I have a KB4040 karcher pressure washer. The auto cut off for the motor which operates via the trigger no longer works. I notice you sell an electric box for this model would you advise this as a solution.

The machine also pushes water out through the plastic low pressure tube to the washer bottle when operated on high pressure. Any ideas please.

    Hi there, the auto cut off failing could well be an electronic failure, which would probably mean replacing the electric box. However before reaching that conclusion, check all the physical parts (the trigger, the hose) that control the auto cut off, as it could be a mechanical failure. With regard to the detergent hose, check it for splits. If it looks ok, it'll probably mean an o-ring has split or perished, allowing water and detergent to leak.
