Why is the pressure fluctuating on my Landa Pressure Washer?
- A
  Ashley PhillipsAug 25, 2025
  If you're experiencing fluctuating pressure with your Landa Pressure Washer, the valves might be worn or blocked (check and replace if necessary). The pump may be sucking air (check water supply and air seepage at joints in suction line). Also, the piston packing might be worn (check and replace if necessary). If you are using a gasoline engine, it is preset for operation at altitudes below 1000 feet above sea level. If operated at higher altitudes, it may be necessary to install a high altitude main jet in the carburetor. Contact you local authorized engine sales and service center for details.

What to do if the water temperature is too hot on my Landa Pressure Washer?
- K
  Kristine GardnerAug 27, 2025
  If the Landa Pressure Washer's water temperature is too hot, it could be due to several reasons. The incoming water might be warm or hot (lower the incoming water temperature). The fuel pump pressure may be too high (see specifications for proper fuel pressure) or the fuel pump might be defective (replace the fuel pump). The detergent line could be sucking air (tighten all clamps and check detergent lines for holes). Additionally, a defective temperature switch (replace it), incorrect fuel nozzle size (see specifications for proper fuel nozzle), insufficient water supplied (check water G.P.M. to machine), or restricted water flow (check nozzle for obstruction, proper size) could be the cause.

Why is the water temperature low on my Landa Pressure Washer?
- L

  If the water temperature is low on your Landa Pressure Washer, consider these potential causes: improper fuel or water in the fuel (replace with clean and proper fuel), low fuel pressure (increase fuel pressure), a weak fuel pump (check fuel pump pressure and replace if needed), a fuel filter partially clogged (replace as needed), soot build-up on coils not allowing heat transfer (clean coils), or an improper burner nozzle (see specifications).

Why is the pump on my Landa PGHW Pressure Washer so noisy?
- J
  Jonathan RiosAug 30, 2025
  If the Landa Pressure Washer's pump is noisy, it could be due to air in the suction line (check water supply and connections on suction line). Also, check for broken or weak inlet or discharge valve springs, excessive matter in valves, or worn bearings (check and replace if necessary).

Why is my Landa PGHW not drawing detergent?
- B
  Billy PetersSep 1, 2025
  If the Landa Pressure Washer isn't drawing detergent, there could be an air leak (tighten all clamps and check detergent lines for holes). The restrictor in the float tank might be missing (replace the restrictor and check for proper orifice in restrictor). The filter screen on the detergent suction hose could be plugged (clean or replace it). Dried up detergent might be plugging the metering valve (disassemble and clean thoroughly). The detergent's viscosity might be too high (dilute detergent to specifications). There could be a hole in the detergent line(s) (repair the hole). The detergent level might be low (add detergent, if needed).

Why is the pressure low on my Landa PGHW Pressure Washer after installation?
- M
  Michael GomezSep 3, 2025
  If the Landa Pressure Washer pump is running normally but the pressure is low upon installation, it could be due to the pump sucking air (check water supply and possibility of air seepage). The valves might be sticking (check and clean or replace if necessary). The nozzle might be incorrectly sized (check and replace if necessary, see serial plate for proper size). The unloader valve seat might be faulty (check and replace if necessary). Or the piston packing might be worn (check and replace if necessary).

What to do if the burner motor will not run on my Landa PGHW Pressure Washer?
- H
  Holly JacobsSep 5, 2025
  If the burner motor on your Landa Pressure Washer won't run, the fuel pump might be seized (replace fuel pump). The burner fan might be loose or misaligned (position correctly, tighten set screw). The control switch might be defective (replace switch). There might be a loose wire (check and replace or tighten wiring). Or the burner motor itself might be defective (replace motor).

Why is water dripping from under the pump of my Landa PGHW Pressure Washer?
- B
  Brian JohnsonSep 7, 2025
  If there's water dripping from under the pump of your Landa Pressure Washer, it could be due to worn piston packing (check and replace if necessary), a worn O-Ring plunger retainer (check and replace if necessary), a cracked piston (check and replace if necessary), or the pump protector (lower water supply pressure and do not run with spray gun closed longer than 2 minutes).

Why is oil dripping from my Landa Pressure Washer?

  Justin CurtisSep 9, 2025
  If you notice oil dripping from your Landa Pressure Washer, it's likely due to a worn oil seal. Check and replace it as necessary.

Why is there water in the oil of my Landa Pressure Washer?
- A
  Adam WallerSep 12, 2025
  If you see water in the oil of your Landa Pressure Washer, it's possible that the oil seal is worn (check and replace if necessary). High humidity in the air can also contribute, so consider checking and changing the oil twice as often.
