Details / Specifications

If the pump of your Karcher pressure washer is not working properly, a faulty housing and pressure controller WCP can be the reason. Instead of going out and buying a whole pressure washer, you can replace the controller with a genuine replacement. Manufactured by Karcher, the Housing and pressure controller WCP gets the pump working like before. It is compatible with select models of Karcher pressure washers.

Features:

  • Genuine replacement part
  • Compatible with select Karcher pressure washer models

Karcher K4 Control Head

By Richard Davies - Ammanford - 18th Apr 2018

The part arrived promptly and was easy to fit. This was the second time the control head had failed. I thought the the first time was due to frost. I now realise that the owner does not (prime) let water flow through the unit before switching on the power supply.

Exact replacement

By Tom - Hong Kong - 14th Nov 2017

A bit of a fiddle to fit but exactly as the original and the jet is back as new. Took the opportunity to clean and re-oil the swash plate as well

Worth the effort

By Laurence patterson - Skipton - 24th Jun 2017

Had a Karcher k.4.600 pressure washer that pulsed. Using internet found out what might be wrong. Taking Karcher apart and putting back together was easier than I thought but still required considerable concentration. Ransom Spares quickly responded to my query regarding suitability of part and it fitted perfectly. Very happy with result. Saved the pump and planet!

Good product

By Tommy Oksanen - Salo - 2nd Aug 2016

Works as it should. The difficult part to put, because you have to dismantle the washer so much. But it is not the fault of this part :)

Great product

By Rick - Caldicot - 6th Jun 2016

Bought this item when my Karcher was pulsing/hunting and a leak occurred wasn't sure initially what the problem was but having read some views of possible reasons, opted to go for this part. I stripped down the Karcher taking off the outer casing and then connected the water supply and from that I could see the leak had I not connected the supply I would have never spotted the leak, it was such a fine hair line fracture you would never have known it was there. Refitted the part and works perfectly fine good as new

excellent value and the genuine part

By andrew barber - france - 8th Nov 2015

the only company I could find on-line that stocked the actual part number for my machine. There were a lot of companies offering parts similar to what I needed but not a genuine part. and at an unbeatable price A great site to use - straight-forward - with a massive selection and all at an excellent price. part arrived 3/4 working days to France from the UK - excellent service and will be using them again. Would thoroughly recommend this site.

the right part

By Mr philip allen - fakenham - 8th May 2015

After receiving the incorrect part from a rival it was easy to find the correct item from ransoms and was cheaper too. My karcher pressure washer is now working as good as new.
