    What to do if the burner will not light on my Landa Pgdc4-3500 Pressure Washer?

      If the burner on your Landa Pressure Washer won't light, start by checking the fuel level and filling the tank if it's low. Ensure you're using the correct fuel and that there's no water in it; if there is, drain and refill the tank. A clogged fuel line or plugged fuel filter can also prevent ignition, so clean or replace them as needed. Other potential causes include mis-adjusted burner air bands (readjust them), insufficient fuel pressure from the fuel pump (increase pressure or replace the pump, testing with a pressure gauge), a faulty burner transformer (test for proper arc and replace if needed), a tripped 30 amp circuit breaker (push the reset button), a defective bridge rectifier (test and replace), a faulty 12 VDC relay (test and replace), or disconnected/shorted electrical wiring ...

Other potential causes include an old or incorrect spray nozzle (match the nozzle number to the machine or replace it), belt slippage (tighten or replace the belt), plumbing or hose leaks (check and re-tape with Teflon tape), a faulty unloader valve (adjust or install a repair kit), worn pump packing (install a new kit), fouled pump valves (clean them), worn valves (replace with a valve kit), a blocked spray nozzle (remove the obstruction), a leaking pressure control valve (rebuild or replace it), slow engin...
