Book a visit

Three short steps, about a minute.

or call (844) 252-4077

Before you book,
in this order.

Each step comes from Miele's own guidance for L on its cooktops. Follow it to the end: the last card says whether this is a visit.

01

Turn the right knob counterclockwise as far as it goes and hold it until L goes out.

02

Make sure the right knob is held all the way counterclockwise, not just part of the way.

03

If L stays after holding the knob, book a visit.

Cleared?

The cooktop came right without a new part. If the same message returns while a zone or burner is on, or the top shuts itself down again mid-meal, treat it as a fresh problem and book it.

What not to do

L is not a failure; the cooktop is locked on purpose. It does not mean a knob or the display is broken.

What you may
notice with it.

The cooktop problems L tends to arrive with. Answer these at the cooktop before anyone is booked.

All problems

No repair indicated

Nothing to repair.

A state the cooktop was put in, or one it picked deliberately — a child lock, a demo mode that lights the keys but heats nothing, a residual-heat letter over a zone that is still warm, a prompt that no pan has been found. Nothing has broken and no part is called for.

In Miele's own words

The system lock is activated.

Questions
about L.

Can I clear L myself?
Turn the right knob counterclockwise as far as it goes and hold it until L goes out.
How do I unlock a Miele cooktop showing L?
Hold the right knob fully counterclockwise until L disappears.
Why would L appear by itself?
The lock can be switched on by a knob sequence during cleaning or by a child.
Why does my Miele knob cooktop show L and not LC or LOC?
Miele uses L for the system lock on its knob-controlled cooktops. LC and LOC appear on other Miele models for the system or safety lock. All of them mean the cooktop is locked on purpose.

Back to your everyday

Still showing L?

Book with the code copied exactly, the full model number, and whether there is any smell of gas or burning — with a code in hand, that is where the diagnosis starts.
