Error code F86
Appliance Dishwasher
Quick answer

Fault F86 points to an unclosed salt reservoir flap in the door.

Model compatibility

Miele reuses codes across series and model years, so F86 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Salt reservoir flap in the door is not closed.

Why F86 appears

The door carries a flap over the salt reservoir. When that flap stands open, the display reports F86.

At a glance

Code F86
What it means Salt reservoir flap in the door is not closed.
What you can check Close the salt reservoir flap in the door firmly. If it opened during a cycle, turn the machine off and back on, then run the program once more.
When to call a technician If F86 persists after the flap is shut, book a service visit or a repair online.

What the owner does

Shut the flap. Should the fault persist afterwards, Miele advises calling its customer service or booking a repair online.

If it opened mid-program

Miele describes the same fault on its support page as the message “Close salt reservoir lid”: the lid is not shut firmly. Should it have come open during a cycle, turn the machine off and back on using the I sensor, then run the program once more.

Compare

Unlike F87, a technical fault, F86 has a simple owner action. F88 concerns the turbidity sensor.
