skylark - 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 - 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 - 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 , what about the Bianca? If you put your ear over the LCC when the machine is cold, do you hear a tick?

              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.

                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.

                  Inspector 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,

                    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.

                    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 :)

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