When i shoot the water out of the nozzle there is no pressure and the machine shakes like crazy

blockage in the wand nozzle jet

the load in machine is unbalanced. See if the machine shakes with just water in it. If it does not, then the clothing load is not the problem and there is another issue with machine.

On lots of units when this happens a buzzer goes off .

So when you are using the machine & keeping the trigger pulled open the machine builds up to pressure then knocks off all the time.
If this is so the machine is not at fault & is doing what it is meant to do & protect its self from over pressuring & the fault is in the nozzles you are using.
You need to check the nozzle size is correct for the machine & also airline the nozzle to clear of any dirt.
Thanks qwashers

Is this a problem? What is "Like Crazy" ???
Normally this is a good thing.
Exactly what do you mean?
Water shooting out, is Pressure.

The easiest way is to remove the top panel of the machine. There are 4 screws in back that hold the top of the washer. Remove the bottom screws and push the top rearward to remove the top. You can access the hose from the top and reconnect the hose.
Good luck

Deliming

SUGGESTED CLEANING SCHEDULE

Type of Water Cleaning Frequency

Soft water every 80 brew cycles, Hard water every 40 brew cycles

Your espresso maker may be delimed using one quart of white household vinegar. Clean the water tank first, following steps l-5:

1. Make sure the steam control knob is in the center off position and that the plug is disconnected from the electrical outlet.

2. If the machine is cool and the pressure has been released, remove the pressure cap and pour 10 ounces of undiluted white household vinegar into the water tank.

3. Screw on the pressure cap and allow machine to sit overnight with the vinegar solution in the water tank.

4. Remove pressure cap and discard vinegar through the top opening of the espresso maker.

5. Rinse the water tank thoroughly with tap water, repeating this step twice.

To wash internal parts:

Make sure you clean the inside of the water tank first. Remove the pressure cap and pour 10 ounces of fresh white household vinegar into the water tank. Screw the pressure cap back on top of the water tank. Make sure the cap is on tight. Insert the filter holder into the brew head and place the glass decanter with lid on the drip tray. Plug the machine into the electrical outlet and turn the power switch on. An indicator light on the power switch will tell you the machine is on. Place a cup with cold water under the steam nozzle. When vinegar begins to flow into the decanter, insert the nozzle into the water and open the steam nozzle slowly by turning the steam control knob downward. After a few seconds, close the steam nozzle by turning the knob back up to center. This will clean any residue left in the nozzle from frothing milk. When all the vinegar has been pumped into the decanter and the flow has stopped, turn the power switch to the center off position and allow the machine to cool. Repeat steps 1-7 twice using only tap water to rinse any remaining traces of vinegar out of the machine.

Decanter cleaning

1. Pour warm white vinegar in the decanter and let soak for 20 minutes.

2. Discard the vinegar, Wash and rinse the decanter thoroughly using a

soft cloth. Do not use harsh abrasive cleaners.

that is sure signal of insufficient water supply!

try easy solution first:
make sure that your mains is fully open, that tap on whihc hose is hook up is fully open and hose is of "decent" diameter to allow sufficient flow.

if above solution do not work then you need to make another, more difficult arrangement:
prepare 20litres pressure tank with inlet connected to mains and outlet by short hose to power washer, fill it with water from mains, keep it under mains pressure and use karcher power washer normaly. this will solve water supply problem. twenty litres will last about 2min, because it is re-filled, under standard pressure therefore it will last about 3min...

third possibility is to stop washing...

if you find my advice helpfull, please do not hesitate to left the comment and vote for me, thanx!

Since you did not mention the pump brand or type. I will just assume it to be a pressure washer, complete
with gun. The pump comes two suction hoses. One for the water supply and one for the soap bottle or pail There is pressure adjuster right at the pump near where the hose is connected. You can adjust to higher pressure by turning it clockwise. You can adjust the nozzle spray pattern by turning it. However, if your pump comes with only one set of suction hose. Then, it is designed to get the water
supply from the faucet with hose bib. The only one
set of hose is for the soap bottle or pail. It will **** the soap once the nozzle spray is opened.
hose,

The engine doesnt matter. Most pumps are DeVille Bliss. Get the model off the pump and go to their website for trouble shooting information.

Yes, you're machine is identical to the xp7240. Look up the post on leaking xp7240 and follow the instructions on how to open the machine and fix the valve.
