Bosch Dryer Error Code E:3

E:3 on a Bosch dryer means the condensate tank is full or the base group condensate system has detected a malfunction. Bosch condenser dryers collect moisture removed from laundry into a tank or base reservoir, and this code appears when that system cannot function properly. The error stops the dryer to prevent overflow or water damage.

A reset alone will not permanently clear E:3 if the underlying cause has not been addressed. The error will return as soon as the dryer attempts to run and detects the same full tank or base group fault condition. You need to empty the tank, clean the electrodes, and confirm the pump and hoses are clear before the code will stay resolved.

If the fix involves only emptying the tank and cleaning the electrodes or hoses, there is no parts cost and the repair can be done at home for free. If the condensate pump has failed and needs replacement, parts and labor costs can range from roughly $100 to $250 or more depending on your location and whether you use a service technician. Diagnosing the root cause before ordering parts is always recommended.

Start by removing and fully emptying the condensate tank, then reinstalling it securely. Next, locate the base group reservoir and clean the level-sensing electrodes with a damp cloth to remove any scale or residue causing a false reading. Finally, inspect the condensate pump and all connected hoses for lint blockages, kinks, or debris, and clear anything you find before restarting the dryer.

No, you should not continue running the dryer while E:3 is active. The code indicates the condensate system cannot collect or move water properly, which means water could overflow into internal components or onto the floor. The dryer halts operation for this reason, and normal use should only resume after the issue is fully diagnosed and corrected.
