Miele Dishwasher F600 Error: Clean AutoDos Safely

What F600 Means and Why It Happens

Miele defines F600 as an AutoDos dispensing-process outlet fault and states that the AutoDos system is blocked. When the dishwasher detects it, the running program is canceled and the drain pump starts. That pump activity is a response to the detected fault; it does not turn F600 into a drain-pump or drain-clog code.

The blockage can be visible, but it does not have to look like a completely packed dispenser. The useful question is where the dry detergent path or its flushing process stopped working.

• Powder residue or clumps in the accessible AutoDos path: Dry detergent can accumulate around the user-removable housing, holder, outlet, or the removable fill channel used on AutoDos 1.0. This is the most direct match to Miele's blocked-system explanation.
• Moisture in the dry dispensing area: Damp parts or moisture introduced during cleaning can make detergent powder cake together. Reinstalling parts before they are completely dry can recreate the restriction.
• Incorrect seating after a PowerDisk change or cleaning: A holder that is not flat, a PowerDisk that is not flush, dirty seals, a lid that is not tightly closed, or a handle that is not in the locked position can leave the dispensing path incorrectly assembled.
• Lower spray arm does not flush the outlet correctly: Miele ties lower-spray-arm obstruction and clogged nozzles to incomplete flushing of the AutoDos detergent outlet. A blocked rack path, debris in the nozzles, incorrect arm installation, or a filter combination that is not flat can contribute.
• The owner-accessible path is clear but the fault remains: This does not prove a particular motor, sensor, switch, wiring harness, or control board has failed. It means the exact-model dispensing sequence needs service-level proof after the accessible blockage, seating, and flushing checks have been completed.

Visible dirt therefore supports the F600 diagnosis, but “it is always just dirt” is too strong. Correct cleaning is a meaningful first repair step; recurrence is a different diagnostic state.

F600 Versus F601, F607, and AutoDos Messages

Preserve the exact characters on the display before clearing anything.

• F600: Miele identifies an AutoDos dispensing-outlet fault and blocked AutoDos system.
• F601: A separate generic AutoDos fault. Its instructions include their own holder and PowerDisk checks and may allow AutoDos to be switched off on some models. That fallback is not a guaranteed F600 workaround.
• F607: A separate lower-spray-arm code. Miele associates it with a blocked arm or clogged nozzles that keep the AutoDos outlet from being fully flushed.
• Clean AutoDos: A maintenance message. It can point to residue that needs attention, but the message is not automatically F600.
• Problem with AutoDos: A broader message whose exact-model wording and operating instructions control the next step.
• No AutoDos or no PowerDisk: Do not apply these F600 instructions to a non-AutoDos detergent dispenser or to a generic detergent-release symptom.

Before You Clean AutoDos

1) Photograph F600 before turning the dishwasher off. Also photograph the model and serial label at the door area if it is safely visible.

2) Note when F600 appeared: immediately after Start, during dispensing, after a PowerDisk replacement, after AutoDos cleaning, or after a period of non-use.

3) Turn the dishwasher off before removing the lower spray arm or any owner-removable AutoDos part.

4) Compare the dispenser geometry with the exact model instructions. Miele publishes different cleaning procedures for AutoDos 1.0 and AutoDos 2.0.

5) Keep water and liquid cleaner out of the installed AutoDos housing. Use water only on a removed part when the exact Miele instructions permit it, and dry that part completely before it goes back.

Do not use liquid dishwasher detergent, a chemical drain cleaner, compressed air, a hair dryer, or a heat gun inside AutoDos. Do not force a part that does not release exactly as the operating instructions show.

Choose the Right AutoDos Cleaning Path

• AutoDos 1.0: Miele's F600 instructions include a removable fill channel. Remove and clean it only when the part and release method match the Miele AutoDos 1.0 illustration for the dishwasher. Do not pry it out.
• AutoDos 2.0: Miele gives different housing and holder cleaning instructions. Do not imitate the AutoDos 1.0 fill-channel removal on a 2.0 dispenser.
• Generation is unclear: Stop at the PowerDisk, visible holder, seals, lid, and lower spray arm. Use the exact model number to find the matching operating instructions before removing another piece.

This split matters because “clean AutoDos” is not one universal disassembly procedure. A correct 1.0 step can become a broken-part risk on different geometry.

How to Clean the Lower Spray Arm

1) With the dishwasher off, remove the lower basket.

2) Remove the lower spray arm only by the method shown in the exact operating instructions.

3) Look for accessible particles or debris in the spray openings. Clear only accessible debris and rinse the removed arm thoroughly.

4) Check the filter combination below the arm. It must be correctly installed, locked, and lying flat before the spray arm goes back.

