Q: Why does my pump keep running after the tank is empty in automatic mode?

If your SP 17.000 pump continues to operate while the tank is empty in automatic mode, it generally indicates that the level sensor is no longer detecting the liquid correctly . Here’s how to resolve this issue: Checks to Perform Sensor Position: According to the manual, the sensor must be properly positioned on the rail. The higher the sensor is placed, the sooner the pump will stop when the level drops. Ensure it is securely slid and stable on its rail. Sensor Condition: Inspect the sensor for any dirt, signs of abnormal moisture, or physical damage. A dirty or wet sensor does not detect level changes correctly. Contact with the Liquid: The pump automatically stops after about 15 seconds if the sensor loses contact with the liquid. Check that the sensor indeed loses contact when the level drops - if the liquid remains partially in contact, the pump will continue. Type of Liquid Used: Some very viscous or differently composed liquids may hinder proper detection. Ensure you are using a transport liquid compatible with the sensor of this pump. Resetting: Try repositioning the sensor slightly higher on the rail to see if this improves detection and automatic stopping. If after these checks the pump continues to run, the sensor is likely faulty and would need replacement.

Q: What diameter of hose to use with the SP 16.000 Dirt pump?

For the SP 16.000 Dirt pump from Kärcher, the connection has a thread of G 1½ . The compatible hose sizes are: 1" (25 mm) 1¼" (32 mm) 1½" (38 mm) To optimize flow and pumping performance, it is recommended to use a 1½" (38 mm) hose if your conditions allow. Indeed, a larger diameter hose with a shorter length will maximize the pumping power of your device.
