I have a KEW Hobby pressure washer ...... been great to date ... but
yesterday started surging.

This is significant enough to make it useless, almost equal cadence
between pressure & no pressure ... the outlet pressure gauge is also
reading nothing ... but that may be just a duff gauge.

Anybody any experience with pressure washers ?

No shortage of incoming mains (pressure or flow rate) even tried
different hoses & fittings to be 100% sure of that.

If I operate lance without unit being switched on ... water is
jetting out OK.
Plus when it 'surges' it does seem right pressure and flow at the
peak of each surge.

I had a similar problem with a Karcher - and prodding some grit out of the
jet with the provided 'prodder' did the trick.


Changed lance to scrubber unit ... still the same, so not related to hose or
lance.
