Was tidying the workstation this morning ahead of moving to another location. There was a soft 'ticking' noise coming from the machine. So, powered off, ticking still there. Disconnected from mains, moved trolley and ticking still there. Sounded similar to the pointers on an analogue watch. It did eventually stop (maybe someone left an italian watch inside the case when testing) but i'll keep an eye on it. More specifically, an ear. Anyone heard of this before?

@"skylark"#p49600 - when the noise happens, is the machine hot or cold? Does it happens if the machine is plugged in, but it’s cold? If not, then it might be just the machine cooling down, including water in the hoses, fittings, etc.

Back again. Been using the machine this morning, switched it off after cleaning around 4pm and have just had another listen. It still ticks! Like a very soft clock, tick, tock,tick, tock. It's not powered on, feels cold/lukewarm to the touch, the boiler went off at lunchtime so only the machine itself was on to do a weekly backflush. I could maybe ignore it if it was more of an irregular sort of thing but this is definitely as if it has some sort of timer going on, and its switched off, still powered though at the wall. Now then … anyone else 'listened' at all? Why do i doubt it … it's just me then!

@"skylark"#p49682 - unplug the machine, wait 2 minutes. Listen out again. Can you still here it? Are you able to pin point a location in the machine where it's coming from? I've tried putting my ear around it, but I can't hear anything!

Not really. I first heard it when i was reaching for the power plug so i'd guess left hand size as you're looking at the machine. It's a definite regular ticking which i'd not think was indicative of heating up or cooling down contractions. I suppose i'll keep listening for it but as to whether its answerable? Can't say i am aware of it when the machines on but really wasnt aware until yesterday when i thought 'what's that noise' and looking for a clock in the room, why i've no idea cos we aint got one in the kitchen. Anyways, if it gets people listening to their machines then i guess it'll sort itself out soon …

I think mines doing similar thing when service boiler is cooling down. I will pay attention tomorrow.

@"skylark"#p49688 - so, I had to check. Machine was last used in eco mode at 1pm. So it’s completely cooled down, as it’s now 8:30pm. As there are no TVs or noise around now, I went and checked it. And, mate…. You are not going mad! So I unplugged the machine and the noise is still there. I then moved the machine somewhere else, and, to my surprise, the noise is still there. If I am to put a place, it’s the LCC. Just put your ear over it. I can hear quite clearly. The frequency is a tick every 5 or 6 seconds or so. It’s very faint, I can’t hear unless I put my ear right on it. It’s a very similar sound to my wrist watch second hand. Sorry folks, old fashioned guy here, no smart watch… 🤣🤣🤣🤣🤣 Could anyone with an Elizabeth check and report back? Thanks! @"Cuprajake"#144 , what about the Bianca? If you put your ear over the LCC when the machine is cold, do you hear a tick?

@"skylark"#p49692 my son has a stethoscope…. I might play doctors later 🤣🤣🤣🤣🤣🤣

Lelit Elizabeth 'ticking'?

skylark

Yay!! That’s exactly it, I’m not imagining things then.

Just checked again and its been off for some 5hrs now and i can here it from a distance of about 18″, loudest at or around the front top’ish, more central than not. Still ticking, not as regular as before so maybe about to sleep ….. battery operated Lelit Lizzie, there’s a novelty.

Ooh matron …. 😂

Cuprajake

MediumRoastSteam nope not doing that, as I’ll focus on it and end up selling it 😂

MediumRoastSteam

Cuprajake - fair play! 👍

LMSC

Cuprajake nope not doing that

Ok today I kept the machine on(brew boiler only) for about 1hr haven’t heard any ticking, now it’s cooling down, still nothing. Later today I might try it with service boiler on.

I used to run mainly with brew boiler only, but sometimes I did use the service boiler and don’t remember any unusual noises. I am definitely sure I would have been alerted if anything strange was happening. As machines cool down they can tick, usually it’s not regular though and definitely nothing when cold. There are no components in the LLC that can tick,

MediumRoastSteam

I’ll check my machine when I get home tonight. It would’ve been off since 8am. I doubt the tick is related to expansion/contraction of metals though.

skylark

Mine was silent this morning.

Inspector

Ok steam boiler was on and now cooling off been about 1.5hrs, ticking going on about every two seconds but I can only hear it if I put my ear against gauge area :)

MediumRoastSteam

Inspector - mine has been off since 8am. Still ticking away every 5 seconds, but same as @Inspector I have to put my ear against gauge area.

Very strange.

DavecUK

MediumRoastSteam - mine has been off since 8am. Still ticking away every 5 seconds, but same as @Inspector I have to put my ear against gauge area.

Heat and bubbling in the capilliary tube?

Inspector

Surely there shouldnt be any heat/bubbling left after 12 hours :) Will check mine again in the morning before i switch it on.

DavecUK

Inspector After 12 hours?

MediumRoastSteam

DavecUK - yeah, mine has been off since 8am!

Inspector

DavecUK my wife turned the machine on already in the morning I couldn’t check it, but it has been 4hrs since it’s turned off and now ticking like a clock hahaha. I also unplugged it. I don’t get this :)

skylark

Mine hasnt ben on at all today and … no ticking, surprise surprise but tomorrow i expect to be able to hear it from around 18″ distance. Now I’m not claiming to have mega powers when it comes to hearing but its as MRS describes, like a swishing analogue watch . Strange that it doesnt seem to unwind itself for a good few hours after powerdown. It definitely doesnt sound like a boiler or internals cooling down but i suppose that’ll be how things will be accepted …. i’m not too worried about MY machine now that others can confirm my findings. Cant speak for others who may have way more enquiring minds than me ….

MediumRoastSteam

skylark - Machine has been off for 24 hours. Checked just now and guess what? It’s still ticking away, at the same frequency.

Go figure…

MediumRoastSteam

MediumRoastSteam - as reported above, doesn’t seem to tick away when the machine is on. So I turned the machine off (while hot) and tried to hear it out. No ticking.

🤔🧐

DavecUK

MediumRoastSteam Is this off off, or off. Wall socket off (or unplugged) vs switch on machine. I can’t remember if the machine has a DPDT switch or not.

MediumRoastSteam

DavecUK Is this off off, or off.

MediumRoastSteam So I unplugged the machine and the noise is still there. I then moved the machine somewhere else, and, to my surprise, the noise is still there.

I tried both Dave. Off and Off Off. :-)

PS: Looking at some pictures, looks like the machine does have a DTDP (Dual Pole Dual Throw switch) or at least a DPST (Dual Pole Single Throw) switch.
