  If there is no display after switching on your Kärcher Pressure Washer, the battery might be depleted (charge the battery). Also, check for a blown fuse (replace the fuse). Ensure the front cover is closed. Verify that the emergency stop switch is not depressed (unlock it by pulling). It's also possible there's no power supply to the inverter due to battery undervoltage or overvoltage (check the battery and charge if necessary), or the inverter itself could be defective (replace the inverter).

How to fix ERROR 3 Temperature water inlet or cooling water on Kärcher Pressure Washer?
- D
  David DavisSep 6, 2025
  If your Kärcher Pressure Washer displays ERROR 3, which relates to the temperature of the water inlet or cooling water, there could be several reasons. If the water temperature in the float container is too high due to circulation mode, allow the water to cool down or drain it. If the temperature sensor has switched off the device, turn the appliance off and back on; if the malfunction re-occurs, contact customer service. Other causes may include a defective temperature sensor (replace it), low coolant level (fill coolant into the expansion tank), insufficient V-belt tension on the fan (retension the V-belt), or a defective temperature sensor on the motor (replace the temperature sensor).

How to troubleshoot ERROR 7 Motor oil pressure on my Kärcher Pressure Washer?
- A
  Amy ThompsonSep 4, 2025
  If your Kärcher Pressure Washer displays ERROR 7, indicating a motor oil pressure issue, first check the oil level in the motor and refill if it's low. Also, ensure the motor oil has the correct viscosity grade; if not, perform an oil change. The oil pressure switch on the motor might be defective, requiring replacement. If none of these solutions work, there may be motor trouble; in this case, check the motor.
