Re: HOWTO: Installing a power-on timer on your S1 (Request)

I'm using the "Econ" LED since it's always on while powered up (at least in my case).

Interesting about the PWM - I didn't check for anything but DC but will next time I'm in there.

I have my Insteon I/O Linc timer working fairly reliably now, but sometimes my S1 fails to turn on or off (due to some interference with my I/O Linc).

Hi All, S1V1 (rotary pump) During the course of some regular maintenance today I noticed an odd behaviour.

I think this is a different issue than what I originally thought. Despite being fully up to temp/pressure, the steam wand releases mostly liquid. I can fill a 20 oz. pitcher with it. Almost as if the boiler is way overfilled. And it might be my imagination but it seems to cycle refills more frequent...

I assume it's the sound of flow through the pump bypass restrictor when the pressure exceeds the 9 bar set point? No? Might be, although it happens with no pressure at the grouphead. In fact, it doesn't happen at all with a blind filter in place which is another clue. Also, on first run it takes ab...

Re: Left side bias on bottomless PF

Do you tamp with the basket in the portafilter? My guess is that your tamp is biasing to one side.

I often get the same thing, despite consciously trying to apply even pressure. Some nutation helps.

Good luck!

The cause of the siren-sound is proximity to the round chassis holes. The cheap fan doesn't help, but it's the airflow through these holes that makes and/or accentuates the noise.

The rotary pump has a built-in pressure bypass valve. (Actually the V2 Mini also has a pressure bypass valve, a rarity for vibe pump machines.)

Re: NoIsE

In my case it dripped for some time before clogging up the drain hole with corrosion. In some cases it might clog before having much chance to leave a drip mark so lack of drip marks aren't a guaranty that the pump seal isn't leaking.

YMMV but if you see drip marks, you have a leak.
