MediumRoastSteam I look so stupid after reading your how to ! 🤦😂

MediumRoastSteam

dfk41 once a week or more, draw off say 300 to 400 mls

3 times a week a cup each time to be safe, if not a cup at the end of steaming for the day.

MediumRoastSteam

I flush the boiler of my Elizabeth every 2 months! 3 times a week is over the top!

Honestly @dfk41 - drain the boiler (via the hot water tap) once a month and that should be enough. That would exchange the saturated water in he steam (service) boiler and exchange for fresh one from the tank.

LMSC

MediumRoastSteam 3 times a week is drawing a cup.

Please remember, at least the first two batches of the owners’ steam boiler hot water flush cannot drain the water 100% - unlike Minima. The pipe length inside the service boiler is about 70% from the top of the boiler. So, a monthly full flush will not drain the boiler completely.

I do not remember how much the service boiler will fill. I remember (if I remember correctly), the full flesh on our service boiler always drawing about 850-900 ml water from the hot water tap.

This was corrected in subsequent releases. That’s why some of us installed a drain valve at the bottom of the service boiler.

Hope it clarifies.

Edit :

I agree, a regular full flesh is will work very well.

If you want to go further, after draining and before turning the machine on again, fill the tank with pure RO/distilled/zero water, without any added minerals. It’s a bit more of a faff, but it does help to keep TDS low in the steam boiler.

The best way really is monitor the TDS on your steam/service boiler and go from there.

LMSC

MediumRoastSteam Absolutely. However, TDS is not as helpful , IMO, as it could contain anything. A drop kit measuring GH and KH will be super helpful. It won’t still tell you when did scales started forming. But, you get an idea.

I test when ever Indian full flesh from the drain valve.

It’s helpful to determine when you need to refresh your steam boiler for sure.

I.e.: if your input water has a reading of 40TDS at room temperature, you then know that if your service boiler water has a reading of 200 TDS at room temperature (yes, you need to let it cool down) it’s time to refresh it.

You don’t need a GH or KH for this. But you can use it, of course.

LMSC How do you measure how much water is consumed ? I can’t judge looking at the water tank.

Weigh the milk jug before and after the steaming - difference in weight = weight of steam added (and since it’s water, 1 ml = 1 g)

MediumRoastSteam Yep - after purging and getting to dry steam. Which adds another 10 - 15 grams of liquid.

For what it’s worth, here are some TDS figures from my early production Evo (S/N #25, roughly one year old) using exclusively water from my Osmio Zero with the ‘remineralisation’ cartridge after making an total of around 200 small lattes, and flushing roughly one cup on water (slightly less than 100g/cc in effect) after each of these drinks -basically stopping when what comes out of the water wand becomes largely steam :

TDS of the water in the tank: 36 (it varies between 30 and 40 depending on the day), measured at 22°C (still with the original set of filters)

TDS of the water from the water wand: 55, also measured at 22°C

I’m far from a water expert, but these numbers seem OK to me, at least for now.

LMSC

JahLaza I thought forking out for an osmio would save my machine! Good thing I don’t steam too much I spose

It’s nothing to do Osmio Zero. If we steam, let the minerals settle and do not recycle water, the scaling will kick-in.

Eiffel Drawing a cup after every steam works well, so far. I draw a little more every time, besides quarterly flush.

The service boiler stat over 14 months are:

The TDS range is 60-70,
temp range is 19-24C,
alkalinity range is 40 mg/l - 48 mg/,l and
the hardness range is 7 mg/l - 20 mg/l

On the Elizabeth, the purge was 4g of water.

There was a 21g difference in weight between the weight of the milk jug before and after steaming. So, in total, steaming 250g of milk drew 21ml from the boiler (or 25ml if counting the initial purge).

Edit: I tried again, this time purging the wand properly rather than trying to keep the steam inside an cup! I the difference was 12g, more in line with what I remember recording in the past. I could only assume the other 9g of water would therefore be part of the initial purge.

Don’t forget air weighs more than water

I now know why my lungs feel heavy. 🤣🤣🤣🤣👍👍👍👍

CoyoteOldMan

MediumRoastSteam That explains why my head feels heavy…

CoyoteOldMan

First steam of the day:

Boiler at 125 °C, 2-hole tip
185 grams of milk
Purge: 16 grams (+ a bit in the dry towel - but I’m not going to weigh the towel!)
Added steam weight: 28 grams
Total water drawn: 44 grams

LMSC I’m watching “The Strain” at the moment… if you have seen it, I think you’ll understand how my brain interpreted the .GIF at first sight. 😛😂🤣😂🤣

CoyoteOldMan No, I haven’t seen it 😂
