Lelit bianca hot water outlet not working

Emc2

Would be grateful for advice. I posted in the other forum and noticed that many members have moved to this one.

I initially had issues with the y hose that was damaged and leaking. I replaced this and the machine is working. However the hot water spout isn’t. A small amount comes out and then stops.

Emc2 is the steam wand working normally, plenty of steam? What steam pressure is showing on the gauge and steam temperature in the LCC?

Did you descale it recently?

Emc2

The steam wand is working normally. Pressure is between 1 and 1.5 bar. Temperature is 119 degrees

It’s a used machine that I recently purchased. The person I bought it from has not descaled it and has used only filtered water

Emc2 It sounds like the machine has a blockage specifically in the water wand.

I asked the questions, because I didn’t want you to work on something that might not be the problem. It could have been.

machine going into standby, drawing a little water is enough to cool the boiler enough that the vac breaker pin drops and it is depressurised, only a dribble coming out
if the gauge pressure matches what should be the correct temp, then that indicates the gauge and temp sensor are not faulty
if the steam comes out good and strong and is maintained pressure doesn’t suddenly drop away, then theres no sticking vac breaker.

So we’re left with the blockage.

remove the perlator from the bottom of the wand, is it blocked, does water flow well without it? = no
remove the wand from the valve, does the water flow well now = no
then it might be blocked at the point it exits from the boiler, or in the valve body itself
try descaling the service boiler, and try to run water out of the steam want a bit when descaling.

If the above doesn’t fix it, then you will have to start removing pipes…..which we can cover later.

Thank you for your help Dave. It was a blocked wand that was completely filled with crud. I tried descaling the machine and it spat out fine sand like material. I was surprised to see the extent of scale considering the machine is only 20 months old. I suspect the person I bought it from used hard water or didn’t replace the filters regularly.

Emc2 Often people are unaware of the quality of water being put through the machine….so it’s always best to not discount limescale as a potential cause of problems.

This is a useful thread. I have a Bianca that is plumbed-in with a BWT filter, but I worry that, even with the filter, it’s going to need descaling at some point. It’s good to know what to be on the lookout for.
