If your Landa Pressure Washer won't timeout, check the reed switch for continuity and replace it if necessary. Also, check the relay cube or relay base for proper continuity and replace if necessary.
How to troubleshoot a Landa Pressure Washer that won't start?
If your Landa Pressure Washer won't start, bypass the timer by joining wires 15 & 16 on the timer together. If it starts, replace the timer.
Why is my Landa PHW3-1100 smoking?
If your Landa Pressure Washer unit smokes, the problem might be due to improper fuel or water in the fuel; in that case, drain the tank and replace the contaminated fuel. Readjust the air bands on the burner assembly if the air adjustment is incorrect. Other potential causes include low fuel pressure (contact technical support), air leaks in fuel lines (check and tighten or replace as needed), a plugged or dirty burner nozzle (replace it), a faulty burner nozzle spray pattern (replace the nozzle), a heavy accumulation of soot on the coils and burner assembly (remove and clean thoroughly), a misaligned electrode (contact technical support), or an obstruction in the smoke stack (check for blockages).
How to fix low water temperature on a Landa PHW3-1100 Pressure Washer?
If you're experiencing low water temperature with your Landa Pressure Washer, start by checking the fuel. Drain the fuel tank and replace it with the correct fuel if it's contaminated. Increase the fuel pressure if it's low. Check the fuel pump pressure and replace the pump if needed if it’s weak. Replace the fuel filter if it's partially clogged. Clean the coils with a soot remover if there's soot build-up, or use a coil cleaner if there's lime build-up. Also, verify you are using the correct burner nozzle by checking the tank assembly parts list.
What causes the water temperature to be too hot on my Landa Pressure Washer?
If the water temperature is too hot on your Landa Pressure Washer, first lower the incoming water temperature if it's warm or hot. Contact technical support if the fuel pump pressure is too high. If the fuel pump is defective, replace it. Tighten all clamps and check the detergent line for holes if the detergent line is sucking air. Replace the high limit switch if it's defective. Ensure you're using the correct fuel nozzle size by checking the exploded view parts list. Check the GPM to the machine if there's insufficient water supplied. Finally, check the nozzle for obstruction and proper size if there's restricted water flow.
Why won't my Landa Pressure Washer system reach full pressure?
If your Landa Pressure Washer system isn't reaching its full designated pressure, check the serial plate for the correct nozzle size, as a worn spray nozzle or one with an orifice too large for the pump flow rate can cause this. Readjust the unloader with a pressure gauge if it's improperly adjusted. Remove and clean the bypass cartridge or replace it if the bypass valve within the unloader is obstructed or leaking. Assure the pump's designated flow rate is adequate in relation to the spray nozzle size.
Why does the unloader cycle in bypass mode on my Landa PHW3-1100 Pressure Washer?
If the unloader cycles while in bypass mode on your Landa Pressure Washer, inspect all high-pressure lines (including the spray gun and hose) for any signs of external leakage and repair as necessary. Also, inspect the discharge valve within the unloader for damage, obstructions, or wear, and replace as necessary. The unloader is not designed for use with a weep gun.
What causes pressure spikes in the discharge line during bypass mode on my Landa PHW3-1100 Pressure Washer?
Pressure spikes in the discharge line during bypass mode on your Landa Pressure Washer can occur if the pressure adjustment is too tight (contact technical support). Ensure the bypass line is a 1/2" inside diameter (I.D.), 12" long, and made of low-pressure flexible hose if there's a restricted bypass line. The unloader flow rate should not exceed 7.8 gpm.
Why is water dripping from under the pump of my Landa Pressure Washer?
If water is dripping from under the pump of your Landa Pressure Washer, check the piston packing, O.R. plunger retainer and ceramics for wear or cracks, and replace if necessary.
Why is oil dripping from my Landa PHW3-1100?
If you notice oil dripping from your Landa Pressure Washer, inspect the oil seal and manifold for wear or cracks, and replace if necessary.
