Bosch Washer Error Code E:06

E:06 on a Bosch washer means the NTC temperature sensor has been detected as open-circuited, meaning the control board is receiving no signal from the sensor at all. This is caused by either a faulty NTC thermistor or a break somewhere in the wire harness connecting it to the board. The washer cannot safely control water heating without this sensor, so it halts operation and displays the fault code.

It is not recommended to continue running the washer with an active E:06 fault. Without a functioning temperature sensor, the control board cannot properly monitor or regulate water heating, which creates a risk of overheating the water or running cycles that do not meet the selected temperature settings. Resolve the fault before resuming normal use.

Resetting the washer may temporarily clear the E:06 code from the display, but the fault will return as soon as the control board attempts to read the NTC sensor again and detects the open circuit. A reset does not fix the underlying hardware problem. The NTC sensor or wire harness must be diagnosed and repaired for the error to clear permanently.

Yes, this repair is within reach for a knowledgeable DIYer comfortable with basic electrical testing. Start by running diagnostic test P16 on your Bosch washer, then use a multimeter to check the NTC sensor for continuity and inspect the wire harness for breaks or corrosion. If the sensor tests as open-circuit, it can be replaced. If the harness is damaged, the affected section or connector will need to be repaired or replaced.

If the NTC thermistor needs replacement, the part itself typically costs in the range of $15 to $50 depending on the specific model. If a professional technician is needed, total repair costs including labor generally fall in the $100 to $250 range. A damaged wire harness repair can vary depending on the extent of the damage and whether a full harness or just a connector is involved.
