What F4167 means on a Miele washer

The F4167 error code on a Miele washer indicates a power interruption event detected by the ELP 235 module. Specifically, the ELP 235 has registered a break in power supply lasting 100 milliseconds or longer. The ELP 235 is a power monitoring component within the machine's control architecture, responsible for tracking the stability and continuity of incoming electrical power. When it detects a dropout that meets or exceeds the 100 ms threshold, the fault is logged and the error code is triggered.

The most likely source of this fault is an unstable or interrupted power supply external to the washer itself. Brief voltage sags, grid fluctuations, a loose connection at the wall outlet, or a failing circuit breaker can all produce the type of power break the ELP 235 is designed to detect. Extension cords and power strips introduce additional resistance and can cause transient drops that are long enough to register. The washer's internal wiring harness, the power inlet assembly, and the connection between the main supply and the control electronics are also worth inspecting if the external supply appears stable.

Because the ELP 235 is an integral part of the control system, a fault within the module itself or its associated wiring can also produce this code without any actual external power interruption occurring. If the error appears consistently despite a verified stable power supply, the ELP 235 module or its wiring connections should be evaluated. Repeated occurrences of F4167 can disrupt cycle completion and may indicate a broader electrical reliability issue that warrants prompt diagnosis.

Common causes of F4167

  1. 01

    Unstable household power supply

    Wiring / connection

    Voltage sags or brief outages from the home's electrical grid or a loaded circuit can cause a power break long enough to trigger this code. Check whether other appliances on the same circuit are causing load spikes.

  2. 02

    Loose or faulty wall outlet connection

    Wiring / connection

    A loose plug, worn outlet contacts, or a damaged power cord can produce intermittent power drops at the 100 ms threshold. Inspect the outlet and power cord for any signs of looseness, scorching, or damage.

  3. 03

    Failing or tripping circuit breaker

    Wiring / connection

    A circuit breaker that is aging or marginally sized for the load may trip or partially lose contact briefly during washer operation. Test the breaker and confirm the circuit is rated appropriately for the washer's power requirements.

  4. 04

    Internal wiring harness issue

    Wiring / connection

    Loose, corroded, or damaged wiring connections between the power inlet and the ELP 235 module can simulate a power interruption internally. Inspect all harness connectors in the power supply path for secure seating and corrosion.

  5. 05

    Faulty ELP 235 module

    Part replacement

    If the external supply and all wiring are confirmed to be in good condition and the error persists, the ELP 235 module itself may be defective and incorrectly registering power breaks. Replacement of the module would be required in this scenario.

Frequently asked questions about F4167

What does F4167 mean on a Miele washer?
F4167 means the ELP 235 power monitoring module detected a break in the power supply lasting 100 milliseconds or more. The washer logs this fault to alert you to a power reliability problem, which could originate from the home's electrical supply or from a component inside the machine. The error causes the washer to halt its current operation until the issue is addressed.
Can I fix F4167 myself without a technician?
Some causes of F4167 are DIY-friendly. Start by confirming the washer is plugged directly into a dedicated wall outlet and not an extension cord or power strip, and check that the outlet and circuit breaker are functioning properly. If the error continues after ruling out external power issues, the internal wiring or ELP 235 module will need evaluation, which typically requires a qualified technician.
Is it safe to keep using my Miele washer with error code F4167?
It is not advisable to continue running the washer while F4167 is active without investigating the cause. Repeated power interruptions can potentially damage sensitive control electronics over time. If the source is an unstable circuit or loose wiring, there is also a broader electrical safety concern that should be resolved promptly.
Will resetting the washer clear the F4167 error?
Resetting the washer may clear the code temporarily, but the fault will return if the underlying cause has not been corrected. A reset does not address the power interruption that triggered the error in the first place. Use the reset to confirm whether the problem is intermittent or persistent, and continue diagnosing from there.
How much does it cost to repair a Miele washer showing F4167?
If the issue is simply a faulty wall outlet or circuit problem, repair costs may range from around $50 to $200 depending on the electrical work involved. If the ELP 235 module itself needs replacement, parts and labor combined can range from $150 to $400 or more, depending on parts availability and local labor rates. Getting a diagnostic visit from a Miele-authorized technician will give you a more accurate estimate for your specific situation.
