Service | How to Drain the Boiler

If you need to transport/ship your machine or are planning to store it in an area where it could possibly freeze, it's important that you first drain the boiler to mitigate any damage from leaking or freezing.

Here are some general guidelines for how you can do this on different machines, but please refer to your user manual's instructions and rely primarily on its directions if these differ in any way. Not sure which type of machine you have? Your user manual should reference this.

Semi-Automatics without Heat-Exchanger

Please read these instructions in their entirety and let us know if you have any questions prior to beginning the process.

  1. Turn the machine on and prime the boiler (please refer to the machine's user manual for specific instructions on how to do this).
  2. Turn on the steam switch and let the machine get up to steam temperature.
  3. Bring the machine to the sink and tip it onto the side with the steam wand.
  4. Open up the steam knob all the way and allow the machine to push all the water out of its system.
  5. When there is no more water coming out, close the knob and pack your machine for cold weather transport.

Semi-Automatics with Heat Exchangers

Please read these instructions in their entirety and let us know if you have any questions prior to beginning the process.

Proceed with Caution!
Your machine must be heated to its normal steaming temperature in order to properly drain the boiler, so keep in mind that your machine and water are at scalding temperatures. Please take care -- remember that the splashing water & steam during dispensing is scalding and will burn.

  1. Plug in your machine and bring it to its normal brewing temperature/pressure. This may vary from machine to machine, so refer to your user manual on how to do this.
  2. Place 2 large, tall-sided containers -- one under the brew group, one under the hot water dispenser -- that are securely and solidly supported so they won't spill when water drains into them. Keep in mind that the combined capacity of the two containers must be greater than or equal to your boiler's capacity.
  3. Remove the top of your water reservoir and its water intake line.
  4. Engage the pump by turning on the brew button.
  5. Run the machine until the water stops flowing from the brew head.
  6. Turn off the brew button and the main power switch.
  7. Open the hot water dispensing valve and then run the machine again until water stops flowing from this valve.
  8. Once water no longer comes from the valve, turn it off. Your boiler is now drained.

Superautomatics

Please read these instructions in their entirety and let us know if you have any questions prior to beginning the process.

Proceed with Caution! Your machine must be heated to its normal steaming temperature in order to properly drain the boiler, so keep in mind that your machine and water are at scalding temperatures. Please take care -- remember that the splashing water & steam during dispensing is scalding and will burn.

  1. Plug in your machine and bring it to its normal brewing temperature/pressure. This may vary from machine to machine, so refer to your user manual on how to do this.
  2. Place a heat-proof, tall-sided, 20oz.+ container under the steam wand. We recommend a heavy plastic container or one with a handle, as the draining water will be scalding hot and you will need to touch the container.
  3. When the machine has reached steam temperature, open the steam valve.
  4. While the machine is steaming, remove the water reservoir.
  5. When water or steam no longer dispenses from the machine, close the steam valve.
  6. Turn off the steam button and the main power switch. Your boiler is now drained.
