What can you try?

  1. 01

    Record the code and exact appliance model

    Photograph F138 as displayed and record the full model number from its label. Miele may use different meanings for the same characters on other products.

    What the result means: Do not treat a generic code as proof of a failed component.

  2. 02

    Look for a real leak without touching electrics

    If water is on the floor, shut off the accessible water supply without touching wet electrical parts. F138 indicates base-tray water; Miele notes F220 can sometimes appear without an actual leak.

    What the result means: Never restart a leaking appliance; request service.

  3. 03

    Escalate with useful details

    Give support the exact F138 display, full model, when it appeared and safe checks completed. Do not run the unit with smoke, leakage, burning smell or breaker trips.

    What the result means: A service technician must test the suspected component rather than guessing from the code.

Stop immediately for leaks, smoke, burning smell or electrical danger. For gas leaks, leave the area and call local emergency services.

How do you actually fix this?

Start with safe checks. Some codes have no safe home fix; in that case we explain what the professional repair actually involves.

Practical fixes you can try

  1. Stop the cycle and close the water valve. If the floor is wet, do not touch plugs or electrical controls in the wet area.
  2. Visually inspect accessible hoses, tap joints and door seals. Remove trapped laundry or debris only when the appliance is completely safe to handle.
  3. Never tilt the appliance to clear a base-pan leak warning. Do not restart while a leak or overflow is unresolved.

If it persists, how is it actually repaired?

A technician traces the real leak and checks hoses, seals, pump housing, valves or level control. The cause must be fixed and leak-tested rather than merely clearing the warning sensor.

How do you know it is fixed? On controlled testing there should be no new dripping and filling/draining should be normal. Stop at the first leak.

Safety and warranty: Warranty terms depend on manufacturer, model and local law. Damage caused by unauthorised disassembly or improper repair may be excluded. Live electrical work, gas, refrigerant circuits and sealed cabinets require qualified professionals; this is not a DIY instruction for those tasks.

Evidence: The manufacturer link above supports the broad code meaning. The repair pathway is a general technical diagnostic explanation, not a confirmed failed-part diagnosis for every model.