5) Reinstall the lower spray arm and rotate it by hand. It should move freely without touching a rack, utensil, pan, or filter part.

Do not run the dishwasher without the filters and spray arms correctly installed. If the exact display is F607 instead of F600, use the F607 instructions rather than treating the codes as interchangeable.

How to Clean and Reseat AutoDos Safely

1) Open the AutoDos lid and remove the PowerDisk.

2) Inspect the PowerDisk, holder, visible housing, and generation-appropriate removable part for dry powder residue or clumps.

3) Lift out only the holder and any other part that Miele identifies as owner-removable for that exact AutoDos generation.

4) Wipe the installed housing and holder with a lightly damp cloth where Miele permits. Do not pour, spray, or flush water into the installed AutoDos cavity.

5) On AutoDos 1.0 only, clean the removed fill channel with water and a soft brush when it matches the official illustration. Do not perform this removal on AutoDos 2.0.

6) Remove loosened detergent residue from the permitted parts. Avoid scraping sealing surfaces or forcing the dispensing mechanism.

7) Dry the housing surfaces, holder, and every removed part completely. No moisture should remain where dry detergent travels.

8) Reinstall the holder so its arrows align and it lies flat.

9) Install a full PowerDisk so it sits flush in the holder.

10) Wipe the lid seals clean, close the lid tightly, and move the handle fully under the lock symbol.

11) Recheck that the lower spray arm is installed and can rotate freely.

After correct reassembly, turn the dishwasher on and observe one bounded restart. Miele says the dishwasher checks whether the fault is still present. If F600 remains or restart is prevented, the result is evidence for service; it is not a reason to repeat resets or dismantle the dispenser.

How to Help Prevent F600

• Inspect AutoDos whenever the PowerDisk is replaced: Miele operating instructions call for checking the dispensing area at each replacement and cleaning it when residue is present.
• Keep the powder path dry: Do not put fluid into AutoDos. After permitted cleaning, let every removed part dry completely before installing the PowerDisk.
• Seat the PowerDisk and holder deliberately: Align the holder, keep it flat, insert a full PowerDisk flush, keep the seals clean, and lock the lid completely.
• Keep the lower spray arm clear: Load tall plates, pans, and utensils so they cannot stop the arm. Check that it rotates freely after loading.
• Inspect spray openings on the exact model's schedule: One checked Miele manual recommends inspecting spray arms approximately every two to four months. Treat that as a model-manual example, not a universal interval; the dishwasher's own operating instructions control.
• Respond to residue before a fault appears: Clean accessible dry powder when the dishwasher displays Clean AutoDos or when residue is found during a PowerDisk change. Do not wait until the outlet is packed.
• Do not improvise a refill or cleaner: Follow the detergent and PowerDisk instructions for the exact model. Liquid or moisture in a dry powder path can create the clumping the maintenance is meant to prevent.

If F600 Does Not Clear

Stop the homeowner cleaning loop when F600 remains, returns, or prevents restart after one complete, generation-appropriate lower-spray-arm and AutoDos clean, dry, and reseat procedure.

At that point, do not open the door panel, remove the dispenser drive, force a cam or gear, enter service mode, clear fault memory, probe wiring, test live voltage, or order a guessed AutoDos motor. Those steps can erase useful evidence or damage a mechanism that has not been proved faulty.

Do not assume the dishwasher can continue with manual detergent. Miele publishes an AutoDos-off/manual-compartment option in its F601 guidance for applicable models, but the exact F600 page does not promise that bypass, and persistent F600 may prevent the dishwasher from restarting. The exact model and its controls decide what is available.

Before arranging dishwasher diagnosis, record:

• Machine identity: Full model and serial number.
• Exact display and timing: A clear photo of F600 and when it appears.
• Restart state: Whether the program cancels, the drain pump starts, or the dishwasher refuses to restart.
• Maintenance result: Which model-directed lower-spray-arm and AutoDos procedure was completed and whether F600 changed afterward.

What Diagnosis Must Confirm

A useful service diagnosis starts with the documented exact model and the result of the completed owner procedure. It must then prove the hidden failed stage instead of translating F600 directly into a replacement part.

• Commanded movement: Confirm whether the exact-model AutoDos mechanism receives the command and completes its intended movement.
• Mechanical binding: Determine whether the mechanism binds or an obstruction remains beyond owner access.
• Position or feedback state: Prove whether the mechanism's actual position agrees with the feedback expected by the exact model.
• Electrical and control confirmation: Use service information to verify the relevant wiring and control decision only after mechanical conditions are separated.
• Repair decision: Name a part only when a failed mechanical or electrical stage is measured or reproduced. F600 alone is not that proof.
