Bosch Dryer Error Code E:13

E:13 means the dryer exceeded its maximum allowable drying time without completing the cycle. This fault is triggered when the control board determines the load has not reached the target dryness level within the time limit. The cause can be a damaged heating element, a failed bimetal thermal switch, a faulty heater control circuit, or a load that is too large or too wet for a single cycle.

Resetting the dryer may clear the fault code temporarily, but if an underlying component failure is causing the error, the code will return once the dryer runs another cycle and again fails to heat properly. A reset is a reasonable first step, but you should also inspect the heating circuit and reduce the load size to address the root cause before running another full cycle.

Repair costs vary depending on the cause. If only program selection or load size is the issue, there is no parts cost. Replacing a bimetal thermal switch is typically one of the lower-cost repairs, often ranging from $20 to $80 for the part. A heating element replacement generally runs in the $30 to $120 range for parts. If the heater control circuitry on the main control board is damaged, board replacement can cost $100 to $300 or more. Adding professional labor will increase these estimates.

Yes, in some cases. If the fault was caused by an oversized or overly wet load, you can resolve it by reducing the drum load, ensuring your washing machine completes a full spin cycle before transferring clothes, and selecting the correct drying program. If the issue is a component failure such as a tripped bimetal switch, a damaged heater, or faulty heater control, those parts will need to be inspected and replaced by someone comfortable working with appliance electrical systems.

The E:13 code indicates the dryer has already shut down as a protective measure, so it will not continue operating in a normal cycle with the fault active. You should not attempt to bypass this safety feature. If the bimetal switch has tripped due to overheating, operating the dryer before diagnosing the cause of that overheating could create a fire hazard. Address the fault before resuming normal use.
