I found this on the boiler lid today. It wasn’t there (about) 4 months ago. Could this be a problem? If yes, how to fix it? Thank you.

    jhf - what water do you use? Looks like calcium deposits, but it might not be. You could remove and refit those, but the fact you are having it on both fittings seems too coincidental that they are both leaking makes me doubt whether they are actually leaking or this is something else, or maybe it was there before and you didn’t notice? Have you ever had anything done to those fittings? Are there signs of the same elsewhere?

      Thanks. I filter the water through a BWT kettle and a Lelit water softener. The last time I had Eliz split was 1.6., I probably would have noticed. I haven’t done anything with the fittings yet, I haven’t seen any signs of water leaks (?) anywhere else. I’ll clean it from the outside without taking the fittings apart and see what happens next.

      Looks very much like 2 leaking fittings with limescale “stalagmites”. Contact retailer if under warranty to cover yourself.

      If not under warranty, remove fittings, clean, refit with 10 wraps of PTFE tape.

        Thank you, Dave. The machine is just out of warranty. I think I can fix it myself :-)

        I cleaned the deposits and will wait to see how it continues. If I wanted to seal the fittings, do I have to do it in these 7 places? Thank you.

          1 and 3 no, they are John guest style pushfit. Push the ring in to pull the tube our. The other areas, yes.

          jhf - you don’t need to apply PTFE on the push fitting connectors where the PTFE tube slots in. Be careful undoing those. It’s truly push fit, similar to a John Guest fitting.

          So definitely not on 1 and 3.

          If you need to unscrew 2,4,5, 6 so you can ultimately unscrew 7, then yes, you’ll need to apply a few turns of PTFE there too.

          I’m no expert: DavecUK can confirm. 👍

          Edit: Dave replied while I was typing. I think he meant 1 and 3. 😊

                Thank you MediumRS and Dave. That will make it a little easier.
