Bosch Dryer Error Code E:1301

E:1301 is a water system error related to the dryer's refresher (steam) feature. It is the 4-digit equivalent of error code E:83. The error indicates that the dryer cannot properly access or deliver water to the refresher system. Start by checking and filling the water container, as an empty reservoir is the most common cause.

A basic reset will not permanently clear E:1301 if the underlying cause has not been addressed. The error will return as soon as the refresher cycle is attempted again without sufficient water supply or with a faulty component. Resolve the water system issue first, then reset the dryer by powering it off and back on.

If the fix is simply filling the water container, there is no cost involved. If a water level sensor needs replacement, parts and labor costs typically range from $80 to $200 depending on your location and service provider. A water pump replacement may cost between $100 and $300 including parts and labor. Getting a diagnostic visit from a certified technician will give you a more accurate estimate.

Begin by filling the refresher water container completely and ensuring it is firmly seated in its housing. Restart the dryer and attempt the refresher cycle again. If the error persists after the container is full and properly installed, inspect the water path for scale or blockages. Persistent errors after these steps may indicate a faulty water level sensor or pump, which would require component-level repair.

The E:1301 error specifically affects the refresher steam function and does not necessarily disable all dryer operation. Standard drying cycles may still be available. However, attempting to run a refresher cycle while this fault is active will be unsuccessful, and ignoring a pump or sensor fault long-term could lead to further issues with the water circuit.
