Having problems with your Pressure Washers ?

We have a Landa with a diesel burner. The problem

\015 We have a Landa DHW4 with a diesel burner. The problem is that when the machine gets hot, it doesn't light everytime the wand handle is pressed and it will back fire severely. We no longer use the heat because the last time it almost took the ends off the burner housing.What is causing this? The fuel is pure and clean and the contacts appear to be in good condition.\015

Answers :

There is a screen in the tip of the spray nozzle for the diesel. Remove the tip and clean the screen. Your getting a explosion because diesel is pooling in the coils and igniting when conditions are right (air/fuel mixture). There is also a screen in the diesel pump. Remove the pump and clean it also. When you split the pump the screen sits between the two halves. Hope this will help.

I have an older Landa Pressure Washer. The burner is not working. Once I get the machine running and water flowing to the pressure washer, with the wand pressed, I flip the burner on switch....and nothing...I have no idea how to work on a pressure washer burner.
