What to do if my Landa VNG4-3000 has spark but no pilot gas flow?
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.
Why is the pressure fluctuating on my Landa VNG4-3000?
Fluctuating pressure in your Landa Pressure Washer can be due to: * Worn valves: Check and replace if necessary. * Blockage in valve: Check and replace if necessary. * Pump sucking air: Inspect the water supply and check for air seepage at joints in the suction line. * Worn piston packing: Check and replace if necessary.
What to do if my Landa VNG4-3000 Pressure Washer pump is running but the pressure is low on installation?
If your Landa Pressure Washer pump is running normally but the pressure is low upon installation, consider the following: * Pump sucking air: Check the water supply and look for potential air seepage. * Valves sticking: Check, clean, or replace if necessary. * Unloader valve seat faulty: Check and replace if necessary. * Nozzle incorrectly sized: Check and replace if necessary, referring to the serial plate for the correct size. * Worn piston packing: Check and replace if necessary.
Why is the pump on my Landa VNG4-3000 so noisy?
A noisy pump in your Landa Pressure Washer could indicate: * Air in the suction line: Check the water supply and connections on the suction line. * Broken or weak valve springs: Check and replace if necessary. * Excessive matter in valves: Check and clean if necessary. * Worn bearings: Check and replace if necessary.
