This is a short how-to on descaling an ECM Giotto.|
Simple Descaling solution: 1 tsp of citric acid per quart of water.(4tsp/gallon)
I get my citric acid from the local home-brewing store. It's used for making wine.
In order to fill the entire boiler with H20, you'll have to take the top off.
Be aware that there is electricity in the machine, don't touch the innards when there is live power.
Some anatomyVacuum Breaker: Opens when the machine is cool,
closes when water begins to steam.
Water sensor: Fine wire connects to it, when water
touches the shaft inside the machine stops filling.
Fill the boilerDisconnect the boiler water sensor wire.
I let it hang over the front of the machine.
Make sure the hoses are submerged.
Open the steam valve (point it at the tray)
Place a rag over/around the vacuum breaker valve.
Water will come out both when it's full.
Plug in and turn on the machine.
Once the boiler is full of descaler solution
-Water will come out the breaker/steam wand.
Turn off the machine.
Reconnect the boiler water sensor.
Turn the machine back on.
If you want to descale the HX as well,
Activate the brew head and allow a cup of water/solution out.
Let it sit, heat up and descale.
I let mine descale for three hours, some do overnight.
