MIELE LOCKED

Miele Washing Machine Error LOCKED: Control Lock Active — PIN Required

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washer's control lock (child lock or technician lock) is active and requires a PIN to unlock. The machine will not respond to program selection or start commands until the correct PIN is entered.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Miele washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Child lock or technician lock was activated — either deliberately or accidentally

Also displayed as Locked. Enter code, LOCKED on some models.

Estimated time for safe first checks: Under 2 min with correct PIN; contact Miele if PIN is unknown.

Step-by-Step DIY Fix Guide

  1. SAFETY: Disconnect power before inspecting this appliance.
  2. The factory default PIN for Miele washers is 1-2-5.
  3. With the machine powered on, use the program selector knob to enter the PIN sequence: turn to 1, then 2, then 5.
  4. If the lock clears, the machine will return to normal operation.
  5. If the display shows 'Wrong code' or the lock persists, the PIN has been changed by a service technician.
  6. Contact Miele service with your machine's serial number to retrieve the current PIN.

If the door warning comes back

  • If the door closes normally but the warning keeps returning, the latch or switch path becomes more likely than a simple alignment issue.
  • Default PIN 1-2-5 does not unlock the machine and the PIN was changed during a previous service visit

What This Error Means

Error LOCKED on your Miele washing machine means: The washer's control lock (child lock or technician lock) is active and requires a PIN to unlock. The machine will not respond to program selection or start commands until the correct PIN is entered. Also displayed as Locked. Enter code on some Miele models. The washer's self-diagnostic system has detected this condition and paused the current cycle.

The most frequent cause is child lock or technician lock was activated — either deliberately or accidentally. Work through the causes and fix steps below in order — most Miele washer errors are resolved without a service call.

Error LOCKED is DIY-safe. No specialist tools are required and the fix typically takes under 30 minutes. Follow all steps in sequence.

The control lock is a security feature, not a fault. The factory default PIN is 1-2-5. Enter it using the program selector to restore normal operation.

Most Likely Cause by Symptom

This display item is often a status or indicator message rather than a true fault.

Likely cause: Child lock or technician lock was activated — either deliberately or accidentally

Check first: SAFETY: Disconnect power before inspecting this appliance.

Common Causes

  • Child lock or technician lock was activated — either deliberately or accidentally
  • PIN was changed by a service technician and the default code was not communicated before handover

What Not to Do

  • Do not attempt to guess PINs repeatedly — some Miele models have a lockout period after multiple incorrect entries

Model and Display Variation Notes

Model-family notes

  • Miele washing machine display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.
  • Some models may display the same fault as Locked. Enter code, LOCKED.

Display and panel differences

  • Some control panels show this issue as Locked. Enter code, LOCKED instead of only LOCKED.
  • Panel wording and whether the code appears with letters, numbers, or a longer variant can differ by model family.

Parts, Tools and Service Options

Manual and model check

Check your exact model and manual before ordering any Miele washing machine parts.

This section stays model-first because exact manual and parts matching matters more than a generic replacement suggestion here.

When Not to Keep Troubleshooting

Default PIN 1-2-5 does not unlock the machine and the PIN was changed during a previous service visit

How to Prevent It Recurring

  • Note the PIN in a safe place if a technician changes it during a service visit — the lock display gives no indication of what the current PIN is

Extra notes

  • This page is based on Miele support material and stays conservative where model-specific guidance may vary.
  • The goal is to help you identify safe first checks before you move into parts, service, or model-specific manual lookup.
