How can I fix my PRO1600PWA pressure washer?

Worked for me.

I was just about to bin mine and get a new one but have cleaned out the plunger on the pressure switch as described and now its working again!

Happy days

This fix worked perfectly on my machine.
It's old but not done a lot.
Thank's for posting the tip.

Thanks Tony T

This worked.

The handle slides off towards the front of the machine. There are two screws that hold the front cover in place under the handle. When these are removed take of the nut on the outlet pipe, and the front cover lifts out.

The pressure sensor is a small plastic box with a white label that comes out of the top of the pressure control unit, and is held in by quite a small nut.

Thanks again Tony.


"I have just repaired mine, It was a pressure switch, quite easy to repair.
Take off the handle, (2 clips and 2 screws), take the front off the machine, (2 screws and the hose connectors).
There is a small black box with a serial no. on it - joined to the top of the pump and has a wire that i think goes to the main switch.
I used a 13mm spanner to undo it, take it off carefully, it has a spring in it that should push a brass plunger down. The plunger controls a small pessure switch in the box. On mine the plunger was a bit gunged up after standing 12 months!! I used some long nose pliers to take the plunger out , clean it and put some teflon grease on it. I then reassembled and all works well. It has stuck again but now I know what to do.
Don't forget to unplug from mains etc before you start!!
It worked for me, I hope it does the trick for you. Good luck
