Question about Karcher 2500 PSI Pressure Washer

B302 - unable to start detergent flowing - How should it work?

Using a Karcher B302 pressure washer, OK on water only, but cannot find out how to add detergent; just putting the detergent pick-up tube in the detergent bottle has no effect.
What should I be doing?

    Thanks 'The Power' - I thought that was a fault!

    I have the same problem with my karcher 1400 psi pressure washer. I can stick the tube in the bottle of detergent and nothing happens. My grandfather also has one and it doesn't work either.

    I have the same problem and I can't see the point of having a detergent suction hose if it 'aint goin' to work. Am dropping the Karcher off at the dump and investing in a different brand.

It will only pick up detergent if you use a low pressure detergent nozzle - or no nozzle at all. It also takes a while for the detergent to get to the nozzle.

Likewise same problem, then discovered washer must be on low pressure setting for detegent to work, high pressure setting doesn't permit detergent to flow.

I have a Karcher K3.540 pressure washer. Won't take up detergent and motor pulses ever second if vari-lance increased towards maximim. Motor runs ok at lower pressure but can take 1min to start wh


This fault is within the control head, under the detergent valve is a small spring loaded valve that acts to induce the detergent, this will have failed, the shaft of the component breaks off the disk base leaving a small hole in the centre of the disk. This is enough to allow pressure past the component. The machine will pulse when operated and will not induce the detergent. I've looked everywhere to find this part as I have a karcher with the same fault.

The cleaning solution is not spraying out of my pressure washer.


On pressure washers with cleaning solution pick-up hoses you have to make sure you are using the black, low pressure, soap tip. If you are using the high pressure tips, red, yellow, white or green, there will be too much back pressure at the pick-up tube for it to work properly. If you are using the soap tip, check that the pick-up tube and filter are clean.

I am trying to clean my block paving using my pressure washer Karcher 3.99, which I used successfully last summer, however, it is not cleaning well. I have used the high power nozzle but the power seems...


Hello Sue, you don't say where in the world you live, but if you are attempting to clean dirt and algae off pavers, you need to add a solution to the water jet via the inbuilt attachment. Mix a fairly mild solution of bleach and detergent, pus a dash or deodoriser to the cantainer. Put your karcher on low pressure and give all the blocks a good wetting. Do this in the morning so the solution doesn't dry. After 20 ~30 mins, Claen off with the Karcher on normal high pressure (not the tubo lance). HINT: Leave the trigger on all the time and don't stop and start using it. This will prevent hayraulic hammer which can split the pump head.

Using detergent


The first thing to do is check the nozzle setting on your spray lance. The nozzle setting is adjustable (by twisting it) and, if it's set to high pressure, cleaning fluid will not be drawn up from the reservoir. Cleaning fluid will only be drawn from the reservoir when the nozzle is set at low pressure. (Even at the low pressure setting, this problem can occur if you use an extension high-pressure hose.)
You say the machine has never been used, so the nozzle setting is the most likely cause of your problem.  Other possible causes are highly unlikely to occur in a new machine.  If adjusting the nozzle doesn't help, I suggest you contact the dealer from whom you bought the machine.
I hope this helps.  Your feedback is valuable to me so please remember to rate this response.
