What Er:17 means on a Thermador range

Er:17 on a Thermador range indicates a pressure sensor failure within the WFR 2460 washer system. The pressure sensor monitors fluid or gas pressure within this subsystem and sends a continuous signal to the control board. When the board detects that the sensor's output is out of range, missing, or inconsistent with expected parameters, it flags Er:17 to alert the technician that the sensing circuit has failed or that the sensor itself is no longer functioning correctly.

The most likely causes fall into two categories: a wiring or connection fault in the line running to the pressure sensor, or a failed sensor component itself. A damaged, pinched, or corroded wire in the sensor circuit can interrupt the signal and trigger the error even if the sensor is physically intact. Corrosion at connectors, loose terminals, or breaks in the harness should be inspected before condemning the sensor.

The diagnostic procedure begins with a thorough inspection of the pressure sensor line, checking for continuity, visible damage, and secure connections at both the sensor and control board ends. If the wiring checks out and no faults are found, the pressure sensor should be replaced. This is a component-level repair and is not resolved by simply resetting the unit, as the underlying hardware fault will persist and the code will return immediately or upon next use.

Common causes of Er:17

  1. 01

    Damaged or broken sensor wiring

    Wiring / connection

    The wire or harness running to the pressure sensor may be pinched, cut, or broken, interrupting the signal to the control board. Inspect the full length of the sensor line for visible damage or loose connections.

  2. 02

    Corroded or loose connector terminals

    Wiring / connection

    Corrosion or a poor connection at the sensor plug or control board terminal can cause an intermittent or absent signal. Check and clean all connectors in the pressure sensor circuit.

  3. 03

    Failed pressure sensor

    Part replacement

    The pressure sensor itself may have failed internally and is no longer producing a valid output signal. If wiring and connections are confirmed good, the sensor requires replacement.

  4. 04

    Control board fault

    Part replacement

    In less common cases, the control board may fail to correctly read a functioning sensor signal due to a board-level defect. This should only be considered after the sensor and wiring have been ruled out.

Frequently asked questions about Er:17

What does Er:17 mean on a Thermador range?
Er:17 indicates a pressure sensor failure in the WFR 2460 washer system of your Thermador range. The control board is not receiving a valid signal from the pressure sensor. This points to either a wiring fault in the sensor line or a failed sensor component. The unit will require inspection and likely a sensor replacement to resolve the error.
Can I fix Er:17 on my Thermador range myself?
A knowledgeable DIYer can begin by visually inspecting the pressure sensor wiring and connectors for damage, corrosion, or loose terminals. However, if the sensor itself needs replacement, identifying the correct part and accessing the component may require disassembly and some technical experience. If you are not comfortable working with internal wiring and components, a qualified appliance technician is recommended.
Will resetting my Thermador range clear the Er:17 code?
Resetting the range will not permanently clear Er:17 because the code is caused by a hardware fault in the pressure sensor circuit. The error will return as soon as the control board checks the sensor signal again. A physical inspection and repair or replacement of the faulty component is required to resolve it.
Is it safe to use my Thermador range while Er:17 is displayed?
Er:17 relates to the pressure sensor in the WFR 2460 washer system, and continuing to operate the appliance with an active sensor fault is not recommended. Operating with a failed monitoring component can prevent the system from detecting abnormal conditions. It is best to have the fault diagnosed and repaired before resuming normal use.
How much does it cost to repair Er:17 on a Thermador range?
Repair costs will vary depending on whether the issue is a wiring fault or a failed sensor. If only a connector or wiring repair is needed, costs are generally lower, typically in the range of $75 to $200 for a service call and labor. If the pressure sensor itself requires replacement, parts and labor combined could range from $150 to $400 or more depending on the specific component and your location.
