Concentrate Flow was exceeding the maximum 19.9 bar set point. The standard default set point range is between 4 and 18.Error message (F020104, "concentrate pressure alarm limit exceeded") concentrate pressure is too high and stops the dialysis water supply.

An observed trend of high conductivity dialysate alarms in a hemodialysis system as a result of introducing a software tool into the manufacturing process.

Internal ethemet cables are missing one or both ferrite cores therefore the electromagnetic compatibility of the device is not ensured

Internal ethernet cable may be misaligned, the cable jacket (insulation) could become compromised due to high temperature and result in the internal ethernet cable conducting electrical current to the ethernet port on the outside of the device), potentially harming service technicians and/or other authorized operators. If the ethernet port on the device is touched or manipulated, there is a risk of electrical shock

AquaBplus HF module on the AquaBplus 2000 osmosis system, an error in the US Installation Guideline instructed that 3-ring mains, instead of 2-ring mains, may be installed in combination with an AquaBplus 2000 device. The 3-ring main and fluid fly loops the heat disinfection may not be as effective as a 2-ring main installation

Incorrectly crimped connectors were installed on the main protective earth conductor on these machines. If the machine is moved or maintenance is performed, these crimp connections could become loose and may adversely affect the electrical safety of the products, potentially resulting in electrical shock to the Biomed Technician or clinic staff.

Mar Cor Purification manufactured Central Water Plant (CWP) reverse osmosis system, models 102, 104 and 106. This correction has been initiated due to a potential situation with a specific lot of the water inlet solenoid valve. The potential exists that the water inlet solenoid valve could cease to function. If this occurs, CWP will stop producing reverse osmosis water.

High inlet water pressure beyond specification and the solenoid valve does not meet application which could result in a delay in treatment.

The firm was notified that a malfunction of the device was caused by an incorrect fuse 32 volt 15 amp fuses instead of 250 volt 15 amp fuses, that was installed in the water system. The incorrect fuse may result in excessive heat in the fuse holder eventually resulting in failure of the device to operate.

There exists a potential situation with the crimp connection at the pump head assembly. The potential exists that the reverse osmosis pump head wiring could build resistance resulting in resistive heating of the surrounding components. If this occurs, the pump head assembly may experience melting of the plastic components and potentially create smoke/fire and shut down of the unit.
