Karcher k4 Pressure loss.
This part along with the pressure manifold restored my K4 to full pressure.

Great product and easy to fit
Having watched a few YouTube videos then fitting was very straightforward - the only tools needed are a long T10 screwdriver, a 6mm allen key and an adjustable spanner. The pressure washer is now running like new.

Excellent Quality for K4 Repair
The cylinder head was an exact match used to repair my Karcher K4 Home 1.180-154.0 T250GB Pressure Washer. First time I've used Ransom Spares but I found the website to be top-notch and it helped me identify this (and several other parts) I needed to repair my PW and I will definitely use them again. I only gave 3 stars for "Ease of Fitting" as I did not find the Karcher to be the easiest appliance to work on but, of course, that is not the fault of Ransom Spares.

Questions And Answers
1 Answer(s)
My karcher k4 refuses to start! It is a premium eco!logic. Over the last year it has given me problems starting. I used to disconnect the high pressure feed to the high pressure hose and reel and sometimes this fired it up but not anymore. I have tried to bleed it, checked the power outlet and the plug, all to no avail. The unit is only 4 years old and very rarely used. Can you tell me what to do and what spare/s I may need. Thanks Dave.
Hi David, unfortunately we're unable to diagnose faults. I'd recommend contacting an engineer or Karcher directly to see if they can advise.
