    Head unit gasket

    Didn't actually need this but bought it just in case as if your going to spend time fixing your pressure washer, it's a shame if the head unit leaks afterwards. Mine came apart quite easily and the gasket was intact. Others may not. Worth the extra few quid.

Answer this question

The washer leaks from the yellow box when I am using the hose, and so the pressure in the hose is too low. I don't know which parts I need to buy to put this right ? Is it this form seal ?

    The leak could be from any part of the pump. You will need to disconnect the power and remove the case before only connecting the water to identify where it is leaking from and what individual part is required.
