Plumberpro : if this answers your question could you please give a positive response. If you have further questions ,alternately please post your question
Plumberpro : thanks
Customer: First, I need to know whether our assumption is correct as it is a pure guess as I know nothing about water pressure machines.. Then I need to know how to access the inside of the machine to find the part that needs replacing. Then I need to know where I can get the replacement part!
Customer: I did ask for a detailed reply!
Plumberpro : Hi .
Plumberpro : The link I gave you has a schematic drawing , but you would find it hard to find someone who has repaired this exact model of pressure washer .. The screws are usually easily accessible . If you can get the cover off you may be able to see where it is leaking from .
Customer: Ok. We will try the link. Sorry our messages crossed. I will leave this open until I have had a chance to look at it.
Plumberpro : Thats ok
Customer: We took the screws out of the cover but it didn't come off so we haven't been able to access the inside of the machine at all. Any ideas? Are there some hidden screws or something. It didn't! loosen at all!
Plumberpro : Hi . It looks like the lower front cover comes off .check for screws under control knobs. It may lever off from the under neath as on the drawing it looks like it has a couple of raised bits that hook in at the top of the cover .
