Steam Wand leaking after use

Recommended Posts

Hi all

I'm pretty new on here but have actually been lurking for a while now!! Currently my setup is a pre 2008 Gaggia Classic with Rancilio steam wand upgrade and Gaggia Grinder.

Just wondering if anyone has any ideas to help, after using I walk away with the machine left on and water runs from the end of the steam wand (it also does the same if I turn it off after use)

I'm presuming the seal has gone but before I take it apart and find the issue, has anyone had the same issue and know which part I need to order and replace.

Thanks in advance.

Wayne

The steam valve is a pretty common failure on these. It can also fail to seal due to limescale particles getting in the mechanism. A good descale/flush might help if you have reason to think that might be the case for you, if not replacements are easy to get (£50ish).

I’m going out on a limb and guessing you aren’t the machines original owner.

 

Beings that it’s over 10 years old it’s probably due a full strip and descale.

 

Great vid here, not as hard as you might think. The only thing I’d say is don’t bother with citric acid, get some Calcinet or similar product - it’s not expensive for the amount you go through domestically.

 

 

That would be a good starting point, see if the issue persists. Given that it’s the steam valve that’s leaking, it might pay to remove it from the boiler and give it a good soak in calcinet solution, with the other parts of the machine. A word of caution - there are 4 electrical connections to the heating elements on top of the boiler - try to avoid getting them wet (I taped them up with electricians tape when I recently did this), some people have experienced problems with the unit tripping after submerging the entire boiler for cleaning.

 

Also, whilst you’re doing it you may as well replace all the seals, kits with all the replacement seals for every connection on the unit are available for £5-10, I got mine on eBay recently.

 

My advice is to do this before buying any parts - it’s amazing how many things can be fixed by stripping them, cleaning them and putting them back together!

 

Good luck!

Cheers guys and yes I'm not the original owner so probably due a full clean and service. I've just got to free up the time to do so now ??

Probably takes about 2-3 hrs start to finish. I’d allocate an evening, that’ll give you plenty of time to do it properly and take your time.

 

Just be careful when you un-do the boiler fixing and group head bolts, use a decent quality hex key if you can and make sure it’s properly engaged. Last thing you want is to start stripping bolts.
