What to do if burner motor will not run on my Kärcher 1.575-554.0 Pressure Washer?

If the burner motor on your Kärcher Pressure Washer won't run, the fuel pump might have seized; replace it. Check if the burner fan is loose or misaligned; position it correctly and tighten the set screw. A defective control switch should be replaced. Look for loose wires and replace or tighten them. Finally, the burner motor itself might be defective and require replacement.
