Why is the operating pressure low on my Landa Pressure Washer?
- L
  Latoya GrossAug 17, 2025
  Low operating pressure in your Landa Pressure Washer can be caused by several factors. It could be due to an insufficient water supply, such as a closed faucet or a garden hose that's too small. Make sure to use a larger garden hose, clean the inlet water screen, and fully open the faucet. Other potential causes include an old or incorrect spray nozzle (match the nozzle number to your machine or replace it), plumbing or hose leaks (check for leaks and re-tape with Teflon tape), a faulty or mis-adjusted unloader valve (adjust the unloader for proper pressure), the machine being stored in freezing temperatures (thaw it out completely), or slow engine RPM (it is better to call local dealer).

  If your Landa Pressure Washer's engine won't start or stops during operation, it might be due to the low oil shutdown feature. Refill the engine with oil to resolve this issue.

  Dr. William Esparza DDSAug 22, 2025
  If the engine of your Landa Pressure Washer is overloaded, it could be due to a partially blocked nozzle (clean the nozzle) or excessive pressure from high engine RPM (adjust the engine throttle to lower the RPM).

What to do if there is water leaking from the pump protector of my Landa PG?
- A
  Amanda NicholsAug 27, 2025
  If water is leaking from the pump protector of your Landa Pressure Washer, it could be because the spray gun was closed while the machine was running for 5 minutes or longer (open the spray gun or turn off the machine) or due to excessive water supply pressure (place a pressure regulator at the end of the 50' garden hose).

Why is the pressure fluctuating on my Landa PG?
- B
  bonnie29Aug 30, 2025
  Fluctuating pressure in your Landa Pressure Washer can stem from several causes: the pump sucking air (check all pump lines and connections), or gasoline engine altitude (the gasoline engine 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 carburator. Contact your local authorized engine sales and service center for details).

What to do if there is presence of water in pump oil of Landa PG Pressure Washer?
- T
  taylor65Sep 2, 2025
  If you notice water in the pump oil of your Landa Pressure Washer, it could be due to water sprayed at the machine (change the oil and direct the spray away from the machine) or high humidity in the air (check and change the oil twice as often).

What to do if oil squirts out of the oil cap on the pump of my Landa PG?
- B
  Bonnie CastilloSep 5, 2025
  If oil squirts out of the oil cap on the pump of your Landa Pressure Washer, it's likely that the pump is overfilled with oil. Maintain the oil level at the red dot on the sight glass at the rear of the pump or at the top of the notch on the dipstick.

What to do if my Landa PG Pressure Washer engine operates for 15 minutes then stops?
- S
  Stephanie BautistaSep 7, 2025
  If your Landa Pressure Washer engine runs for 15 minutes and then stops, it could be caused by: 1. Not enough gas or engine oil (fill the tank with gas and check the oil level). 2. Vapor lock developed by the heat of the day (keep the gas tank full to avoid vapor locking). 3. Obstruction in the fuel filter (clean or replace the fuel filter).
