Something to think about, if the machine is operating properly (no bad parts) a LOW voltage will cause the fuse to blow, VxI=W or Volts times Current equals Watts. To maintain the same heat output, a low voltage condition will cause the machine to draw more power (amps) and it could be enough to blow the fuse. That would be the first thing I look for after making sure there were no problems with the machine.

I think you are confusing things a little here. If you would want to maintain the same heating power with a lower voltage, you would need to swap the heater for one with a lower resistance to get the higher current required to accomplish the same power. This is what the manufacturer needs to do when converting a machine from european 240V to american 110V. Ohm's law; I = V / R.

However, for your specific heater the resistance is fixed. This means that if the voltage drops, the current drops, and the heating power will drop squarefold. A 1400W heater for a 110V system draws 12,7 A of current, because it has a resistance of 8,7 Ohm. If the voltage would to 100 V, the current would drop to 11,5 A, and the power to 1150 W.

Slybarman, just wanted to update you on my thermometer use. I love it! It's made a huge difference in my ability to get a consistent temp on my shots. I was hesitant to spend the money on it but very glad I did. Thanks for the advice!

Still working on the steaming part and I remember reading earlier in this thread that you had purchased the Rocket steaming tips. Are you using any of them? I've read lots of complaints about the larger sized holes of most stock tips that come on the no burn arms. Do you know how big the holes are on the Rocket 2 hole tip and whether they are any smaller than the holes on the Cuadra II's 2 hole tip?

I plugged one of the holes on my tip and did way better on the foam. However, I don't want to continue steaming with a toothpick stuck in my tip. I've been emailing Jim about trying to find a 1 hole tip and he's been looking for me. Seems it might be a difficult find. I took his suggestion to remove the toothpick and keep practicing but I'd still like to find a 1 hole tip or a 2 hole tip with smaller holes. Hence my questions about the size of the holes on the Rocket 2 hole tip.

I've also read that I might do better with a nicer, thicker steaming pitcher. Do you have any opinion on the different shapes and whether they make much difference in the rolling action? I'm steaming around 10 oz of 1% milk and was looking to buy a new 20-25 oz pitcher.

Thanks for your help!

Good to hear the thermometer is working. I definitely think it is a worthwhile option.

The Rocket tips do not have a 1 hole tip in the pack. The holes in the 2 hole tip look to be the same size as the stock tip as best I can tell by eyeballing it.

I made my 4 hole tip into a 2 hole tip using a tiny dab of JB Weld. It is permanent and no issue keeping it clean. I don't see any reason you could not do the same to make a 1 hole tip.

I tried 19g this morning and hit the screen. It won't keep me from drinking it. :) (Click for larger image)

CRUZIE .... I see you are from Ohio. By any chance are you close to Canton? You are the first one I seen on here that is at least in the same general area as I am.

I have two kinds - Vertex and Black Cat Project. I like the cup shape of the Vertex better but the handles on them are stupid (you can't get your finger through).

Hey Rob, I actually live in TN now. Pretty much in the middle of nowhere. I love it though.

an update and question Haven't had a fuse blow since i went to the 10A question.... and new problem. It now sounds like there is water dripping on the boiler.... the spitting, sputtering sound you would hear if you got a bit of water on the hot boiler. There are no leaks though ... I checked. After looking and listening more closely, it sounds like its coming either from the grouphead or perhaps the tube the overflow comes out. Any ideas what this might be? I am thinking a valve or some such is stuck open a bit. Its not drastic, but fairly steady.
