- B
  Brandon RobertsAug 25, 2025
  Low water temperature in your Landa Pressure Washer may be due to several reasons. Start by ensuring you are using clean and proper fuel. Low fuel pressure can also cause this issue, so increase the fuel pressure. A weak fuel pump should be checked and replaced if needed. If the fuel filter is partially clogged, replace it. Soot build-up on the coils can prevent heat transfer, so clean the coils. Finally, ensure you are using the proper burner nozzle as per the specifications.

How to fix a Landa Pressure Washer burner that will not light?
- D
  Danielle OwensAug 27, 2025
  If the burner on your Landa Pressure Washer won't light, start by checking the fuel level and ensuring you're using the correct fuel. If the fuel line is clogged, clean or replace it. A plugged fuel filter should also be replaced. Make sure the burner air bands are correctly adjusted for a clean burn. Low fuel pressure from the fuel pump might be the issue; increase the pressure or replace the pump, testing with a pressure gauge. A faulty burner transformer should be tested and replaced if necessary. Also, check the 30 amp circuit breaker and push the reset button if it's tripped. Defective bridge rectifiers or 12 VDC relays should be tested and replaced. Finally, ensure all electrical wiring is clean, tight, and free of breaks.

What to do if the pressure is fluctuating on my Landa Pgdc5-3500?
- L
  Lori WardAug 30, 2025
  Fluctuating pressure in your Landa Pressure Washer can be caused by several factors. Check the valves for wear or blockage and replace them if necessary. Also, the pump might be sucking air, so inspect the water supply and joints in the suction line for air seepage. Finally, worn piston packing can cause pressure fluctuations, so inspect and replace it if needed.

Why is the water temperature too hot on my Landa Pgdc5-3500 Pressure Washer?
- V
  Vincent CarrAug 31, 2025
  If the water temperature of your Landa Pressure Washer is too hot, consider these possible causes: The incoming water might already be warm or hot, so lower its temperature. High fuel pump pressure can also cause this, so refer to the specifications for the correct pressure. A defective fuel pump should be replaced. If the detergent line is sucking air, tighten all clamps and check for holes. A defective temperature switch should be replaced. Ensure you're using the correct fuel nozzle size according to the specifications. Insufficient water supply or restricted water flow (check the nozzle for obstructions and proper size) can also lead to overheating.

Why is my Landa Pgdc5-3500 Pressure Washer not drawing detergent?
- R
  Robert MonroeSep 1, 2025
  If your Landa Pressure Washer isn't drawing detergent, there are several things to check. Look for air leaks and tighten all clamps, inspecting the detergent lines for holes. If the restrictor in the float tank is missing, replace it, ensuring it has the proper orifice. A plugged filter screen on the detergent suction hose should be cleaned or replaced. Dried-up detergent plugging the metering valve requires disassembly and thorough cleaning. High detergent viscosity can be a problem, so dilute the detergent to specifications. Repair any holes in the detergent lines. Finally, ensure the detergent level is adequate and add more if needed.

What causes a Landa Pgdc5-3500 pump to be noisy?
- E
  emillerSep 2, 2025
  A noisy pump in your Landa Pressure Washer can be attributed to several factors. First, check the water supply and connections on the suction line for air in the suction line. Also, broken or weak inlet or discharge valve springs should be checked and replaced if necessary. Excessive matter in the valves should be checked and cleaned. Finally, worn bearings can cause noise, so inspect and replace them if needed.

Why is the pressure low on my Landa Pgdc5-3500 after installation?
- M
  Matthew RobinsonSep 4, 2025
  If your Landa Pressure Washer pump is running normally but the pressure is low after installation, several factors could be responsible. The pump might be sucking air, so check the water supply and for any air seepage. Sticking valves should be checked, cleaned, or replaced if necessary. Ensure the nozzle is correctly sized; check and replace if needed, referring to the serial plate for the proper size. A faulty unloader valve seat should be checked and replaced if necessary. Finally, worn piston packing can cause low pressure, so inspect and replace if necessary.

Why is water dripping from under my Landa Pgdc5-3500 Pressure Washer pump?
- G
  Glen WilsonSep 5, 2025
  If water is dripping from under the pump of your Landa Pressure Washer, it could be due to worn piston packing, a worn O-ring plunger retainer, or a cracked piston; check and replace these parts as necessary. Also, the pump protector may be the cause; lower the water supply pressure and avoid running the unit with the spray gun closed for more than 2 minutes.
