What LOCK ON
actually means.
Panel Lock on the Bosch drawer microwave freezes the touch controls and the motorized drawer together, so it will not slide open when a child presses Open. It is switched on and off by holding the number 5 for three seconds, which is easy to do by accident while cleaning.

What to do when LOCK ON shows on the microwaveKind of codeMode, not a failure
Something was switched on rather than something wearing out: a child or control lock set by a long press on the wrong pad, after which no key answers, a demo or showroom setting that lights the display and turns the plate while nothing warms, a Sabbath setting that dims the panel and mutes the beeps, or a clock left blinking after an outage that holds the keypad until it is set. No part is needed; a key sequence from the manual switches it off again.

Touch and hold the number 5 for 3 seconds; LOCK OFF should appear.
Shows up asWhat a Microwave Error Code Is Telling You
A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared.

Before you book,
in this order.
Each step comes from Bosch's own guidance for LOCK ON on its microwaves. Follow it to the end: the last card says whether this is a visit.
Touch and hold the number 5 for 3 seconds; LOCK OFF should appear.
If the lock came on during cleaning, finish wiping first, then unlock.
If LOCK OFF shows but the drawer still ignores Open, book a visit to check the drawer mechanism.
Cleared?
The code has gone and a mug of water heats again without a new part. If it comes back this week, or the food starts coming out cold in the middle, mention in the booking that it came back.
What not to do
LOCK ON does not mean the drawer motor or its gears have failed. It also clears itself after a power interruption, so a lock that returns on its own after an outage was set again by someone.

Microwave drawer
A microwave built under a counter or into a kitchen island that opens like a drawer at the touch of a key, with a motor and gears sliding its cavity out toward you.
