hi guys, i got a problem with the p washer. Been trawling through the posts and can't find anything but think I've seen the answer to this one anyway.

P washer won't start with the lance attached, or will start with the trigger pulled in. However, the engine bogs down when you let the trigger out.With the hose completely detached the p washer pushes out water no problem. The unit has been idle whilst away on holiday but clean the pre filter out prior which was quite dirty. Please help got work tomorrow.

Unloader is not

[rb4no]

hi chris, unloader is not... what?

[BDCS]

The unloader is not unloading, the trapped pressure is not isolated to the gun side as as such the motor is still turning against the pressure. Had similar on mine and replaced the unloader last week.

[chris scott]

Give the unloader a tap with a hammer ...it might just be stuck. My experience is that when they start playing up it's time to replace.
Replace with a SUITABLE k series unloader. http://www.ebay.co.uk/itm/PRESSURE-WASHER-K5-UNLOADER-VALVE-CLEANWELL-WESLEY-/180431788376?pt=UK_Home_Garden_PowerTools_SM&hash=item2a02929958

cheers, I'll give it a knock in the morning and see what happens...

[rb4no]

btw mine has a by pass on it, these can be transferred can't they or does the K series have one built in?

[BDCS]

I've never run a k series so I don't know

Photo of your set up?

It could be the 'bullet' non return valve has a bit of grit or o ring damage... Also....
Try winding your unloader back off, you may have over tightened it

[rb4no]

just gave the unit a couple of gentle knocks with a wrench, started her up unwound and worked perfectly, then wound her up to max pressure and still works great. So problem averted for now, the unit is a small loncin chinese jobby so probably poor quality saying that though, it hasn't let me down yet and the engine 6hp by the way is awesome. cheers, dickie
