What to do if my Buffalo filter Medical Equipment ViroVac© Surgical Smoke Evacuator does not function?

  If your ViroVac© Surgical Smoke Evacuator Medical Equipment isn't working even when the On/Standby button is pressed, and there are no lights, first, check if it's properly plugged into a grounded electrical outlet and the power receptacle at the back of the device. If that's not the issue, the fuse(s) might be blown. Disconnect the power, remove the fascia and body, and check the two fuses on the circuit board (PCB). Replace them if necessary. It could also mean the filter life has expired or an invalid filter is installed, so try replacing the filter. As a last resort, apply the power directly to the motor. If the motor spins, the PCB is not functioning, then replace the PCB and perform a hipot test and current leakage test.

  If the ViroVac© Surgical Smoke Evacuator Medical Equipment is on but has minimal or no suction, the filter might not be correctly installed. Reinstall the filter, pressing it firmly into place. Alternatively, the filter could be clogged, in which case you should replace it with a new one from the manufacturer. Another possibility is that the vacuum tubing is clogged, so replace it with the manufacturer’s products.

What causes the motor to stop spinning in Buffalo filter ViroVac VV120?

  If the motor in your Buffalo filter Medical Equipment is not spinning, the fuse(s) might be blown. To fix this, disconnect the power, remove the fascia and the body, and then check the two fuses on the circuit board (PCB). Replace the fuse(s) if needed. If that's not the problem, the PCB might not be working. You can test this by applying power directly to the motor; if it spins, the PCB needs to be replaced. After replacing the PCB or motor, perform a hipot test and current leakage test. The motor itself might also be faulty, so if applying power directly doesn't make it spin, replace the motor and perform a hipot test.

  If the buttons on the control panel of your Buffalo filter Medical Equipment aren't working, it could be due to blown fuse(s). Disconnect the power, remove the fascia and the body, and check the two fuses on the circuit board (PCB). Replace them if necessary. Another possibility is that the key pad isn't firmly connected. Once the fascia is removed, check if the key pad is plugged in and fully seated. If it is, try replacing the key pad. If the problem persists, the PCB might not be functioning. Apply the power directly to the motor. If the motor spins, the PCB is not functioning, then replace the PCB and perform a hipot test and current leakage test.

What to do if Buffalo filter Medical Equipment is not recognizing the filter?

  If the filter is not being recognized by your Buffalo filter Medical Equipment, it might have reached the end of its useful life; try replacing it. If a new filter doesn't solve the issue, disconnect the power, remove the cover, and inspect the antenna connection. Unplug the antenna from the PCB and check the connector and wires. If there's any sign of a bad crimp, replace the antenna. If the issue continues, replace the antenna again. As a last resort, apply the power directly to the motor. If the motor spins, the PCB is not functioning, then replace the PCB and perform a hipot test and current leakage test.
