Don't wash any part in a dishwasher.
Don't put the machine in any liquid.

descale regularly — even in soft water areas
Limescale may be white, coloured, even rusty-looking, but it's normally visible.
Phosphate scale isn't generally visible, but it's there, even in soft water areas.
All scale causes overheating, and reduces the coffee maker's life.
So, even with soft water, descale regularly, to help keep your coffee maker in working
order.
Use a descaler suitable for plastic products (all filter coffee makers have plastic parts).
Follow the instructions on the descaler, then fill the water tank , and run the machine
without coffee, to ensure no residues are left.
