- in order to make a food safe descaling solution, dissolve about 1 teaspoon (5ml)* of citric acid to every litre (about a quart) of water. While you are waiting for the citric acid powder to dissolve you should remove and clean the shower screen. Stirring will help dissolve the powder. Place your frothing pitcher underneath the steam wand. Do the following steps in quick succession:
- turn the steaming knob OPEN
- turn the power switch ON
- turn ON the steam switch
- turn ON the brew/pump switch.
- run about 8 oz or 250ml of the citric acid solution through the steam wand.
- turn OFF the brew switch
- turn OFF the steam switch
- turn OFF the power switch
Wait 20 minutes, repeat procedure until the solution is used up.
DO NOT let the pump run dry!
Optional - you may want to run a few ounces of cleaning solution through your group.
Empty the remaining solution, rinse and refill the reservoir with clean, fresh water. Run at least a litre (quart) of water though the machine in order to flush out the cleaning solution.
I installed a lamp dimmer module for pump power, so I can have flow control.
