Re: SUNBEAM 6910

Even so, how easy would i be to inflict rust like that?
And who would use steel wool on a relatively clean surface?

It isnt necessary for someone to have used steel wool. If they use any one of many types of rough scouring pads that are available on the market, it is possible to transfer carbon steel or iron particles from one surface to another, e.g. If they used a scourer pad to clean up a stoves hotplates then used this same pad to remove coffee stains or whatever from the espresso machine.... Its easily done and effects the s/s surface in a very short time, typically overnight is long enough.

It would be very hard to imagine that the actual s/s alloy is at fault but not impossible of course. Sometimes if the s/s finish is a little too roughly finished, it can allow foreign matter to attach and collect in the very small crevices and thereafter encourage the onset of corrosion. Polished s/s is a much better proposition in this regard compared to the various "satin" finishes as there is simply nothing there for particles to become entrapped.

Re: SUNBEAM 6910

Never experienced these fine metal shavings you speak of. Id ring sunbeam about it.

I believe the pump is much softer than the silvia when a proper shot is pulled. Loud to start then lowers to a quiet hum

Re: SUNBEAM 6910

Bit off the topic but still rust related... When i opened my EM6910 i saw the note about water dropletts inside the bag but it was all dry. When i turned it on for the first time (with a full tank) the pump ran for 5 mins with no sign of water comming through the group. I switched the hot water on and that seemed to work.
After waiting 15 mins i tried the brew switch again and after about 1 minute the first dribble of water came though the screen into my cup. This little bit of water was dark brown (rusty?) and looked to contain tiny black particles like fine metal shavings. I ran about 3 liters through and by then the water was nice and clean.

The next day after filling the tank in the morning the pump ran again for five mins before water came through, and again metal shaving things in the cup.

Since then the water has always come through fine and I have had no problems with the water flow from the group. The pump is very loud and sounds sort of scrapey, but i have read that these machines are loud. Somtimes when i am flushing machine after cleaning i can still see these fine particles. They are finer than coffee particles and sort of grey/black in colour.

I am very happy with the performance of the machine, and was just wondering if my experiences were normal for EM6910.

Re: SUNBEAM 6910

But if the side in question is hard to get at, is it likely the cleaners have touched it?
They need to be asked.

Steel wool is something Id only use on a stubborn stain.
I can only go by my machine, it gets splashed with water and the occasional bit of spent puck but it only needs a wipe and dry and never looks like it needs any sort of full scale assault.

Re: SUNBEAM 6910

Gday Rolley,

Most commonly in this sort of situation, the culprit usually turns out to be the use of "steel wool" or something containing carbon steel, as a stain remover. Maybe your cleaning personnel use these sorts of products as part of their general cleaning regimen and the use of same on s/s leaves small deposits of carbon steel behind on the surface of the s/s which then immediately starts to both oxidise and encourage galvanic corrosion.

Id suggest that this is the most likely cause in your case and maybe a chat to the personnel who clean this area is in order so that they understand that such products must never be used on the espresso machine. Its a fairly common situation and usually just needs a bit of education to overcome....

Cheers,
Mal.

Failing that, yell loudly at everybody that uses the coffee room with wild accusations of sabotage! Its probably totally inappropriate but can be quite cathartic ;D

Re: SUNBEAM 6910

...I assumed that it came straight out of the box that way...hence my comment about sunbeam replacing it!

Re: SUNBEAM 6910

haha.. yeah! ;D baby everything, Ive got tons!
The stuff on top feels smooth as... a babys bottom.. and the stuff on the side actually feels raised slightly, as if its a build up rather than eating away at the metal.
Hrm..
:
Well, Im knocking off now, Ill pick up that esteele tomorra on lunch and give it a go!

Re: SUNBEAM 6910

The rust on the cup warmer look different to me Rolley - like its been rubbed with an abrasive pad. Good luck with the esteele - if it comes off, I suggest you try protecting it with something like baby oil (am guessing from the pic you have some of that around).

Does the surface feel pitted?

Re: SUNBEAM 6910

Yes indeed it was. And theres also a disclaimer saying things can be wet because they are tested with real water or something.. damn.. I cant even remember what that was written on, it only just sprang back into my mind now.. I think we threw out the plastic bags so I cant check them for moisture..

Re: SUNBEAM 6910

Was the unit inside a plastic bag in the box?

Re: SUNBEAM 6910

Hrm not sure if the cleaner would have sprayed anything anywhere near this side, the machine is actually on the Left END of a bench (so no one could have sprayed a bench next to where the rust is).. and theres a tall fridge about a foot or more away on that side too... To get the photo I actually had to pull the machine to the front of the bench, and turn it around!

The cleaners usually just empty the bins, do the floors etc, I think the policy is that the bench tops are our own problems to clean.  :-/

But, nonetheless, I think youve got a good point, so Ill definately keep it in mind.  Also, theres some on the cup warmer too, but no where near as much.. hrmmmm.. it really does smell like rust too..

Ill see what happens with this esteele

Re: SUNBEAM 6910

Agreed- looks like corrosion by something nasty sprayed from front to back and wiped at base to me.... :-/

Re: SUNBEAM 6910

In all honesty it looks to me as though your cleaning person has sprayed around it and its picked up some sidespray, with the bottom part being brushed by the cleaning cloth. There are some fairly corrosive cleaning chemicals out there if they arent mixed correctly.

I wouldnt mention that to Sunbeam though.

Re: SUNBEAM 6910

Am no engineer Rolley, though from my past trades experience, it reminds me of scenario where:
grinder is used on steel nearby
sparks hit the surface (in this case your machine)
they burn the polish/chrome and after a while,
rust appears
