I have a Karcher K5.700 18 months old with an intermittent problem.

the pressure drops from full to part while using, e.g. full for 5 seconds then a second at low (repeat) as if some one is turning the water supply off and on. and very occasionally it only runs at half pressure, this can be reset by switching off and back on, but the intermittent pressure problem is annoying . any ideas what's wrong ?
