First allow the appliance to cool down sufficiently.
- Fill the reservoir with cold water.
- Add the amount of descaling agent indicated on the package.
- Place the permanent filter into the filter holder, not forgetting to put the pot in place.
- Switch on the appliance.
- Once about 2 cups have flowed through, switch off the appliance and let it stand for half
an hour to allow the descaling agent to work.
- Switch on the appliance again. After all of the water with descaling agent has flowed
through, brew clean water through it three times to rinse away any remaining traces of
descaling agent.
