Karcher hds 2.3 13 c ed will not spray at pressure, bleed

Customer Question

karcher hds 2.3 13 c ed will not spray at pressure, bleed system of air, only hose pressure.

to bleed the pressure washer you attach the hose and turn on the water pressure and then pull the trigger with the electrical power turned off

this just uses the water pressure to push any air out

once you have a steady stream of water coming out then turn the washer on

if this makes no difference then its possible the washer 1 way valves may be worn?

as they rely on a rubber seal which wears out

this video details how this is done

As stated, I have already done that
Expert:  Matt replied 9 months ago.

ok if you've bled it then the next step is to strip the unit down to access the valves

try this firm to supply the parts

Sir, you are not helping, video is not for my unit.
You have told me how to clean or locate spill valve, like web site for Karcher suggested.
Please refund $5.00 and I will not review you.

Left out you have NOT told.... in my frustration
Expert:  Matt replied 9 months ago.


ok if you have the manual then its also worth cleaning out items 15 & 36 ( filters)

Expert:  Matt replied 9 months ago.

the spill valve is typically very similar between all K'archer units so the video of the smaller unit will provide a general guideline
