If the oil is dripping from your Landa Pressure Washer, it's likely due to a worn oil seal. Check the oil seal and replace it if necessary.

Why is oil dripping from my Landa ENG4-2000?
If the oil is dripping from your Landa Pressure Washer, it's likely due to a worn oil seal. Check the oil seal and replace it if necessary.
What causes low water temperature in Landa Pressure Washer?
If your Landa Pressure Washer has low water temperature, the issue could be due to several reasons. The gas lines might be improperly sized, so refer to the sizing gas lines. The gas pressure could be low, so increase the gas pressure to the machine. An improper pressure regulator might be the cause, so specify BTU and building gas pressure (11 w.c.i.) to the machine for correct regulator sizing. Low gas pressure can also cause this, so increase the gas pressure. Soot buildup on the coils can prevent heat transfer, so clean the coils. Finally, the burner nozzle might be improper, so refer to the serial plate.
Why is the pressure low on my Landa ENG4-2000 even though the pump is running normally?
If your Landa Pressure Washer pump is running normally but the pressure is low upon installation, it might be sucking air. Check the water supply for air and inspect for any air leaks. Also, check the valves for sticking, and clean or replace them if necessary. Inspect the unloader valve seat for faults and replace if needed. Ensure the nozzle is correctly sized; refer to the serial plate for the proper size and replace if necessary. Finally, check the piston packing for wear and replace if needed.
Why is the pressure fluctuating on my Landa Pressure Washer?
If you're experiencing fluctuating pressure with your Landa Pressure Washer, worn valves could be the cause; check and replace them if necessary. Another cause may be a blockage in the valve, so check and replace if necessary. The pump might be sucking air; inspect the water supply and look for air seepage at joints in the suction line. Lastly, worn piston packing can also lead to fluctuating pressure; check and replace if necessary.
Why is the water temperature low on my Landa ENG4-2000 Pressure Washer?
If the water temperature is too low on your Landa Pressure Washer, it might be due to an improper size of gas lines. See the section on sizing gas lines for guidance. Low gas pressure could also be the cause; increase the gas pressure to the machine. If the pressure regulator is improper, specify the BTU and building gas pressure (11 w.c.i.) to the machine for correct regulator sizing. Soot buildup on the coils can prevent heat transfer, so clean the coils. Finally, ensure the burner nozzle is the correct one by checking the serial plate.
Why Landa Pressure Washer has low operating pressure?
If your Landa Pressure Washer has low operating pressure, consider these potential causes. A faulty pressure gauge could be the issue, so try installing a new one. Ensure you have a sufficient water supply by using a larger garden hose and cleaning the filter washer at the water inlet. Check if the spray nozzle is old, worn, or incorrect; match the nozzle number to your machine and/or replace it. Belt slippage can also cause low pressure, so tighten or replace the belt, ensuring you use the correct one. Inspect the plumbing system for leaks and retape any leaks with Teflon tape. If applicable, a faulty or misadjusted unloader valve could be the problem; adjust it for proper pressure or install a repair kit if needed. Worn packing in the pump may require a new packing kit.

What to check if my Landa ENG4-2000 Pressure Washer pump runs normally but has low pressure on installation?
If your Landa Pressure Washer pump runs normally but has low pressure upon installation, it could be due to the pump sucking air, valves sticking, a faulty unloader valve seat, an incorrectly sized nozzle, or worn piston packing. Check the water supply for any possibility of air. Inspect the valves and clean or replace them if necessary. Check and replace the unloader valve seat if it is faulty. Verify the nozzle size, replacing if incorrect (refer to the serial plate for the proper size). Lastly, inspect the piston packing and replace it if worn.
What to do if my Landa ENG4-2000 has spark, but no pilot gas flow?
If your Landa Pressure Washer has spark, but no pilot gas flow, the main gas supply may be turned off. Set test meter to 24 volt scale. Be sure main gas valve (gas cock or selector arm) is turned on. With gas on and system sparking, probe terminals PV and 24V(GND). If pilot gas does not flow with 24 volts at these terminals, replace gas valve. Probe terminals PV and MV/PV. If 24 volts not present, replace ignition control box.
What to do if my Landa Pressure Washer has fluctuating pressure?
If your Landa Pressure Washer has fluctuating pressure, it may be due to worn valves, a blockage in the valve, the pump sucking air, or worn piston packing. Check and replace the valves if necessary. Also, check for any blockages in the valve and clear them. Examine the water supply and air seepage at joints in the suction line. Finally, check and replace the piston packing if it's worn.
What causes oil to drip from my Landa ENG4-2000 Pressure Washer?
If oil is dripping from your Landa Pressure Washer, the oil seal is likely worn. Check and replace it if necessary.
