No Pressure I have the 2400 psi Karcher Pressure Washer. I am not receiving any forceful pressure from the unit. What can the problem be?

Here are some possible problems and solutions:

1. Insufficient water suppy. Make sure your using a 3/4" diameter hose, The more length of hose the less water pressure you have so keep the supply hose as short as possible.
2. Plugged Pump Inlet Filter. Check and Clean.
3. Wrong Nozzle. Make sure you have a high pressure nozzle installed on the wand.
4. Plugged Nozzle, inspect and clean.
5. Worn Nozzle, inspect and replace.
6. Leak in pressure hose, inspect for damages and replace if any.
