My Kärcher K3 Power Control (Max 2100 PSI) has water pouring out of the middle of the unit and the test button on the plug won't turn it on; is there any way to fix this after only one use?

It is highly concerning that your Kärcher K3 Power Control is leaking from the center of the unit and failing to power on after just one use. This combination of symptoms suggests a significant internal failure.Possible Causes:Internal Pump Damage: Water pouring from the middle of the chassis often indicates a cracked pump head or a failed internal seal. If the unit was stored in freezing temperatures with water inside, the pump may have suffered frost damage.Electrical Safety Trip: The "test" button on the power cord is part of the GFCI (Ground Fault Circuit Interrupter). If water is leaking internally, it may be coming into contact with electrical components, causing the GFCI to trip immediately to prevent electric shock. This is why the unit will not turn on.Recommended Steps:Safety First: Immediately unplug the unit from the electrical outlet. Do not attempt to force it to turn on while water is leaking from the housing.Check Connections: Ensure the leak is not actually coming from a loose high-pressure hose connection or the garden hose inlet (yellow quick-connect adapter) and running into the middle of the frame. Tighten all connections and inspect O-rings for damage.Warranty Claim: Since you have only used the unit once, it should be covered under the Kärcher manufacturer warranty. Do not attempt to open the plastic housing yourself, as this will void your warranty.Contact Support: Visit the official Kärcher website or use the Kärcher Home & Garden App to initiate a support request. You can also contact their customer service department to find a local authorized service center for repair or replacement.
