My 5-year-old Össur Cold Therapy machine (B0040OFASO) is not working; what troubleshooting steps can I take?

Since your Össur Cold Therapy machine (B0040OFASO) is not working, here are some troubleshooting steps from the manual you can take: Unit does not turn on: Ensure the power cord is securely plugged in, check the power outlet with another device, and verify the power switch is in the 'ON' position. No water flow or weak flow: Add more water to the reservoir, check the tubing for kinks, lift and lower the therapy pad to help release air, and clean the system if mineral buildup is suspected. Water is not cold enough: Add more ice or replace melted ice, ensure the proper water-to-ice ratio, and consider using frozen water bottles for longer-lasting cold. Leaking from connections: Ensure all tubing and pad connections are securely fastened, and inspect O-rings for damage, replacing them if necessary. Given the machine is 5 years old, it's possible that some components may have worn out or accumulated mineral buildup over time. If these steps do not resolve the issue, you may need to contact Össur customer support for further assistance or to inquire about replacement parts, as the limited warranty typically covers only 6 months from the initial purchase.

Monitor skin condition frequently during treatment.

Setup Instructions

Prepare the Unit: Place the Cold Rush unit on a stable, level surface.
Add Water and Ice: Open the lid and fill the reservoir with cold water up to the indicated fill line. Then, add ice. Using frozen water bottles instead of loose ice can help maintain colder temperatures for longer and simplify cleaning.

Connect Therapy Pad: Attach the desired therapy pad (sold separately) to the insulated tubing connectors. Ensure a secure connection to prevent leaks.
Position Therapy Pad: Place the therapy pad on the affected body part. Use the provided straps or wraps to secure the pad in place, ensuring comfortable contact with the skin. A protective barrier (e.g., a thin cloth) between the pad and skin is recommended.
Power On: Connect the power adapter to the unit and then plug it into a standard electrical outlet. Turn the unit on using the power switch.

Operating Instructions

Once the unit is set up, it will begin circulating cold water through the therapy pad. The flow control knob allows for adjustment of the water flow rate.

Treatment Duration: Follow your healthcare professional's recommendations for treatment duration. General cold therapy unit safety precautions suggest treatment durations of up to 6 hours.
Flow Control: Adjust the flow control knob to achieve a comfortable and effective cold sensation. Higher settings increase water flow.
Monitoring: Regularly check the skin under the therapy pad for any signs of irritation, excessive cold, or discoloration.

Maintenance

Cleaning: After each use, empty the water and ice from the reservoir. Clean the reservoir and tubing with mild soap and water. Rinse thoroughly.
Drying: Allow all components to air dry completely before storage to prevent mold or mildew growth.
Storage: Store the unit in a cool, dry place. If storing for an extended period, consider flushing the system with distilled water before storage to prevent mineral buildup in the pump.
