Miele hose end very hard to insert into wand

[mjhoshaw]

Hello everyone, I have a Miele S5280 Callisto that I bought new in 2008. After some use the powered hose's end became very hard to insert into the power brush's wand. Twice I actually sanded the hose end to loosen it up. Now it's very tight again. Any idea what's going on and how to fix it? This is a very annoying problem with an otherwise totally satisfactory vacuum. I will appreciate any help/advice.

Best,

Joel

It depends on how much you've used it. They're meant to last a long time so typically they have tight tolerances that have to be broken in. If you're not daily driving it then it might not be broken in yet.

If you have been giving it regular use I would take a wipe and wipe the inside of the wand and see if there's any dirt that's built up.

It's 13 YO now and is my daily driver. It was very easy to insert the handpiece into the wand when it was new. I'll give it a wipe and see if that helps. Thanks.

Sounds like it could be "out of round".

Both of my Miele vacuums do that. One is the “Aquarius“ and one is the “Gemini“. It is now so difficult to get the hose out of the wand that I do not use the machines anymore.

Could be humidity related causing the plastic to bind together from the temperature of your room or house. Plastic expands when hot, shrinks when cold. When I had some spare vacuum accessories in my garage and I went out to fetch an extension tube when it was like...18 out...really quick, I accidentally dropped it onto the concrete floor. The wand extension broke totally to pieces!

Try rubbing powdered graphite around the inside of one end and the outside of the other where they fit together. Or try a light coating of this (or maybe even some automotive plastic wax - something to thinly lubricate that won't draw dirt) https://www.amazon.com/Jaws-ECOGuard-Silicone-Lubricant-Concentrate/dp/B001BPJFFY

Try

Silicone spray…just a little goes a long way. There could be a build up of dirt inside the wand or the tube of the hose handle. I’d wash both ends that fit together thoroughly then coat with a light coating of silicone spray. If the problem persists check for an “out of round” situation. A lot of people drop their hose handles on the floor or ground with no attachment attached…this will cause an out of round situation. I had this on an Electrolux we found with a hose handle that had been perhaps run over by a car tire…I tried and tried for a long long time to get that handle’s metal end back round again, but never got it perfect so it has always remained difficult to insert and remove. Final solution was to replace the hose handle part which fixed the problem.

This doesn't address the root cause but a solution

It's definitely not an out-of-round condition. I've always been the only user, and I handle this machine with kid gloves. Today I sanded the hose end again but it didn't really help, so I went after the hose end of the PN wand with a rattail file, then four progressively finer grades of sandpaper, testing the fit frequently. As of this evening it couples and uncouples like new. I'm a very happy camper again.

The bigger question is why this happened at all. I never noticed the problem being worse in dry or damp, cold or warm weather. However, just now I did some research and found that some plastic resins are hygroscopic (see below URL for full article):

Nylon, ABS, Acrylic, Polyurethane, Polycarbonate, PET, PBT

These plastics:

- Have a strong affinity to attract moisture
- Will absorb moisture onto their molecular structure if exposed to ambient air
- Internal moisture can not be removed with hot air alone

If the hose end and/or plastic wand insert are made of one or more of the above, that explains it. The problem got worse and worse with time, which seems consistent with the above statements.

Dysonman1, you may want to have a go on your Mieles. Of course this doesn't address the fact that this problem never should've gotten out of R&D.
