Guys I got another device it’s the same issue .. I have a feeling it’s my hoselock connector ... but not sure what to try ?
Yes I haven’t used in a year
Mines been doing that as it’s been idle for months.
My Nilfsk had a different problem, the Lance would always be spraying out a tiny jet of water when not being used and the motor/pump would blip on for a second every 30 or so seconds. Turned out it was small o ring in the lance that needed to be replaced which fixed the problem so do a google and maybe only a small inexpensive part needs to be replaced.
Doubt it's the lance, if it's complete and the trigger is working correctly and you also have the end piece connected with the tiny hole at the end of the lance then it can only be the pump that's knackered.
