What to do if my Landa Pressure Washer has spark but no pilot gas flow?
- J
  Jesse BryantSep 8, 2025
  If your Landa Pressure Washer has a spark but no pilot gas flow, first ensure the main gas supply is turned on by checking the main gas valve. If the gas is on and the system is sparking, test the voltage at terminals PV and GND. If pilot gas doesn't flow with 24 volts present, replace the gas valve. If 24 volts are not present at terminals PV and MV/PV, replace the ignition control box.

What to do if my Landa VNG4-2000 Pressure Washer has pilot gas but no spark?
- J
  Jennifer HahnAug 25, 2025
  If your Landa Pressure Washer has pilot gas but no spark, it could be due to a defective ignitor/sensor or its wiring, or a faulty ignition control unit. Set your test meter to the ohm scale. Touch one meter probe to the tip of the ignitor/sensor rod in the pilot and the other probe to the quick connect at the other end of the ignitor/sensor wire. If you have continuity from the tip of the ignitor/sensor rod to the connector and no spark, replace the ignition control unit. If you do not have continuity through the wire and the ignitor/sensor, check for a loose wire connection in the wire and repair as needed. Also, check if the spark shorts to the burner ring through a cut in the ignitor wire.

Why is the water temperature too hot on my Landa VNG4-2000?
- M
  mariaandersonAug 27, 2025
  If the water temperature is too hot on your Landa Pressure Washer, it might be due to: * Incoming water being too warm or hot. Try lowering the incoming water temperature. * Gas pressure being too high. Contact your local gas company. * The detergent line sucking in air. Tighten all clamps and check the detergent lines for holes. * A defective high limit switch. Replace it. * Incorrect burner nozzle size. Refer to the exploded view parts list. * Insufficient water supply. Check the water G.P.M. to the machine. * Restricted water flow. Check the nozzle for obstructions and proper size.

Why is the pump running normally but the pressure is low on my Landa Pressure Washer installation?
- A
  Ashley LeeAug 29, 2025
  If your Landa Pressure Washer pump is running normally but the pressure is low upon installation, consider the following: * The pump might be sucking air, so check the water supply and look for potential air seepage. * Valves might be sticking, so check, clean, or replace them if necessary. * The unloader valve seat could be faulty, so check and replace it if needed. * The nozzle might be incorrectly sized, so check and replace it if necessary, referring to the serial plate for the proper size. * The piston packing might be worn, so check and replace it if necessary.

Why is the water temperature low in my Landa VNG4-2000 Pressure Washer?
- D
  Darrell CrawfordAug 30, 2025
  Low water temperature in your Landa Pressure Washer can be caused by: * Improper size of gas lines. See pages 7-8 for sizing of gas lines. * Low gas pressure. Increase gas pressure to the machine. * Improper pressure regulator. Specify BTU, building gas pressure and 11 w.c.i. to machine for correct sizing of regulator. * Low gas valve pressure. Increase gas pressure as described on page 14. * Soot buildup on coils not allowing heat transfer. Clean the coils. * Improper burner nozzle. See exploded view parts list.
