Ascaso In Tank Rechargeable Water Softener / Particle Filter

This is a small insurance price to pay! Softens your water so that less limescale is built up inside your espresso machine – this is very important for semi-commercial machines with heat exchangers as well as many other electric pump-driven espresso machines.


  • Resins are rechargeable for up to 6 months – recommended to recharge at least twice a month with salt OR every 24 liters of water., whichever is sooner.
  • Replace the unit every 6 months to avoid mold, fungal, and/or bacteria buildup. Replace sooner if the unit does not allow water to flow through after a recharge and after confirming the electrical pump does intake water through the hose without the softener
  • Can be used in all pump model espresso machines that have a water intake tube in the espresso machine’s reservoir.
  • This can not be used in espresso machines with direct water/plumbed in connections or where there is a bottom feed of water from the reservoir (meaning water exits through the bottom).
  • Measurements (approximate and subject to slightly change without notice): H 4 1/8″ x W 1 3/4″
  • Canister Height: Approximately 2 inches and extension about 1 inch.


  • For Rancilio Silvia’s, the connection is loose. You can use a tie wrap to secure it to the hose. As an alternative, you can use the Lelit water softener (MC747).
  • The resins expand after getting wet.
  • Instructions are available with purchase (please email when you receive it or request it during checkout in the comment section).
  • Warning: Upon receipt and use, please make sure that the canister does not leak resins. Sometimes screen breaks or moves during shipping (even after being well packed), and resins will fall out).
  • Please note that water softeners are not returnable under our return policy.
  • The water softener must be inspected for damage and regenerated with salt prior to use.
  • Replaces NE454 NE.454
  • Replaces 7374012 Bezzera Water Softener – BZ02 & BZ07

      A I'm an amateur with limited experience, though I've had my machine for 9 years with no (apparent) evidence of Lime disease(?) I have not descaled, so much has to do with the quality/make up of the water (and your pipes). I suspect those numbers are available. Downside to this device is that it may put extra strain on the motor, so if you remove it, I would put a little filter (I just removed the gel from the acaso and use that) at the end of the hose.

      A When placed in water the material expands and fills the entire filter.

      Sorry, we do not recommend this because we are unsure of any damage that may occur.

      Please make sure to recharge and then rinse the water softener before use. The water softener needs to be filled with water before insertion.

      Best is to try to stand the water softener so the hose is vertical, but this is not always possible.

      Only if you have the clear vinyl hose that came with the machine. This hose attaches to the adapter on the bottom of the reservoir and the other side connects to this water softener.

      Although we can not guarantee it as we do not carry the Gaggia Classic espresso machine, it should work as reported by some of our customers.

      Yes, it should fit through the opening on the top of the reservoir. Please make sure to connect to the longer hose first before dropping it in.
