Bosch Dishwasher Error Code Er:06

Er:06 indicates an NTC thermistor short circuit. The NTC is the temperature sensor that monitors wash water temperature and reports it to the control board. The fault triggers when the sensor circuit reports a near-zero resistance value, which signals either a shorted wiring harness or a failed NTC sensor component. The dishwasher will not complete a cycle until the fault is resolved.

No, you should not attempt to run the dishwasher while Er:06 is active. The control board cannot accurately monitor water temperature with a shorted NTC circuit, which means it cannot properly regulate the heating element. Running the machine in this condition risks overheating the water and potential damage to the appliance.

A reset may temporarily clear the error code from the display, but it will not resolve the underlying fault. As soon as the control board checks the NTC circuit again during a wash cycle, it will detect the short circuit and the Er:06 code will return. The wiring fault must be corrected or the NTC sensor must be replaced to permanently clear this error.

A knowledgeable DIYer can address this fault by inspecting the NTC wiring harness for visible damage and testing the NTC sensor resistance with a multimeter. If the wiring is intact and the sensor tests as shorted, replacing the NTC is a straightforward repair. However, if the fault involves the control board or internal harness routing that is difficult to access, a technician may be more appropriate.

If only the NTC thermistor needs replacement, parts typically cost in the range of $15 to $50 depending on the specific model. If a technician is needed for diagnosis and replacement, total repair costs including labor generally fall in the range of $100 to $200. Wiring harness repairs may vary depending on the extent of the damage.
