If your Kärcher Pressure Washer's pressure is low after a period of normal use, the nozzle may be worn and needs replacement. Alternatively, the unloader valve might be worn and also needs replacing.
What to do if my Kärcher HD 3.5/35 G Pressure Washer has fluctuating pressure?
If your Kärcher Pressure Washer has fluctuating pressure, it could be due to worn or dirty pump valves (contact local distributor). Another cause may be an obstructed nozzle; blow out or remove debris with a fine needle. The pump might be sucking air, or the inlet hose could be leaking; check that all hoses and fittings are airtight, then turn off the machine and trigger the spray gun until a steady flow of water emerges through the nozzle. Insufficient water supply can also cause fluctuating pressure; turn the water on full force and check the garden hose for kinks, leaks, or blockages.
Why is there low operating pressure in my Kärcher HD 3.5/35 G?
Low operating pressure in your Kärcher Pressure Washer can occur due to several reasons. It could be due to an insufficient water supply, a closed faucet, or a kinked inlet hose. Try using a larger garden hose and cleaning the inlet water screen, and ensure the faucet is fully open. It may also be caused by a clogged inlet hose strainer, in which case you should check the plumbing system for leaks and retape them with Teflon tape. Other potential causes include a faulty or mis-adjusted unloader valve (adjust the unloader for proper pressure), worn packing in the pump (contact Dealer Customer Support), the machine being stored in freezing temperatures (thaw it out completely), or a slow engine RPM (contact local distributor).
Why is there water in the pump oil of my Kärcher Pressure Washer?
If you notice water in the pump oil of your Kärcher Pressure Washer, it could be due to water being sprayed at the machine. Change the oil and direct the spray away from the machine. High humidity can also cause this issue; in such cases, check and change the oil twice as often.
Why is my Kärcher HD 3.5/35 G Pressure Washer engine overloaded?
If your Kärcher Pressure Washer engine is overloaded, it might be due to a partially blocked nozzle. Try cleaning the nozzle. Alternatively, excessive pressure from high engine RPM could be the cause. Adjust the engine throttle to lower the RPM.
Why is the pressure low on my Kärcher HD 3.5/35 G Pressure Washer after normal use?
