When cleaning the steam wand after frothing milk, wipe it with a wring-out wet cloth. Only use a damp cloth to clean the main body of the coffee machine.
Before frothing milk, check if there is still clean water in the water tank. If not, release the pressure first before refilling with water, then proceed with milk frothing.
If there is remaining water in the coffee machine, you can pour it out from the water inlet after all steam has been discharged, or drain it from the water outlet by running a coffee brewing cycle.
