How do I fix or replace a Braun Series 7 razor head when parts keep falling out?
Answer
Parts that fall out of a Series 7 head usually mean the cassette is worn, clipped in incorrectly, or due for replacement. Power the razor off, reseat or replace the entire shaver head with the matching Series 7 cassette, and order only the head type printed for your model.
Before you start: stop right away if…
- Do not use a razor with a torn foil or exposed cutter; it can cut skin.
Follow these steps
Power off and remove the head cassette
Turn the razor off. Press the release points for the Series 7 cassette and lift it straight off the handle.
You should see: The head comes off as a unit so you can inspect how the parts should sit.
Inspect and reseat the cutter block
Check whether the foil frame and cutter block are cracked or missing clips. If parts are intact, align them in the cassette until they sit flush and click or lock as designed.
You should see: Parts stay in place when you gently shake the cassette upside down over a towel.
Reattach the cassette and test
Click the cassette back onto the Series 7 handle until it locks, then run the razor briefly away from skin to confirm nothing rattles loose.
You should see: The head stays assembled during a short test run.
Order the correct replacement head if parts will not stay locked
Read the replacement cassette code from the manual or old head packaging and order that Series 7 cassette from Braun or a major retailer. Replace the whole cassette rather than mixing unmatched foils.
You should see: A matching Series 7 head installs firmly and holds together during shaving.

Extra tips
What to look for: Whether the head cassette clicks firmly into place, any cracks on the plastic frame, and the Series 7 replacement code printed in the manual or on the old cassette.
Before you change anything: Turn the razor off and unplug it if it is charging. Work over a towel so small parts are not lost. Match replacement part numbers to Series 7, not Series 5/9. Avoid forcing metal foils that are bent or torn.
