Heos water filler cap stuck (1 Viewer)

[Stretto Boy]

I bought a Heos water filler cap for our previous van, which was a Chausson, and was very pleased with it. I used it for the first time tonight on our new van, an Auto-Sleeper Broadway, and it has stuck in the filler inlet. It was a little bit stiff when I replaced the usual filler cap with the Heos, but not unduly so, and I did not anticipate any problems when removing it. However, it appears to be completely stuck. It is very stiff and I can barely rotate it and certainly it shows no sign of coming out. I am thinking that I need to remove the filler inlet by undoing the three screws which you can clearly see in the photograph below and then hope that the answer may become obvious. Do you think this is the right way to go, or should I try another method?

I personally would try to get some pliers or grips on it first. There will be a seal behind the inlet that you might damage.

Don't think it would help taking it off.
Try pouring hot water over it.

If worst come to the worst a pair of mole grips and some steady (careful) persuasion should get it off. You can then look at it at a later date to see why and fix?

That is what I would do anyway..

My guess would be that the outer diameter of the heos is just a little too small and some judicious sanding should make it usable. I had a very similar issue with my LPG filler that I fitted.

When you get it free try to find out where it became stuck and perhaps rub it down a little and a smear of silicon grease might help in the future.

You will need to push it in as hard as you can and then turn it so it goes over the lugs...

No, although I'm tempted I'm sayin nowt Smiffy.

Had the same problem, initially, with a replacement water filler cap. Got adjustable grips on it and it removed OK. Coated the inner contact surface with silicone grease and now much easier to remove.

Exactly what I was about to say ... great minds and all that!

We had to get a replacement cap in Germany after it was a job to unlock. Well it looked exactly the same as the old one but when I put it in it locked and unlocked but would not come out.
It was a case of brute force and pulled the lock out the old one, and took the new one back for a refund. Bob.

Have we got it off yet @Stretto Boy ...?

Sadly not but, as we set off early to Wimbledon this morning and are still on the way back, I only had a couple of minutes to attempt it. Will give it a go tomorrow.

at least you can still refill the tank


edit - while trying to be witty I have just had a thought, there are 2 different styles of these, one where you have an overflow from the tank and the other that vents back through the cap, have you maybe tried to fit the wrong one?

not even sure they are a different fitting, just trying to help

 

[Stretto Boy]

Thanks @DavidG58 : I wondered about that, when it was too late of course. I have an overflow tank but not sure which internal fittings to use for the water filler as I don't have the instructions any more!

Thanks @Minxy Girl : that's very helpful and ressures me that the cap is the correct one and has the right fittings inside. I shall progress my efforts to remove when I get back from London.

 

[Stretto Boy]

It's out! Tried a bit of pushing, a bit of pulling and a bit of wriggling about and eventually it worked free. It was very hot in London this morning, so don't know if that may have helped a bit. Thanks all for your suggestions : I will follow the ones for lubricating it so that it doesn't happen again.

Been reading forums about these filler caps that you supposedly unlock by turning the cap anti-clockwise with the key in until it spins and then pushing in the cap and turning it anti-clockwise with the key out. .. What do you do next when this does not work. This is on a vw camper king conversion which my son bought 2 weeks ago. How do you get it out!!!!!!!!!

Is it worth trying a bit of pushing, a bit of pulling and a bit of wriggling about in the hope that eventually it works free? Of course, my Heos doesn't have a lock so different pull, push and wriggle techniques may be required. It may help if performed on a hot day and ideally in London. No guarantees but it worked for me. Best of luck.

 

[Silver-Fox]

I'm a bit confused, I know not difficult but where is the lock on these.

I thought they were just for filling then you removed it

I assume it's something like this @Silver-Fox :

I think we are at cross purposes here, the original thread was about the Heos water filler (ie filling up) cap, not the usual locking 'dust' which Chris664 is talking about.

For @Chris664 - as well as turning the key have you tried pushing the cap in hard whilst turning it both right and left, they can be quite stiff and stick a bit so this should hopefully ease it, you could also try doing it on a cooler day as the seal won't 'grip' so much.

Broke my cap off - replaced it with a top off an aerosol can - 'temporary' fix




......it's still on !

In gliding the average life of a temporary repair is generally about 5 years!!!

Someone said hot water.? Any alternatives to silicone grease. Haven't got any. What about clean cooking oil. Would that work?

 

[Imala730]

To minxy girl. Tried wiggling it afraid if we push too hard we will dint the metal as this is a conversion. Will try again tonight. Thank for all the replies. Really do appreciate the Info and help you get on this site.
