What to do if the main burner won’t come on in my Kärcher Pressure Washer?
- B
  Brenda RiceAug 21, 2025
  If the main burner of your Kärcher Pressure Washer won’t come on even though the pilot light is lit, several issues could be the cause. Begin by testing the wiring for any faults. A low pilot flame can prevent the main burner from igniting, so check the inlet pressure and pilot orifice. Make sure the sensor is properly aligned in the pilot flame; adjust if necessary. A faulty main gas operator in the gas control could also be the culprit, so test the gas valve and repair or replace it. Finally, a faulty flame sensor can cause this issue, so test the sensor and wiring, repairing or replacing as needed.

  If the pressure of your Kärcher Pressure Washer is fluctuating, it could be due to several reasons: a worn or blocked valve (check and replace if necessary), the pump sucking air (check the water supply and air seepage at joints in the suction line), or worn piston packing (check and replace if necessary).

  Felicia RoblesAug 27, 2025
  If your Kärcher Pressure Washer's main burner shuts down, several issues might be responsible. A low pilot flame could be the cause, so check the inlet pressure and pilot orifice. Improper alignment of the sensor in the pilot flame can also lead to shutdowns; adjust the alignment as needed. Additionally, a faulty main gas operator in the gas control could be the problem, so test the gas valve and repair or replace it. Lastly, a faulty flame sensor can cause the burner to shut down, so test the sensor and wiring, repairing or replacing as necessary.

Why is my Kärcher Pressure Washer pump noisy?
- L
  Laura CummingsAug 29, 2025
  If your Kärcher Pressure Washer pump is making excessive noise, it could be due to several factors. Air in the suction line is a common cause, so check the water supply and connections on the suction line. Broken or weak inlet or discharge valve springs can also create noise, so inspect and replace them if necessary. Excessive matter in the valves can cause noise, so check and replace the valves if needed. Finally, worn bearings can contribute to pump noise, so check and replace them if necessary.

Why is the water temperature low on my Kärcher HDS NG 4.5/22 Ea St - 1.575-715.0?
- K

  If your Kärcher Pressure Washer has low water temperature, it could be due to several reasons. Improperly sized gas lines can restrict the gas flow, so refer to the Installation Section for correct sizing. Low gas pressure can also cause this issue, so increase the gas pressure as described in the Installation Section. An improper pressure regulator can affect water temperature, so specify the BTU and building gas pressure to ensure correct sizing of the regulator. Soot buildup on the coils can prevent heat transfer, so clean the coils. Finally, an improper burner nozzle can cause low water temperature, so refer to the serial plate for the correct nozzle.
