manual data logging outside of ASTRA.
Key tips
- ·A failed biological indicator means the entire load is not sterile - no exceptions, regardless of how the cycle printout looks.
- ·Door gasket wear is the most common real cause of a failed vacuum/pressure test - check it before deeper diagnostics.
- ·Water quality directly affects steam-cycle validity - don't ignore scale or mineral buildup.

Error Codes
Extracted directly from this unit's own service manual.
01HLD has not reached fill level
*Turns off Heater Plate Tubing or CPC is not plugged in all the way. If the level of HLD in the bottle is low and you are pumping air instead of HLD, you will get this code. Put a new HLD bottle in.
02HLD has not reached fill level during WILD cycle
*Turns off Heater Plate Tubing or CPC is not plugged in all the way. If the level of HLD in the bottle is low and you are pumping air instead of HLD, you will get this code. Put a new HLD bottle in.
03Rinse water has not reached fill level
Check water filter and connections from water inlet.
10Appropriate bottle temperature not reached within timeout period
Use a warm water bath to warm the HLD prior to placing it into the machine.
11HLD drain timeout
*Turns off Heater Plate This code occurs when the HLD in the disinfection chamber is taking too long to get back into the HLD bottle. Causes: Kinked line, defective valve, or defective pump.
20Unexpected fluid in disinfection chamber
*Turns off Heater Plate This code will occur when the end user turns the device off during a disinfection cycle. The device will pump whatever it is (HLD or water) into the drain. If the end user turns off the power for any reason during a disinfection cycle, upon the beginning of the next cycle, this code will appear. This code only occurs at the beginning of a cycle. The lower float switch (LS-DRN) indicates that something is in the chamber, which triggers the code. If HLD is in there, it will cause them to lose most of the bottle. 70% of the bottle is pushed into the chamber during a disinfection cycle. As a result, a new HLD bottle must be placed into the Astra device.
21LS-O activated
*Turns off Heater Plate Both the HLD float switch (LS-HLD) and Overflow float switch (LS-O) are activated during a cycle.
22HLD Bottle removed unexpectedly
*Turns off Heater Plate This code occurs when the end user removes the HLD bottle when they are not supposed to. The proximity sensor above Sensor Board A (A-HLD) on the main bulkhead detects this. The sensor is plugged into sensor board A (A-HLD).
23Disinfection chamber level dropped
*Turns off Heater Plate The HLD float switch (LS-HLD) is activated during an HLD or water cycle and becomes inactivated during the cycle.
24Disinfection chamber temperature too low
*Turns off Heater Plate This code occurs if bottle temp. is at bare minimum and sits in the chamber long enough to cool down below threshold. It will pump back into the bottle (Don't turn machine off - you will lose HLD).
25Rinse drain timeout
Quad valve (SV5) or drain pump (P-DRAIN) is faulty or tube connections to these components are kinked.
26WILD drain timeout
*Turns off Heater Plate Quad valve (SV4) or HLD pump (P-HLD) or Dual valve (SV2) is faulty or tube connections to these components are kinked.
27LS-HLD on when LS-DRN off (indicates bad CAP100 or connection)
*Turns off Heater Plate Upper float switch (LS-HLD) or Overflow float switch (LS-O) is faulty.
28Probe inserted inappropriately
Defective Sensor B Board or end user error. Probe sensor (CS-1 or CS-2) is activated at the wrong time.
29Probe removed inappropriately
Defective Sensor B board or end user error. If probe sensor (CS-1 or CS-2) is deactivated at the wrong time.
30Chamber door left open during HLD fill
Magnet or door sensor (DS-1) inside top cover is faulty. Sensor connects to Sensor B Board.
31No Pass Fail selected
The user needs training on MRC testing. The MRC testing timed out because no selection was made.
32Upper level sensor failure
*Turns off Heater Plate HLD Sensor does not activate during the HLD or water cycle, indicating that either the sensor is stuck or faulty.
40Both A missing
*Turns off Heater Plate The Main board does not see either of the Sensor A boards. Check the connections. Faulty connections, faulty main board, or faulty Sensor A boards.
41A-DC missing
*Turns off Heater Plate Sensor A Board for the Disinfection Chamber (A-DC) is not plugged in (this is located behind Sensor B board). Selector switch on this board must be set to 0.
42A-HLD missing
Sensor A Board on bulkhead (A-HLD) is not plugged in. Selector switch on this board must be set to 1.
43B missing
Sensor B Board is faulty. 2 switches have the same pin layout – 2 wires with 3 pin connector. If they are plugged into the wrong connector, it will damage the B board and require replacement.
44Display missing
Display board error.
50A-DC Comm error: Timeout
*Turns off Heater Plate Faulty Main Board or A-DC Board. A-DC Board is located behind Sensor B Board near the top of the Astra unit.
51A-DC Comm error: Bad CRC

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Cycle fault / abort
- Note the fault code and the phase it aborted in.
- Check the water fill and drain and clean the chamber filter / strainer.
- Confirm the spray arms rotate freely and the nozzles are clear.
- Verify the heater reaches the disinfection temperature and the sensor agrees with a reference.
- Follow the service manual for the specific code; replace the failed valve / heater / sensor.
Symptom: Instruments come out soiled / spray arms not turning
- Clear the spray-arm nozzles and confirm each arm spins freely.
- Clean the chamber filter / strainer and the drain.
- Confirm detergent and neutraliser are dosing (prime the pumps).
- Check the wash-water pressure and temperature.
- Run a soil / protein-residue test on the next cycle.
Symptom: Chemistry not dosed / dosing-pump alarm
- Confirm the chemistry containers are not empty and the pick-up tubes reach the fluid.
- Prime the dosing pumps and clear any air lock.
- Check the dosing-pump tubing for wear and the level sensors.
- Verify the dosed volume per the service procedure.
- Replace worn peristaltic tubing or the dosing pump.
Symptom: Disinfection temperature (A0) not reached / door-seal leak
- Compare the chamber temperature to an independent reference during the hold.
- Check the heater element draws current and the steam supply (if steam-heated).
- Inspect the door gasket for a leak and the door-lock solenoid.
- Replace the temperature sensor if it disagrees with the reference.
- Re-run and confirm the A0 / hold is met.
