Espresso Machine Maintenance

Cleaning and Troubleshooting

Below is a general cleaning and troubleshooting guide for traditional espresso machines.  Super-Automatic espresso machines are generally run through frequent cleaning cycles and require different cleaning methods.  With proper cleaning and service, high quality commercial espresso machines should last for many years.  Minor problems with espresso machines can often be resolved by cleaning and simple troubleshooting. Refer to your manual for machine specific instructions.

 Cleaning Methods

Porta-Filter Basket Clean daily in hot water. Common practice is to soak filter baskets in hot water and detergent overnight to dissolve deposits.

Clean weekly.  Place a teaspoon of espresso machine detergent into a porta-filter with a solid basket.  Attach the porta-filter to the group.  Cycle the coffee delivery switch (turn on and off a few seconds at a time) until the water drains clean. It also helps to do this cleaning daily without the detergent. Perform this operation only if your machine is equipped with a 3-way electrovalve that backflushes from the portafilter to a drip tray.

Steam Nozzles Keep clean at all times. If necessary, clear steam exit holes with a needle.
Water Softener Regenerate monthly, or as needed depending on machine use and water type.
