Thermador Range Error Code Er:10

Er:10 indicates that the WFR 2460 washer motor is not rotating, or that the tachogenerator sensor attached to the motor is not producing a valid speed signal. The tachogenerator provides feedback to the control board confirming that the motor is spinning at the correct speed. When this signal is absent or incorrect, the control board logs Er:10 and interrupts normal operation. A technician should run Test Programme 4 to begin diagnosing the fault.

A power reset may temporarily clear the error code from the display, but it will not resolve the underlying fault. If the motor, tachogenerator, or wiring has a genuine defect, the error will return as soon as the affected function is used again. The fault must be properly diagnosed and repaired to prevent recurrence.

Repair costs vary depending on which component has failed. A wiring or connector repair is typically the least expensive option, often in the range of $75 to $200 including labor. Replacing a tachogenerator or motor assembly can run between $150 and $500 or more, depending on parts pricing and labor rates in your area. A control board replacement, if required, tends to be at the higher end of the cost range.

Some basic checks, such as inspecting wiring connectors for corrosion or loose terminals, can be performed by a knowledgeable DIYer. However, properly diagnosing this error requires running the built-in motor test programme (T/P 4) and performing electrical tests on the tachogenerator and motor windings, which require a multimeter and familiarity with appliance electronics. Replacing the motor or tachogenerator should only be done by a qualified technician to ensure safety and correct reassembly.

It is not advisable to continue using the appliance while Er:10 is active. A motor that is not operating correctly can place additional stress on related components and may indicate an electrical fault. Continued use before the issue is repaired could lead to further damage or create a safety hazard.
