Code L2
medium severity
Miele models: Miele heat-pump and condenser dryers do not vent externally; condensate drains to a collection tank or a direct-drain connection. The door-opening lint filter is the primary filter, but there is a secondary condenser fluff filter in the lower plinth that must be cleaned monthly. A full condensate tank will pause the cycle without an explicit error.
Common causes
- One pole of the double-pole circuit breaker tripped without the other
- Loose wire at the terminal block or breaker
Step-by-step fix
- Reset both poles of the double-pole breaker.
- If heat still fails, have an electrician check the terminal block wiring.
Tools you may need
None (breaker reset); multimeter (if testing voltage)
Prevention
- Have dryer wiring inspected if you experience repeated L2 codes without a clear power event.
When to stop DIY
Call an electrician for all 240V wiring work beyond a breaker reset.
