Jaguar F-Type Forum

I was pressure washing the walls of my house yesterday. I’d been at it for an hour or so when suddenly the motor started to scream at very high revs, but the water pressure fell to zero. Turned off the machine. With the motor stopped, water flows through the system and out of the hose nozzle hose. Inlet filter is clear. However, when I turn the switch on, rather than the motor rev and then stop (waiting for the trigger pull to restart it), it revs/screams at far higher revs than normal (like it’s about to explode!). I’ve no idea what type of pump is in there, but it’s as if the paddles have been removed and the spindle is just spinning like mad without getting any ‘traction’ with the water. Any ideas gratefully received - the machine is a few years old now and doesn’t owe me anything, but thought I’d check for an easy fix before a trip to the tip. Thank you! 

Sounds like the coupling between the motor and pump has let go.
Should be a cheap and easy DIY fix.

Modern hp washers unless Pro, aren't built to last long periods of use.

Thanks Tel. Could be a Sunday project.

Search ‘Karcher K2 pump’ on eBay and lots of various parts and designs show up.
Once stripped you can identify what bits fell apart from shaft, gears, etc. and fix if for £20

If not confined to home I’d bin but it's an hours fun to pull apart and satisfying if you do fix it

Thanks cj10jeeper. My thoughts entirely!

Well, I’ve dismantled it. Using all my technical knowhow, I have diagnosed that it is officially buggered. Loads of swarf and bits of gearbox in the pump. Plenty of spares on eBay though as previously suggested, so I’m now in search of the right gearbox and pump assembly. It’s fixable (my wife thinks I’m mad).

Excellent - what a great way to waste half a day of the lock down

Apparently, it takes one to know one.

Sorry to see it was unfixable, though I do see there are various K2 pumps on the bay.

My K2 started springing water from inside last year. Once I got inside (long thin star or torx required), I found it was the pump outlet elbow, which was leaking.

I repaired the leak with epoxy, but the £5 'bay' replacement arrived before the epoxy had cured, so I put that in.

I seem to have entered an alternative reality forum, should my F-type have a Karcher? How about we invent some ventilators too!
