Backflushing

Backflushing your espresso machine should only be carried out if your machine has a three-way valve. If your machine does not have a three-way valve, you will cause damage by attempting to backflush it. Consult your operator’s manual to check if your machine has a three-way valve, also known as a three-way solenoid.

Steam wand maintenance

Despite what you may have read or heard, you must never soak your steam wand. If you soak the steam wand, it will soak the milk residue into the boiler causing what’s known as sour boiler. If this happens, you could be looking at up to $1000 to repair the boiler.

By wiping and purging the milk residue between every coffee, you will ensure that the steam wand is always kept in perfect condition, eliminating the need for further maintenance.
