Pressure Washer Cylinder Head
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.
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.

I have a Karcher 420MH model and seem to have a water leak around the cylinder head area. Is this a common fault and can it be fixed?

Had the same problem with a 380. Tried to repair but the pressure is too great( shows how good the Karcher is). Bought a new head of espares, stripped and fitted in about 35 minutes.

I have changed the cylinder head and checked the water filter in the inlet but the problem persists. What else can be faulty?

If the cylinder head doesn't fix it then try replacing the Control head which is the plastic housing which sits on top of the cylinder head

Hi Softy, if you have a petrol pressure washer, the oil you need to use to keep the engine lubricated can be found here: http://www.espares.co.uk/parts?k=pressure+washer+oil. If you have an electric washer, you won't need oil.

i have a karcher 4.91 which pulses during operation i have stripped it down and not found any obvious cracks but there is a dribble between the cylinder head and aluminium body during operation. do i need to replace the cylinder head or housing or seals etc???

I assume that the machine pulses when you release the trigger. Any sign of a leak will cause this as the machine needs to maintain pressure in order to keep the motor switched off.
Also, a pocket of trapped air within the valve gear will have a similar effect.
