Genuine Karcher product for select pressure washers. Prior to ordering, please check the list of models to ensure this is the right part for you.
The manufacturer refers to this part as a 'Spare parts set control head' as you may see it advertised on other sites. We have changed the product name to reflect that you will need to use the internal bits from the old part.
Please note: this part is chassis number and serial number dependent - please contact our Call Centre with the full details from your pressure washer data plate.

Ideal, did the job and only a wee bit fidly to fit. Saved having to buy a new jet wash. There are two parts for this problem, very similar but not interchangeable. make sure you call in with the washer serial number to get the correct part.

Had pulsing and low pressure issues so replaced this part. Fitting is simple if you have basic mechanical knowledge and the correct tools. It takes about an hour to complete. It solved the original problems however the [new]outlet pipe was so loose compared with the old part that it leaked badly. The inlet was fine. I stripped it down again but the new part still leaked. Due to the poor quality part and not wanting to throw good money after bad, I binned the Karcher and brought a new Bosch pressure washer - German over Italian every time.

I ordered this part to replace the split head on my karcher. You need to swap over the various little valves and springs etc so a little fiddly but working as good as new now!
I need to know if parts that are normally assembled in the sealed area of the head ( i.e. spring, valve, o-rings,teflon seal etc.) are included in the package, or do I need to purchase them separately?
If Yes could You give me their part numbers?
Thank You

This part comes with nothing! Look for the leak BEFORE you order. Triangular seal is good sense as it is unlikely the old seal will fit well with the new housing - and if you've gone to the trouble of taking it all apart, then another couple of pounds for the seal has got to be worth it!

Hi Sempai, the spring, o-rings, washers and all parts assembled in the sealed part of the head come with the control head.
QCan anyone tell me what the OBJECT is in my image?2 Answers
I lost this part when servicing the control head, it flew out so fast I didn't have time to identify what it is made of or its size.
I don't intend to buy a new control head for just one washer type component.
Any info or pictures would be appericated.
Thanks.

Your picture seems to show more parts that are actually there ! There is just : the black plastic piston , an O-ring ( which you seem to point to ) , a spring, and a little white plastic washer which sits in the bottom of the recess in the control head.
Actually my problem seems to be in the assembly marked 7,...the machine has never lifted detergent from the tank since new,...I should have taken it back then but was too lazy. Now I have dismantled the machine and find that the '7' valve is blocked . Can it be bought separately ?

Hope this helps. Sounds like you've lost the small spring from the middle of the head - I almost did. If you've got a 3.99 like me, there are two different control heads which epares sent me PDF images of to help identify my broken part. Ask them to do the same - don't forget to give them the number embossed on the control head.

Qtriangle o ring under this part does it go in the first or second groove on the head as it fell out when i removed the pressure control head1 Answer

The triangular O-ring seats on the inner groove of the control head, you can tell you have positioned it properly as it does not require any stretching, it just rests in the groove. Use some silicone grease or vaseline to hold it in place as you push the head down on to the pump body.
QDoes the Pressure Control Head housing come with a breakdown of where the little seals and springs go1 Answer

No instructions supplied. Karcher supplied parts diagram pdf for my machine. I rang there helpline and within seconds had the information emailed to me. If you are stripping machine then either take photos as you go or take notes. Wait until new part is ready to install as it is easy to forget and best to tackle job all in one go. Under the white cap in photo you will find the on/off actuating valve preinstalled. On top of that you fit the detergent valve from your old head and also use other parts from your old head. This will cure on off pulsing and leaking because the valve seals wear out with having so much work to do and can't keep sufficient pressure to the recessed switch in the electrical housing.
