Thermador Range Error Code Er:06

Er:06 indicates that the control board has detected a short-circuit condition in the NTC temperature sensor circuit on the WFR 2460 washer system. The NTC sensor is a thermistor that reports temperature by varying its electrical resistance, and a short-circuit causes it to send an out-of-range low-resistance signal. The range will not operate normally until the fault is resolved by repairing the wiring or replacing the sensor.

No, you should not attempt to operate the range while Er:06 is active. This fault indicates a compromised temperature sensor circuit, which means the appliance cannot accurately monitor temperatures during operation. Continuing to use the range under this condition could result in uncontrolled heating or other unsafe behavior. Resolve the fault before resuming use.

Repair costs vary depending on whether the issue is a wiring repair or a component replacement. NTC sensor parts generally range from modest to moderate in cost, while a service call and labor can add significantly to the total depending on your region and the technician's time required. If the control board is determined to be at fault, costs will be higher. Getting a diagnostic quote from a certified technician before authorizing repairs is advisable.

A knowledgeable DIYer can perform basic diagnostics such as visually inspecting the wiring harness, checking for moisture at connectors, and testing the NTC sensor with a multimeter. If a shorted wire is identified and accessible, it can potentially be repaired. However, if the NTC sensor itself requires replacement or the fault involves internal components, working with an appliance technician is recommended to ensure correct parts and safe reassembly.

A power reset by disconnecting the range from its power source for several minutes may temporarily clear the error display, but Er:06 will return if the underlying short-circuit in the NTC sensor or its wiring has not been corrected. The fault code is generated by an active hardware condition, not a software glitch, so a reset alone is not a fix.
