Yesterday I back-flushed my Silvia with Cafiza, then pushed on my "off button" in the wall socket (Automatic time ON@6:30/OFF 17:00) and then nicely wiped off the machine.

In the cleaning process I (accidentally) hit the steam pump button and it flipped on...which I didn't notice, because the machine was off...

This morning I hear weird noise in the kitchen...oh shit!!! Water on the floor...Tank empty...pump was cycling on/off...for 20 minutes!!! and i could not figure out how did all the water ended up on the floor, since it returns into the tank?
Have you guessed it yet?
It "relieved itself" through the release valve into the tray...
It returns water from full boiler back to reservoir, but spits out a bit at each shut-off...

So I  filled up the tank, primed the pump and WOW, it works...believe me I felt like an idiot...

However: Could the pump have gotten a little damaged? Considering 20 minutes of DRY run...on/off?
Should I start to look for a new PUMP?

TIA

If it's still working then I wouldn't worry too much about it, they're easy enough to buy if you eventually need to replace it.

Yep, what he said LOL, if it is still operating properly then it most likely is OK. The biggest damage that most machines get from running dry is overheating the heat element, it can either melt and destroy it's self or even only get hot enough to crack and allow water to get to the electrical components. Sometimes the machine will still heat but it will blow the ground fault circuit on the outlet or you may feel shocks from the machine, in either of those cases, the element is damaged and needs to be replaced. If it does not trip the ground fault circuit and you do not feel shocks, most likely you are OK.

I was worried about the pump most of all, because pumps don't like to run dry, if I understand Silvia's working and design, I basically can't damage the heat element, since the input/output are on the top of the boiler and if there is no water supply coming in, water will not come out...leaving the boiler full.

Those of you that know Silvia, do you think that's correct?

Good safety...if the output was on the bottom, I think I could sell it to scrap yard.

I can see a disaster if there is no water in the boiler, because I'm not sure the PID will cut off heating @208F/98C to which I have it set to....(I wonder what the PID does in a half empty boiler, making steam/pressure, would it cut out before burning out?)...Jonr, where are you?

I have read stories about burned out elements...mostly due to over calcification or over steaming...

Well, so far the pump still works and the replacement cost 25 euros, not a bad punishment considering...

I rebuilt a Sylvia, and yes if the heater is on for steam, it will boil the boiler dry and burn the element. It happens all the time. http://coffeegeek.com/images/54891/caniuseitagain.jpg

Thanks for the link, I read it 6 months or so ago, while researching forums for info on Silvia...

Very informative thread, especially when you had to discover 1st hand all there is to know about Silvia...

.... fortunately, I never steam;-)
