I have a hideously expensive Ono Hiflex mixer. It has a unique veg sprayer that when it works is ‘special good’. The why is not for this topic.
But almost like clockwork after about 1 year +/- the sprayer stops shutting off when releasing the trigger, but pushing the sprayer up toward the hose will shut it off. At about 2 years it will not shut off unless manually hard-jammed to the hose.
They have replaced the sprayer multiple times under warranty as well as the ACL. I have a small collection of ‘dearly departed’ sprayers and have managed to take one apart - it is almost like a puzzle to dismantle but appears stone simple inside. It is hard to imagine how it can go bad considering it is nothing more than a spring and a few O-rings all of differing sizes on some plasticy bits.
I asked for instructions on dismantling the sprayer and replacing the O-rings (eg the specified sizes as each seems very slightly different). I presume the problem is a specific O-ring expands a small fraction over time and causes the problem; once it ‘fails’ what is the proper size for each O-ring?
They have refused but so far have replaced the sprayer head (RRP $245!) each time.
The design is faulty since they fail on schedule starting after about a year, and their refusal to date to provide instructions to repair, yet replaced it. I once asked what I might be doing to exacerbate the failure if it had something to do with use. Crickets!
I replaced the O-rings in the first ‘dearly departed’ to see if I could fix it, and discovered it is very sensitive to having exactly the right O-ring at each location, and if an incorrect one is used the sprayer will not shut off or otherwise malfunction. Trial and error using standard kits of O-rings never got me there.
It should be repairable. They will not provide repair instructions. They replace it.
The mixer itself, the veg sprayer notwithstanding, is superb.
