Type: Dornbracht thermostatic base element (series-neutral, used among others in VAIA / TARA finishing sets)
Problem
The left mixer tap handle does not come loose, preventing the cartridge from being removed or replaced.
Important to know
This article number concerns a Dornbracht thermostatic base element that is used in multiple series (including VAIA and TARA).
The visible style (handles and finish) determines the series, not the built-in part itself.
Solution
The handle can become stuck firmly due to use and internal locking. Follow the steps below to release it safely:
Step 1 – close handle completely
Turn the left handle clockwise until the stop. This reduces tension on the mechanism.
Step 2 – release handle
Then grip the handle firmly with both hands.
Pull the handle straight forward with a controlled, firm movement. This is also known in practice as a "breaking movement".
Note: this may feel firm, but is the normal disassembly method.
Step 3 – remove cartridge
After removing the handle, the thermostat cartridge can be unscrewed and replaced.
Important
- No damage to the base element will occur if executed correctly
- Do not use tools to pry the handle loose
- Only pull manually and straight forward
- All spare parts already ordered remain usable
