Karcher k399
 

I have had this since may and was using it today with my foam lance. It seams to have a fault. It will constantly turn on and off every couple of seconds.:wonder:

Any ideas anyone?

Sounds like the pump has failed, common enough problem, happened to me twice in the past with units I have owned, should be fixed under warranty by any authorised repairer. :thumb:

I tried a friends gun on it who has the same model and it works ok. Think it must be the gun then:confused:

Odd, from the noise you said it was making I'd have sworn it would have been a pump problem, but maybe it is the gun - just get it into a service agent methinks! :)

Got in touch with Karcher for a new gun under warrenty on wednesday. Received it today and it was the problem after all.
