Hey all,

Woke up this morning to my leva having the usual `AL. 11` error, which usually tells me to fill my tank.

After doing so, typically I expect the leva to make the usual pump sound and then a click of an element and the temperature begins to rise. Unfortunately, this morning, this did not happen. It’s just stuck at 25c. All other elements appear to be functioning properly.

@DavecUK Perhaps you know of the issue? What should I do?

Thank you all!

 I tried checking the manual, and it spoke of taking the top off the machine to reveal the boilers, and then to press the little red button on top. I see no button except a bunch of wires.

```
If a boiler fails to heat, the machine has 2 resettable limit stats: Unplug machine and remove either upper or lower access panel to reset the relevant limit stat, by pressing the little red button in the centre. These are on the top of both boilers. If the problem recurs, contact your dealer for advice.
```

Currently, maximum annoyed. Caffeine headache and a machine that’s less than 3 months that has a non-functioning boiler….. 😠

​

Also after refilling, the A11 signal went away. Also, if I pull the lever, the pump still works and is able to pull water from the tank.

The issue has been fixed. Don’t know how this happened, but at the bottom of the boilers are the electrical connectors. One of the boiler’s electrical connectors was out of its socket. After reconnecting the connector, everything worked again.

I’d say to those coming from the future, if you run into the issue that your boiler is not working and the panel is showing heating is on, try these steps.

First take the right side panel off to reveal the electrical board. At the back there are two black SSR(Solid State Relays) that regulate the power to the boilers. There is a LED on each of the SSR’s. They should be on when the element in the panel is on. If these LED lights are on, then that means the panel is trying to regulate the power of boilers and everything on that digital end is working. The next step I would suggest involves turning the machine on its side and taking the bottom panel off to expose the boiler wiring. Hopefully the issue is that one of the jumpers has come loose and is not connected. If it is connected and the boiler is not working, then unfortunately you’ll probably have to contact ACS about your issue.

I’d like to thank ACS(Paolo) for his quick response early in the morning. He greatly helped with the debugging process.

I’d also like to mention that the pressure knobs on the top of the boilers can be Black!

    @IridiumBlackberry

    We are glad the problem is fixed. Well done.

    Did you take photos or video the debugging process ? It will greatly help every one with troubleshooting and debugging in the future. Thx

    Yes I did, this forum doesn’t seem to support direct upload. Can someone recommend a service?

    I didn’t realise, we can. There are two possibilities.

    One is via youtube without publishing (private). You should be able to share the link here.

    The second is upload on your Google Drive and share the link.

    @DavecUK may be able to suggest an alternative

    The limit stats can be white with a black, red or grey red button, black with a white button, black with a red, white or grey button, or grey with a red or white button. I’ve seen all combinations in my time.

    Glad it’s sorted, I only just settled down with my first coffee to try and help with the fault-finding….but I see you have already fixed it. This post really highlights 2 very important issues.

    If the machine is recent (this goes for any coffee machine), transportation can result in problems during the first month or so…loose wires, arcing connectors (loose but didn’t quite drop off) etc.. Always during the very early days, assume something simple has come loose in transit. In the case of a leak, something wasn’t fully tightened. This sort of problem can be fixed in minutes. Things like pump, boiler or main board failure are much less likely to be the problem…Occams razor. I always try and comission a machine for the first time with the case off, or the top off, so I can observe it come to life.

    It’s super important to always contact ACS first for support…when posting always state you have contacted ACS for advice, but would appreciate any insights others may have. If this isn’t done and your problem is solved on the forum, as you did exactly what I would have advised (and explained limit stats are not always the same colour), ACS don’t get a clear picture of user faults and issues, both long term and short term after delivery.

    I’m very keen for ACS to fully appreciate and understand every and any issue with the Vesuvius Evo Leva as part of continuous product improvement (build) and either a better manual or FAQ for “faults”/issues on their website. To not have a reliance on other users being able to help people with “technical faults”, improve their product and ensures it remains a great product, whilst still being extreme value for money. Hence, I’m very glad you informed ACS, as your first move.

    P.S. The Vesuvius Evo Leva although complicated in what it does, is simple in terms of fault-finding and fixing. It’s largely modular and compartmentalised, so access to the various modules is easy, as are most repairs.
