How many members fill the water tank in the machine ?
Do you ever take the tank out ?
I always take the tank out as there are too many electrical / electronics down below.
When I removed the tank the other day I did the ’sniff" test.
With the hot weather, it is not surprising it smelt a little stale.
I remedied this by filling with water and MILTON sterilising fluid.
Just a reminder of something else that needs doing.
I do use filtered water.
