If your Karcher isn't reaching high pressure, and you've noticed the trigger is "pulsing" this could mean you need to replace the cylinder head. The valves in the cylinder head can become blocked and clogged, reducing the tension needed to be able to use the washer to its full potential.
Comes complete with piston seals
This is a genuine Karcher spare, suitable for select appliances in the model fit list.
Please note: For certain models the spare is serial and chassis number dependent. Please contact our call centre with this information so we can advise if the part will fit. Your chassis number will look like: 1.504-604.0, and the serial number will be 6 digits long.

Ref Colbee comment. We mistakenly stated that electric pressure washers do not contain oil. The link given to Stock Number: ES538165 is an oils approved for pressure washer pumps and is suitable.

Sorry, I'm a latecomer to this post, but I beg to differ with the response by staff-member Rory on 3/6/2011 who stated that an electric washer does not need oil; surely, in an electric washer, the swash plate chamber contains oil which is easily lost if the retaining bolts are loosened/removed and the motor is not kept upright.
QWe need the bit that actually attaches to the cylinder head.1 Answer
The part that attaches to the cylinder head has burst due to frost damage. Is this bit available as a spare. At least our cylinder is much bigger than the bit in your image. Can you advise.

QI have a K4-600 PRESSURE WASHER used it once all was fine puy it away for a few months next time I came to use it it was leaking a lot of water and pulsating very badly, bear in mind this was used only once . i cannot see what is causing the problem.1 Answer

It pulses because the high pressure that turns the motor off leaks away. unplug and remove the case. just connect the hoses and identify the area it is leaking. Replace that part to resolve your problem.
