TROUBLESHOOTING MACHINE ERRORS ERRORS
CATHETER ERROR
ERROR CODES 50, 51, 52, 55, 56, 57 or 58
POSSIBLE REASON
Umbilical cable may be faulty
ACTION Turn power off then on again to clear error message and replace cable. If error persists, replace the catheter.
HOW TO AVOID Keep track of how many times umbilical cable is used. As it nears 20, be prepared for this error.
Make a note of the treatment time.
OVERHEATER ERRORS

If the uterus is anteverted / retroverted, the Turn the machine off then on again. catheter may not be centered in the uterus and instead, pressed against the top or Reposition the catheter so that it is centered in the uterus. bottom of the uterus. Rotate catheter 90 degrees. If there is less than 8cc of fluid in the balloon because of a small uterus, the catheter may Regain a starting pressure between 160 - 180 mmHg. be having difficulty circulating the fluid inside the balloon. Manually terminate the procedure by pressing the stop button when the therapy has reached 8 minutes.
If the uterus is anteverted / retroverted, the doctor should use a tenaculum to straighten the uterus and hold in place. The catheter should be centered in the uterus (not necessarily parallel to the floor). If anteverted, rotate catheter 90 degrees to keep heat sensors in fluid. The physician should hold the catheter centered in the uterus throughout the procedure.
Make a note of the treatment time. During preheat / therapy cycle, heat may cause the uterine pressure to rise. The pressure may fluctuate due to cramping.
OVER PRESSURE ERROR
63
Turn the machine off then on again. Reposition the catheter so that it is centered in the uterus.
If the pressure reaches 200 mmHg, you will Restart using lower starting pressures (160 mmHg). hear a high pressure warning. If the pressure > 205mmHg for more than 2 seconds, the Manually terminate the procedure by pressing the stop procedure will abort. button when the patient has received the remainder of the 8-min therapy.
If pressure goes about 200 mmHg, the doctor may tap the trumpet valve to release some of the pressure. Use NSAIDS pre-op to reduce potential for contractions intra-op. Consider paracervical block even if under general anesthesia. If the uterus is smaller than average, you may need to start at a pressure closer to 160 mmHg.
ERRORS
ERROR CODES
POSSIBLE REASON
If the physician is using more than 35 cc of D5W, the temperature may not reach 87 degrees celsius within 4 minutes.
PREHEAT UNDERTEMPERATURE ERRORS
64
During the preheat, heat may cause the pressure inside the uterus to rise above the 200 mmHg. The heater element inside the balloon will turn off until the pressure drops below 200 mmHg, making the preheat stage last longer.
ACTION
HOW TO AVOID
A large, vascular uterus may not allow for volume of fluid to reach starting temperature. Turn off power then on again to clear error message. If the physician is using large amount of fluid (@ 35 cc), restart and allow machine to preheat the pre-warmed fluid.
If the pressure rises above 195 mmHg, the doctor may tap the trumpet valve to release some of the pressure. This device is not indicated for uteri > 35 cc volume.
If not using a large amount of fluid and the problem persists, swap out umbilical cable and use same catheter. If problem persists, use another catheter.
Check to make sure the D5W was used. If so, it is probably a catheter malfunction.
HEATER OPEN / SHORT ERRORS
65
If D5W was used, then the catheter is Turn power off to clear error message. definitely bad. If saline was accidently used, then it caused the heater to short out. Replace catheter and restart.
Use only D5W!
Manually terminate procedure when patient has received full 8 - minute therapy.
CATHETER ERROR 68
MOTOR FAULT
68
Fluid temperature didn't rise approx 6 degrees celsius within 30 seconds. Umbilical cable may be faulty.
Turn power off then on again to clear error message and replace umbilical cable. If error persists, replace the catheter.
Keep track of how many times umbilical cable is used. As it nears 20, be prepared for this error.

If the turning. 99.9% of the time it is caused by physician wants to regain circulation: Prior to connecting the catherter, ensure that all twists in the pressure line or a faulty catheter. twists are completely removed from the It is almost never a faulty controller. Turn off the controller, straighten the pressure line and pressure line (tugging on the pressure line restart. (You may have to remove the fluid and doesn't help, let the connection end spin freely Inside the clear pressure line is a smaller wire disconnect pressure line from controller to sufficiently get as you work out the twists). Keep the controller that spins, and in turn spins the impeller. If the twists out). a good 3 - 4 feet from the surgeon. the wire cant spin freely, then it will stop turning and cause a motor fault. Manually terminate procedure when patient has received remainder of 8 - minute therapy. E9363
