Why Does my Rancilio Silvia V3 Have 2 Water Tubes?

[fishiesteethies]

I have the short tube going to a seperate water tank because always there was grinds going back into my reservoir , as soon as i put the short tube in a seperate tank the grind no longer end up in my main tank. i switched it up and i always get grinds in the main tank with the small tube

@fishiesteethies Wow -- can't say we have ever had this problem with our demo machine. :) - Kat

[fishiesteethies]

@SeattleCoffeeGear yeah i dont know why, i just new the shortr tube was backflushing water from the boiler, i was getting grind particals in my tank, so i took the tube out and no more dirty water being re located into my cup of coffee, kat! do you think i am using to fine a grind? i always get water back flushing when i pull a shot, thanks Kat!

@fishiesteethies Seriously, this is perplexing our techs, because the water isn't going through the brew head; it's basically cycling through the expansion valve. They were wondering if maybe it's that your expansion valve's seal is disintegrating and that's what you're seeing? If you turn the pump on but don't open the wand to allow hot water to come out and it is just cycling through the overpressure tube, do you still see dirty water? - Kat

[fishiesteethies]

@SeattleCoffeeGear You have spoken to your techs. What is the expansion valve. Are you saying the water that comes out of the small tube does not go to the expansion valve?

Not sure what you mean about turning the pump on, dont open the wand, what is the over pressure tube.

what do you mean?

I dont much about the specifics of a coffee machine yet. or how to trouble shoot it.

i dont know why its doing this.

[SeattleCoffeeGear]

@fishiesteethies The expansion valve regulates the pressure of the water going into the boiler; vibratory pumps produce more pressure than necessary, so this helps release the excess pressure. So this is the water that is being bled off at the valve and being released into the water tank via the shorter tube. The water that is going out via that shorter tube never touches the coffee. - Kat

[fishiesteethies]

@SeattleCoffeeGear I kind of understand, what about when you back flush, and water that comes out of the group is forced to flow back, i notice a steady stream flows out of the short tube.

Is this a different case as to extracting coffee?

Do you have any idea why grinds would be entering my main tank?

Thansk Kat.

[SeattleCoffeeGear]

@fishiesteethies Backflushing addresses just the brew head and solenoid valve, doesn't go into the boiler, etc. However, there is going to be a steady stream coming out of the short tube every time you run the pump because of that overpressure release -- your detergent won't go in there or anything. I'd give the retailer you purchased from a call and ask them to troubleshoot it with you under warranty, if you can. What you're seeing (grounds in the overpressure) shouldn't be happening. - Kat

[fishiesteethies]

@SeattleCoffeeGear thanks kat, how did you learn all this? I will give the person i bought it from a call and its under warranty still so thats good :)

Thanks KAt

[SeattleCoffeeGear]

@fishiesteethies what I don't know from my personal experience, I asked our techs about (we're a certified Rancilio repair center and the guys work on these/troubleshoot these machines all the time), and they provided me answers to your questions :) - Kat

[fishiesteethies]

@SeattleCoffeeGear Thank you for asking your techs about my issue i greatly appreciate this. I spoke to my dealer, i was assured the particles are not grinds, it goes against reason and rationality. I was basically told there must be something in the machine that is

[fishiesteethies]

@SeattleCoffeeGear  returning these particles. I was told to descale the machine or buy a filter for the water. Apparently it should not have effect on the machines functionality! Its funny tho these particles appear when i extract coffee and not back flush?

[SeattleCoffeeGear]

@fishiesteethies Yeah, no idea here. Sounds like their recommendation is the right direction :) Let us know how it works out! - Kat

[fishiesteethies]

@SeattleCoffeeGear i mean the water that comes out of the small tube does not go to the brew head.

[turkeyandwich]

So, does this recycle dirty water into the res when I am back-flushing the machine?

[SeattleCoffeeGear]

@turkeyandwich No -- it is a different circuit. Backflushing is going to be forced through the release valve and end up in your drip tray. This would recycle through if, for example, you turned on the water pump and did not open the steam/water wand. - Kat

[faustas308]

This answers 2 questions for me actually!

[SeattleCoffeeGear]

@faustas308 Great!

[Zamitabha]

solved the puzzle! I was gonna tape the shorter tube so it would dip into the bottom!

[SeattleCoffeeGear]

@Zamitabha Happy we could help :D - Kat

[rudiwells]

short and sweet!

[rudiwells]

@rudiwells (that's what she said)

[SeattleCoffeeGear]

@rudiwells Just like me! ;) - Kat

[robotmotor]

thanks kat i did not use my briville machine for three day i clean it some cocroches come inside the machine but he didnot toch the water its really big problem i call company they kill them and i put duble tape roun the water countainer so he will catch the koklokosh ask gail please a bout that

[SeattleCoffeeGear]

@robotmotor Not sure what you're asking here -- how to keep cockroaches out of your machine? - Kat

[robotmotor]

@SeattleCoffeeGear  yes and see gail maybe she know som idea miss kat

[SeattleCoffeeGear]

@robotmotor We don't really have any good tips; cockroaches don't come around these parts, really, so haven't had to contend with keeping them out of equipment, etc. Sorry :( - Kat

[robotmotor]

@SeattleCoffeeGear thanks kat
