Subject: Problem with the ECM Techika Profi II
 

Im in search for other owners of the ECM Technika IV Profi switchable with rotation pump. I have had my machine for a year now, and I really think I have a problem. When I see other ECM machines - even the identical without rotation pump and switchable levers, The steam pressure is much more intense than on my machine. The machine is born with a 2 hole steam head, and even though my  pressure gauge is at 1.5 which is max pressure, I can hardly rotate my milk if I use a milk jar for a double latte. Does anyone else have this problem with this model??

It really irritating and I don't understand why my pressure has to be this low? As I say - other machines I've tried have much higher pressure.
Because of the lower pressure, I have a hard time getting my milk correct for proper latte art creation.

Hope someone here can help me!

Best regards
Steen

Your boiler pressure is more than high enough to steam milk.  In fact, it's probably too high.  My Rocket Evoluzione has the same size boiler and I run a maximum pressure of 1.2 bar.  Don't get boiler pressure confused with brew pressure.  Brew pressure is typically 9 bar, which is independent of boiler pressure for steaming.

How much milk are you trying to steam?  And, what type of milk jug are you using?  If you're steaming a large quantity of milk, then you want to try a 4-hole steam tip.

Hej Steen,

Finally another Technika owner! We seem to be few and far between.

In any case, I have had my Technika for about four months and have not made any adjustments to it or even opened the case. The PSTAT came preset at 1.25 bar and the pump at 9.1 bar. I have the rotary pump, switchable model, like yours. I think the only difference (besides mine being 120v) is that mine presumably has boiler insulation, while yours has the inside frame insulated.

Like yours, mine also came with the two hole tip. I had an Oscar before that, which I had retrofitted with a Silvia 1 hole tip for better control, so it took me some practice to steam with the two hole tip. I have noticed you need to tip the steam wand up at a pretty dramatic angle to get the milk spinning, or you can point it straight down and just put it in the middle of the milk, though this is less consistent. My steaming procedure on the Technika is this:

1) Pull chilled pitcher from the freezer

2) Fill with milk, or in my case, a shot of Splenda, 1/2 water, 1/2 half and half (low sugar diet)

3) Place tip about 1cm below the milk in the upper corner of the pitcher near the spout, with the pitcher slightly tilted

4) Open lever to full

5) Wait for milk to start spinning, which gives me a chance to adjust the placement of the tip, THEN pull back a bit to start introducing air into the milk

6) When the pitcher starts to get warm, I push the tip back into the milk only about 2-3cm and spin it until it is uncomfortably warm, then immediately shut the steam off.

Another thing I should mention is that I purge the moisture from the steam wand before frothing the milk, then wait for the Pstat to complete its cycle, before beginning. If it is a problem with the machine itself, my only suggestion is to check your water hardness because of possible scale. Is yours plumbed in? Do you use a water softener?

Honestly, yours should be a beast compared to mine--Pstat set 1/4 bar higher, and higher voltage Euro heating element.

I've got the vibe pump version.  My steam boiler runs around 1.4 bar.  I have enormous amounts of steam and can easily whirlpool the largest steaming jug I have.  I tried both Espro steam tips but ended up moving back to the stock two hole because it allows me to produce really silky smooth milk.  Have you given the wand and or the steam tip a thorough cleaning?

Hi Markarian and kwantfm. Thank you so much for your answers.
I have been in touch with ECM in Germany who have been very helpful. They advised me to try and empty the boiler by warming the machine up, then switching it off and emptying the water out through the water dispenser arm. If I got more than 0.9 liters out, my tank had been overfilled earlier somehow which would result in lower steam pressure. I got 1 liter out of the boiler and it seams that it has helped some. Im not completely satisfied as I have tried 2 other ECM technika machines  with overloads of steam pressure, but it has helped some.

Markarian - I would be so happy if you could send a video showing your steam pressure and reachable votes speed in a video so I can see how far off I am. Im using the 2 hole tip - tried a 5 hole because I was told this was the problem, but forget it - its just introducing too much air, and I can't control it the same way as the two hole version which gives me a much more smooth result.

Surprising to hear that we are only a few ECM techinka owners.. Beside from my small problem with the steam pressure which is definitely not standard, I love this machine. It beautiful, smooth in operation and very strong and stable.

The very best regards
Steen

Maybe the steam wand or tip are clogged, if the wand is a no burn maybe the inner silicone tube is to long and blocking the steam tip hole. Try draining the boiler again as recommended by ECM, if you get more than 0.9L of water maybe the boiler fill sensor is scaled or needs adjusting.

I the boiler is overfilled, pull the level probe and check for scale. But remember that the water in the steam boiler holds more thermal energy than the steam above the water, so too low of a water level would make for less steaming power than too high. Still, if you are not getting a lot of wet steam then overfilling is probably not the problem. With the boiler set at 1.5 there should be plenty of steam, IF the gauge is correct.

Pull the steam tip off and see what kind of power there is in the steam (do so carefully). if that seems low as well, it could be a problem in the valve. At that point you might want to trace back through the steam path and check for scale or other obstructions.
