Hi. I recently got some new cups, which are black inside rather than my previous white ones & noticed some white flecks in the cup when I was drawing some water from the hot water wand on my Synchronika today.
I don’t know if it’s carbonate sediment, something else or even if it’s indicative of more serious scaling within the steam boiler. It might even have been happening for a while but only noticeable with the new cups
I usually draw a cup of water from the steam boiler whenever I’m steaming & every couple of months I flush the steam boiler with a tank of zero water. I did about 4 flush cycles today, but still had these flecks afterwards.
My domestic water is pretty dam soft so I’ve been remineralising zero water with a mix of Epsom Salts (0.74g) & Potassium Bicarbonate (0.3g) in 5l water, which from my calcs & drop test @ 25DegC gives a GH of around 60-70 & KH of 40. The last drop test I did on the water from the steam boiler a couple of weeks ago showed hardly any increase in GH or KH @ 25degC from the water I’ve been putting in.
I removed the shower screen & also drew some water from the brew boiler, which set to 94 DegC & there weren’t any flecks in that; so it does seem isolated to the stream boiler, which is set to 129 DegC
The machine is 2-years old & hasn’t had a descale since I bought it; as well, I didn’t have any reason until now to think it might need one & also I was really sure of the best way to do it. I’ve no other concerns about the machine & it doesn’t seem to be working any differently to when I first bought it.
So I thought I’d put a shout out to the knowledgebase here to see if you think there is a cause for concern & if the are any pointers you can give on next steps I should take. Thanks in advance
