Bosch Dryer Error Code E:167

E:167 indicates a fault in the main heating circuit due to restricted airflow, specifically from a blocked lint filter or a frozen evaporator (heat exchanger). The dryer's control system detects abnormal heating conditions and stops the cycle to prevent damage. Cleaning the lint filter is always the first step, and if the evaporator is frozen, the unit needs time to fully defrost before restarting.

No, you should not continue running the dryer while E:167 is active. The error indicates the heating circuit is not operating correctly due to restricted airflow, and continuing to use the dryer in this condition could cause thermal components to overheat or sustain damage. Address the underlying cause before resuming normal operation.

If the fix is simply cleaning the lint filter, there is no parts cost involved. If the evaporator has frozen due to an ambient temperature issue, the repair is also free once the unit thaws. However, if a refrigerant circuit fault or a failed component is responsible, professional repair costs can range from roughly $150 to $400 or more depending on the specific part and labor rates in your area.

Start by removing and thoroughly cleaning the lint filter, including the filter housing. If the filter is clean, the evaporator may be frozen, and you should unplug the dryer and allow it to sit at room temperature for several hours to defrost completely. After addressing either issue, restart the dryer to see if the error clears. If the code returns repeatedly, a technician should inspect the heat pump refrigerant circuit.

A power reset may temporarily clear the display, but the E:167 code will return if the root cause has not been resolved. You must clean the lint filter or allow the frozen evaporator to fully thaw before the error will stay cleared. Repeatedly resetting without fixing the underlying issue can lead to component damage over time.
