I have a very recent Elektra MCAL, bought new (from Elektra) less than four mouths ago. Everything was going fine, but now for a few days the lever does not go up properly: it starts going up, then get more or less stuck, and when I assist it to help it going up it does but by making some noise (as if there were a lot of friction).

I have recorded a short video to show the issue:


I have the impression also that the spring cannot apply the proper pressure that way, because the coffee is not good any more...

I have ordered some lubricant, but I have the impression the issue comes from the lever itself. Did one of you already had this issue? What shall I do?

holy cow that is some serious friction occurring if it makes that clicking noise!

I can think of two main things: the seals are extremely dried out and are catching the group bore, or something is happening with the spring that is causing it to not decompress properly.

Before I proceed I recommend popping out the upper group assembly and checking it out. It is only held in by two 3 or 4mm allen bolts and you can just lift it out after.

Thank you for your answer. :)

So I have popped out the lever, and everything seems normal inside, including the seals it seems.

Here is some pictures:






What do you think?

Any obvious issues for you?

I cannot make conclusions of the bore, but it should look smooth with no noticeable scratching or pitting. If the seals do not seem hardened apply some of the lube when you receive it. Look at the spring to see if there are also marks or scratches, as that would indicate where the spring would be rubbing against the bore.

Isn't that scale right there? The white stuff? Anyway I would indeed clean it out and relube or change and lube the gaskets. What kind of water are you using?

I have inspected thoroughly, and I don't see any scratches or marks on the bore or on the spring...

I am using filtered water. I think the gaskets are fine, because the machine is only 4 month old (bought new).

Listening to the clicking again it sounds pretty metallic. The next thing to check is the two pins and the piston rod attached to the upper group assembly. What could be happening is the little rollers are getting stuck and only move again after being pulled by the spring force. I am not sure how far you want to take it apart but those can be relubed and checked to see if that is the case.

Another question I have is if there is stickiness or resistance at all when pulling the lever down.

Well, there's something on those gaskets, not saying the gaskets themselves are bad. Also the grease out of the factory isn't something I'd trust too much but I am comparing to Pavoni :) Wish I had done a relube job on day 1..

I'll look at that, thanks. I'll first wait for my lube to arrive (this Thursday).

Yes, there is some resistance...
