Experience has shown that this is frost damage. To check, please proceed as follows: Loosen the screws in the housing around the hydraulic part. Remove the housing parts (front and rear). Connect the inner hydraulic part to the tap. Open the tap. If water is now leaking from damage to the valve body, this is usually due to excessive internal pressure, e.g. caused by frost.
To obtain a new valve body or to return your Water Computer, please contact your local GARDENA Service Center.
