Hey folks - new Lelit Elizabeth owner here. Experiencing inconsistent results and noticed a big pressure spike on the first shot after standing for a while / the first shot of the day. Subsequent shots go to around 9 bar and stay there with stability. https://youtu.be/b6zMiGLZ1oQ So - is this the issue described in other threads e.g. [https://coffeetime.freeflarum.com/d/116-lelit-elizabeth-pressure-spikinginconsistent/](https://coffeetime.freeflarum.com/d/116-lelit-elizabeth-pressure-spikinginconsistent/ )? If so, would it cause e.g. the inconsistent pull times I am seeing? Am I right in thinking that this is not right? It should be more stable, right?

That's one heck of a spikey spike! My 'liz goes up to 9-9.5 on the first then back down to 8.5 on subsequent shots. I did clean/lube the OPV but it only sorted it in the short term. I'm not getting much difference in my shots fortunately but I'm assuming yours are vastly different with that pressure change!

@"jcb1973"#p7227 All I saw in this shot is a machine going to almost 12 bar and gradually dropping during the extraction as the puck becomes more permeable. > @"jcb1973"#p7227 Subsequent shots go to around 9 bar and stay there with stability. If this is definitely happening, then you may well have the issue?

Thanks Dave / Del - complete newcomer here, seeking first of all to understand if this is normal! Really appreciate experts here who can help - THANK YOU. Excuse my very low level of knowledge, but this is not normal, right? Am I explaining it the right way for my retailer / Lelit to understand? Anything you suggest I should do to demonstrate / identify the issue? Thank you again!

@"jcb1973"#p7230 does it happen with a blind basket and if so does it stay at 12 bar for long?

Thanks Del - yes, happens with blind basket, stays at **12 bar for first shot** (seems to just stay there, not sure how long I should run it?), subsequent shots with blind basket go to **9 bar**.

It is the issue you suspect it is. I have the same problem, sadly took me almost a year to notice otherwise I would just have returned the machine for a refund. Lelit have acknowledged the problem to myself and advised I need a new overpressure valve. Am yet to get a response from Bella Barrista re supplying that part under warranty, but hopefully it gets sorted soon. The issue has been around long enough - surprised they are still selling machines with the dodgy part

> @"Ando"#p7244 surprised they are still selling machines with the dodgy part It's not all machines…although I have an idea of a parts check they can do to possibly find the affected expansion valves. I may well write to them tomorrow. I just need to find a particular image of a faulty expansion valve someone had disassembled at my request and uploaded to the forum.

Ando - thank you so much. I am very tempted to return for a refund, I am super disappointed that my most expensive purchase ever is defective!

I guess the question is also (before I go down the refund route) - is this fixable? It has shaken my confidence in the quality of the machine though. So sad to discover this!!

Is this the "pressure spiking" Lelit Elizabeth issue?

just use PTFE tape when replacing, probably 7-9 wraps in the correct direction. if they have used thread lock, clean it off first.
