Anyone got experience of fixing these things? Mines lost pressure and is
cycling on and off when the triggers released. There are no leaks inside,
I've cleaned the filters, changed the cylinder head. Any ideas?

I spent close on 30 years selling pressure washers & worked for Karcher for
8 years if thats any help.

Tell me what happened before it started playing up. When you shut the
trigger, did the motor switch off completely or did it continue to run as
though idling?

Mine's not a Karcher but A now quite elderly one tha make of which I can't
remember.

Two things I found that can give rise to those symptoms, using a water-stop
hose connector on the end of the hose. It shouldn't in theory, but it does
give problems with mine. It might also be a tiny bit of grit or similar
that's inside the pressure lance. Bit of a bugger to get out, but lots of
back washing as best as possible through the nozzle.

It was working fine before, when the trigger was released it stopped
completely...

The Wanderers advice is sound, waterstop connectors are a no no & it could
have a blocked nozzle. Check those first.

It could be that the pressure switch is out of adjustment. There will be a
cable from the pump head leading back to the electrics box.

its part of the switch box, that doesnt explain the low pressure..

In Germany its 'Keer Ker' AIUI - I don't speak Kraut, in the UK its Karch
Er. Frequently called K -Archer, Carshaw, Kar Cher's etc. The competition
called them 'The Yellow Peril'.

There was a guy, in the very early days of their presence in the UK, who
opened a bank acount in the name of Keith Archer, sold about a dozen
machines & banked the cheques. The Old Bill got him when he tried to sell
the company car near Gatwick, prior to his flight to Spain.

They have suffered from dodgy sales reps claiming machines have been stolen,
reps selling to fake companies they have invented and a completley bogus MD
with false references.

Used to be great kit until they started to cut costs.
