Ok found the problem...this washer has come off and is a bit mangled ☹️

Guess they did take it off and didn’t refit correctly..  😩

I’ve tried to flatten it but keeps slipping so will have to speak to them about getting another one. 
 

Anyone know if there is supposed to be a gap between the washer and the brass collar?

You couldn’t write this script... 😞

I'm actually investigating myself. I have the current program logic from Lelit. My MaraX is back in service. At the moment I have installed prototype software onto it with completely different functio

Finally, all tidy and ready for the morning now...

Could you do a photo with the whole assembly, knob valve, the knob removed if it's now loose, is there a thread inside that domed thing.

This is a photo of the hot water wand

this is of the now bodged steam wand

there’s clearly a gap so I’m wondering if that is supposed to be there and why it got bent and came off in the first place.

Oh for goodness sake.. that is terrible, but an easy fix all the same with the right new parts. In some ways this must be preferable to an electronic fault again of some description. Arrrgghhh!!

In the interests of correct information for people who read this thread, and so they don't get confused. I took the trouble of making a little video. In the video I explain how the knob works.

The explanation for how the circlip can get bent is simple (and it can only really get bent one way outwards). When the steam wand is opened fully, it comes to its stop, the end point. If more force than is reasonable is applied, then the circlip can be bent outwards as attempts are made to unscrew the knob further. This is the only way it can be bent like in your photo. It's not possible to do as per the photo on fitting or removal...if it is, then I would have to be shown, because I can't think of a way.

 

 

I would imagine an auto parts shop/or similar hardware type store would probably have a similar circlip...as it's a PITA to wait for such a small part and I would imagine they are not a stocked spare...perhaps they should be.

 

P.S. I should make the point that the valve is probably fully open at least 1/2 a turn before the valve comes up against it's stop.

Thanks Dave. Makes sense.

I can assure I have treated this machine with the gentle respect of a new born baby. No excessive force applied at all. Just finger tips.

It got bent while it was out for repair. Possibly they forgot to remove it while attempting to unscrew the knob. I know they did something with the steam wand as it was limp when it came back and the nut was not even finger tip tight.

It is a huge PITA and I have temporarily swapped it over with the hot water wand until I can source the part.

Might be an obvious point, but just in case you haven't tried - if it is bent, maybe it can be bent back (like in a vice or with pliers, or maybe even returned to the machine inside out and unscrew the knob to put pressure to try and straighten it, even as a temporary solution till you get a new one)?

I did flatten it with pliers and teased back into shape as best I could by it’s a bit temperamental now so swapped with hot water tap which I can live without for a bit. 
 

I’ve got a link to a new one so going to try and order tomorrow ☺️

On the positive side the posts have elicited some useful information for people.

@MonkeyHarris - Not tried to order from them since Brexit but these people were great in terms of Lelit spares.

I think the Mara-x and Mara PL62 wands are the same fittings, so you can get a full replacement one with seals etc for not that much if you need one down the road.

Good afternoon!

Well, I have my MaraX back in action and all seems to be functioning well thus far (sorry @MonkeyHarris 😞).  
 

I haven’t gone beyond making a first round of drinks yet but have experienced no pressure loss and the MaraX is acting as it always did when it worked properly.

I’m absolutely sure that my MaraX works as it states in the manual and @DavecUK’s review:

Mode 1:  Coffee Priority (X)

Mode 0: Steam Priority (HX)

In mode 1 (X), I experience a steam boost after pulling a shot which results in circa 1.5 bar steam pressure.  When left for a while, the steam pressure is idle at around 0.6 - 0.75 as expected.  
 

In mode 0 (HX, (set to temp II under drip tray) the steam pressure stays idle at circa 1.6.

Nothing else to add - it’s simple and unless anybody else’s machine does the opposite, there shouldn’t be any confusion 😂

P.s. thanks to BB for fixing the issue with the faulty temp sensor!

Glad it’s fixed.

Mine is working fine but for the damaged clip, which I’ve temporarily swapped with the hot water tap.

I’m using mine the same as you. Mode 1 as I notice a difference in extraction  temp when using the drip tray PID settings. 
 

Oddly though mine idles at 1 bar in HX and 0.6ish in X mode. Either way it seems to steam fine now.

2 down, 1 to go 😁

Brilliant stuff, that's good to hear that it is all sorted too. UPS dropped mine off at BB this morning at 9:20, so I am hoping to hear back from them a bit later on... I wonder if my sensor is faulty too?

Very odd that BB keep pedalling the 'reversed' HX / coffee mode switch thing...

This surely depends upon the drip tray 3 way selector?  I set mine at ‘II’ for the HX mode test to get the highest idle steam pressure.

When the 3 way selector is at ‘0’, mine probably would sit at 1 bar when idle..

Good point 😁

That’s why I need this forum’s

This^^^!!  I can only comment on mine - maybe Lelit made lots of machines with this  reversed.  Mine came back in mode ‘0’ also, not that it means anything.

Might be 3 down, if you count the message in the main Mara X forum from @Merchant-Seaman - not the same issue (loss of steam power, quite the opposite), but the same culprit: faulty temp sensor in a two-month old machine. 

Wonder how many more issues coming from these sensors will arise. Doesn't instill much confidence. Hopefully it's a bad batch issue and won't affect too many machines.

FYI, my steam pressure has gone down to nearly 1 bar when I switched back to ‘0’ on the temp switch in HX mode.

BB are charging these repairs to Lelit so I guess it’ll be in their best interest to get it fixed quickly.
