I think the same is happening to mine, it goes into Standby and the steam no longer is generated. Try pressing the LHS steam generator button and reduce to medium steam level, this works for me. We have had it a 4 or 5 years, only cost ~£40 (cheap but OK for the price). Time to replace rather then fix I feel, you can get a new latest model Hinari for £50 on Amazon. There are no user-servicable parts. Phone customer services for further advice 0161 621 6900
