What to do if my Landa PGHW5-3500 has fluctuating pressure?
- M
  Mr. Ryan WilliamsSep 3, 2025
  If you're experiencing fluctuating pressure with your Landa Pressure Washer, start by checking the valves for wear or blockages, replacing them if necessary. Also, examine the pump for air leaks in the water supply line. Inspect the piston packing for wear and replace if needed. If you are operating a gasoline engine at a high altitude (above 1000 feet), it may be necessary to install a high altitude main jet in the carburetor. Contact your local authorized engine sales and service center for details.

  If the burner on your Landa Pressure Washer won't light, start by checking the fuel level and filling the tank if it's low. Ensure you're using the correct fuel and drain the tank if there's water contamination. Inspect the fuel line for clogs and clean or replace it as necessary. Replace the fuel filter if it's plugged. Make sure the burner air bands are properly adjusted for a clean burn. Check the fuel pressure from the fuel pump, increasing it to the specified level or replacing the pump if needed, using a pressure gauge for testing. Test the burner transformer for a proper arc between contacts and replace it if faulty. Finally, examine the electrical wiring for disconnections or shorts, ensuring all wire contacts are clean, tight, and free of breaks.

  Michael SteeleAug 27, 2025
  If you find water in the oil of your Landa Pressure Washer, it could be due to a worn oil seal, which should be checked and replaced if necessary. High humidity in the air can also contribute to this issue, in which case you should check and change the oil twice as often.

Why is the pressure low on my Landa PGHW5-3500 Pressure Washer after installation?
- M
  Matthew RamosAug 26, 2025
  If your Landa Pressure Washer is running normally but the pressure is low upon installation, several factors could be the cause. The pump sucking air can lead to reduced pressure, so check the water supply and for any potential air seepage. Sticking valves can also affect pressure, requiring you to check, clean, or replace them if necessary. Ensure the nozzle is correctly sized; refer to the serial plate for the proper size and replace if needed. A faulty unloader valve seat should be checked and replaced if necessary. Finally, worn piston packing can also contribute to low pressure and should be inspected and replaced if necessary.

Why is water dripping from under the pump of my Landa PGHW5-3500?

  diana03Aug 25, 2025
  If you notice water dripping from under the pump of your Landa Pressure Washer, it could indicate a few issues. Worn piston packing is a common cause and should be checked and replaced if necessary. Similarly, a worn O-ring plunger retainer can lead to leaks and should be inspected and replaced. A cracked piston can also cause water to drip from under the pump, requiring replacement. Check the water supply pressure and do not run with spray gun closed longer than 2 minutes.
