What F06 means on a Miele dishwasher

The F06 error code on a Miele dishwasher indicates that the flow meter detected too few pulses during the initial water intake phase. The flow meter, also called a water meter or turbine sensor, monitors water entering the machine by generating electrical pulses as water flows through it. During the fill cycle, the control board expects to receive a minimum number of pulses within a set time window. If the pulse count falls short, the board interprets this as insufficient water entering the tub and triggers the F06 fault.

The most common root causes fall into two categories: restricted water supply and flow meter component failure. On the supply side, a kinked inlet hose, a partially closed water shutoff valve, or low household water pressure can all reduce flow below the threshold the control board requires. A clogged inlet screen or a faulty water inlet solenoid valve can similarly restrict or block the flow of water before it even reaches the flow meter.

On the sensor side, the flow meter itself can fail mechanically or electrically. The turbine inside the meter can become jammed by debris or scale buildup, preventing it from spinning and generating pulses even when water is flowing normally. A broken wiring harness connection between the flow meter and the control board can also cause the board to receive no signal at all, mimicking a low-flow condition. Diagnosing F06 typically requires checking water supply conditions first, then inspecting the flow meter for mechanical obstruction or electrical continuity issues.

Common causes of F06

  1. 01

    Low or restricted water supply

    Wiring / connection

    A partially closed shutoff valve under the sink, low household water pressure, or a kinked inlet hose can all reduce the flow rate below what the dishwasher requires. Check that the supply valve is fully open and the inlet hose is not bent or pinched.

  2. 02

    Clogged water inlet screen

    Wiring / connection

    A fine mesh filter screen is located at the water inlet connection on the back of the dishwasher. Mineral deposits and debris can build up and restrict flow enough to trigger F06. The screen can be removed and cleaned with water and a soft brush.

  3. 03

    Faulty or obstructed flow meter

    Part replacement

    The flow meter turbine can become jammed with scale or debris, stopping it from spinning and generating pulses even when water is flowing through it. Inspect the flow meter for obstructions and test it for proper electrical output if the turbine spins freely.

  4. 04

    Defective water inlet valve

    Part replacement

    The solenoid-operated water inlet valve controls water entry into the dishwasher. If the valve is faulty or only partially opening, insufficient water will enter during the fill phase. A failed valve typically requires replacement.

  5. 05

    Wiring or connection fault between flow meter and control board

    Wiring / connection

    A damaged wire, corroded connector, or loose harness between the flow meter and the main control board can prevent pulse signals from reaching the board, causing an F06 error even when the flow meter itself is functional. Inspect the wiring harness for visible damage or loose terminals.

Frequently asked questions about F06

What does F06 mean on a Miele dishwasher?
F06 means the dishwasher detected too few pulses from the flow meter during the start of the water intake phase. The flow meter counts pulses as water passes through it, and if the count is too low, the control board concludes that insufficient water entered the machine. The dishwasher stops the cycle to prevent operating without adequate water. Common causes include low water pressure, a clogged inlet screen, or a faulty flow meter.
Can I fix F06 myself, or do I need a technician?
Some F06 causes are straightforward DIY fixes, such as opening a partially closed water supply valve, straightening a kinked inlet hose, or cleaning a clogged inlet screen. If these steps do not resolve the error, the flow meter or inlet valve may need replacement, which requires basic appliance repair skills and comfort working with water connections and electrical components. If you are not confident with those tasks, a qualified appliance technician is the safer option.
Is it safe to keep using the dishwasher when F06 appears?
You should not attempt to run the dishwasher while the F06 error is active. The machine stops the cycle precisely because it has not confirmed that enough water entered, and running wash and drain components without adequate water can cause motor strain or overheating. Resolve the underlying cause before attempting another cycle.
Will resetting the dishwasher clear the F06 error?
A reset may temporarily clear the fault code, but the error will return at the next fill cycle if the underlying problem is not fixed. Resetting is useful for ruling out a one-time glitch caused by a momentary drop in water pressure, but it is not a repair. If F06 reappears after a reset, systematic diagnosis of the water supply and flow meter is needed.
How much does it cost to repair a Miele dishwasher F06 error?
Repair costs vary widely depending on the cause. Clearing a clogged inlet screen costs nothing beyond your time. Replacing a water inlet valve or flow meter typically involves part costs in the range of $30 to $120 for the components, plus labor if a technician is hired. A professional service call for a Miele dishwasher commonly runs $100 to $250 or more depending on your location and the extent of the repair.
