No water presure - Karcher G3025OH Pressure Washer

check the filters

at the intake the solinoids {water intake valves}
there is a small filter

you need to turn of the hot and cold water
like under the sink
take off both hozes hot and cold
then take out the filters at the machine intakes
and clean them
you can take out the filters
using flat nose plyers to gently pull them out
clean them out from brown crypto spyridion carcus
and other rubbish
you can leave the filters out and run thru the whole machine on like 30deg with a calgon tab
does help {not scotland no lime here }
then place the filters in the intakes again
or replace the valve if it leaks water after cleaning
then the spring in the valve of the valves solinoid coils isnt so good
and needs replaced
but can just be a blockage

above all if its a new machine you just got
perhaps it been in a low presure area so the valves will be
low presure hot and cold
usually its just the hot that is low presure

so you need to check the cold water is getting plenty on like 2 -3 bar presure...

sounds like a mix of things

if you have pipes not locked tight
and 1ft = 1 clamp spaces

also check any 'gate' type valves are all fully open
use a presure 'keep' valve regulator to turn down the water presure
to 1.5 - 2 bar {60psi}
if you half close a gate valve
then the whole intake can vibrate and sing
even how much you try to wedge the pips

its the gate valves cause issue
in cold water then it uses presure joints and presure makes the seal
but gate valves will bring like the read in a woodwind instrument like a claronete

so your pipes will sing

check all the filters intake valves at the machine filters
and your gate valves on your water supply to the machines hozes

sometimes the water pressure from the house is insufficient, when it happened to me it would run weird. The water would come out in spurts because little water would come out of the water hose. You could try and lower the pressure on the machine to compensate for the lack of pressure going in, that's all I can think of.

It is under the button cover.

Insufficient gas presure. Check gas presure exiting regulator exrternal of water heater. If presure is at 3.7-inches water column gas valve is defective.

If its a tap refurde to, remove the head at the front of the tap and clean out the filter in front, if the houses warm water has low presure u must find ur presure redusing velve located on main cold feed to geyser and clean the cartrage out revit and ur presure must then be vine , let me know if that dosent help

Hiya,
this can be a water presure issue with your mains or maybe the inlet tap to your machine is not open fully i would surgest checking the connection tap is open fully & allowing the maximum amount of water through to your machine.. if you sink taps run slow then this would be a sign of your water mains presure needing attention.. presure can also be reduced by using water around the house at the same time as the machine is on for example running a bath, dishwasher, flushing the toilet etc.

Hope this helps

Unplug power and remove left side cover. Press down on red breaker switch to reset it.

check your filter on the bottom of the unit on the cold side and see if it's clogged with debris

sounds like a sticky solinoid valve . sometime there is to much water presure in some home witch can cause this problem . chck the water presure is around 50 to 70 lbs . this may cure the problem . excesive presure can actualy hold the inlet valve open.. i hope this helps
