You can be rinsing your 5 head blades just as we instruct, but still have a clog. It's helpful to perform a deep clean on your blades once a week.
All you need is warm water and a drop or two of mild dish soap, something similar to Dawn. Keeping your blade attached to your handle, let the blade sit in that warm water/soap solution for 10 minutes.
From there, turn on your shaver and let it run for 10 minutes. This will expose the clog and get your blades back up to running normally.
