Hey all,

I've recently gotten a Crossland CC1. It's great, but "white slime floaters" keeps showing up in the water tank. I use only filtered water, and the tank is refilled about once per two-three days. The first two times this happened I removed the tank, scrubbed everything clean, and replaced. The third time (now) I'm wondering what's going on, perhaps :

1. I need to remove and clean/dry the tank when refilling
2. My water is funky and has bacteria
3. Water filter is old
4. Odd backflush coming in from the feedback hoses (I see one input and one output hose going to the tank, but surprisingly water occasionally comes out of the output hose--I figured it was to output air)

Any thoughts welcome, picture attached

How often do you normally clean the reservoir?

Never had that happen in the 2 years I've owned my CC1. I just add fresh water every other day or so and take the tank out to clean once a week. The metal tube into the tray is backflush, the two tunes in the tank are intake and the relief tube.

You must first identity the floaters before you can determine what to do about them. Could be lots of things not on your list. Pick some of the stuff up and swab it onto a piece of white bread and check it every day for, umm, interesting things that weren't there earlier.

Funky water is easy to test: put some water in two large glass jars, leave on the counter and put one in the fridge. Do you see floaters?

Try using bottled water for a few weeks.

What is your water source? What sort of filters are you using? How often have they been changed? Clean the filter housings? Etc.?

Good replies!

I currently clean the tank about once / week. The tank is a PITA to get out (I've got to move the machine then wiggle it out), but I'm thinking that more removal and cleaning is the main need. I've let a water cup sit on the counter already, it only got dusty so the issue is likely with the machine/tank. I'm using a standard brita pitcher, and I just replaced the filter this week to see if it helps this problem.

Very interesting. I wonder what's different between us, this is my schedule too

I stopped using Brita pitchers, test showed the filters useless and not filtering after like 3-4 weeks. I tested mine and found the same thing and it was no different than our fridge water. Pry even shorter life if straight from tap here. My fridge filter goes months of filtering no prob.

Are you using the bottomless basket, if you are I wonder if your getting some spritz/channeling shooting into the tank? If not, not sure what caused that. I'd do as above and test the water to see what's in it. If I leave it  for a week it'll get funky, but so will a bottle of water that's been opened, or a tumbler, or cup of water when I've left it out.

I encountered a similar problem on Silvia, after about a month of adding/topping off water to the tank, (using good quality bottled water) one day, by chance I reached in the tank and discovered the tank was "slimy". Invisible to eye, but walls a bit slimy...

I stopped topping off, now I go to minimum ~2" of the bottom and I fill.

I wash the tank with dish-detergent once a month and never had a problem since.

I think that the return hot water could contribute to growth of bacteria-slime...
