Usage Tips: 1. A graphite impeller within the vacuum pump may fail, leading to vehicle performance issues. 2. Water ingress can affect pump operation; over time, the impeller on the motor spindle may break or become damaged. 3. A damaged impeller can result in reduced air pressure or vacuum, impairing the function of the PSE pump. 4. This may also cause motor seizure, potentially leading to a blown 20A fuse and pump shutdown.
