Dolce Gusto coffee maker grows green in corners of water container

[Honu]

I have no problems with descaling the coffee maker but I keep having to brush green growth out of the corners of the water container. The water is changed every day. Any ideas? TIA

Clean and dry the container in between uses, i.e overnight. You are getting what sounds like algae growing in it - if the place it is in is warm, they'll grow more quickly.

My nespresso does the same. Especially in hot weather. I empty mine over night and leave it to drain

Is it in direct sunlight? That might be exacerbating things. Try moving it to somewhere shadier and cooler.
