- Remove the majority of water from the internal components of a traditional heat exchanger espresso machine. To prevent freezing and/or water damage during long term storage or shipping.
- These instructions are available for traditional heat exchange espresso machines with a removable water reservoir and with at least one hose in the reservoir to draw water. It is NOT for single boiler espresso machines or dual boiler espresso machines. It is also not intentional for heat exchange machines without a water intake hose on top of the reservoir nor any direct water connect espresso machines.
Requirements before you start:
- espresso machine, power, sink, two large containers or cups that can withstand high heat.
- Water coming from the machine will be scalding hot! Be careful of steam and splashing hot water during the water removal process.
Draining the heat exchanger and boiler:
- Fill the espresso machine’s reservoir with water.
- Plug the espresso machine into an applicable power outlet and power on.
- Allow the machine to heat to its normal brewing temperature or pressure.
- Place one large container under the brew group/grouphead.
- Place the second container under the hot water dispenser/spout/spigot.
- Ensure that each container will not tip over or spill when water begins to drain into them.
- Remove the lid or cover of your water reservoir.
- Remove the water intake line from the water reservoir. If you have 2 or more hoses, the water intake hose is usually the longest hose or the hose with a water filter/softener attached to it.
- Press the brew button to activate the pump.
- On fully automatic machines with an electronic touchpad that doses the water, please depress the semi-auto or manual button to activate the pump.
- For semi-automatic machines with a single on/off button for brewing, please depress the brew button to activate the pump.
- On manual lever models with a small lever on the right side of the grouphead, please lower or lift (depending upon model) to fully depress the microswitch behind the lever to activate the pump.
- After water stops running from the brew head, use the appropriate brew button to turn off the pump.
- Removal of water from the boiler – there are two types of valves to allow hot water to dispense from the boiler. There are espresso machines with an electrovalve whereby the user depresses a hot water switch, and there are espresso machines with a manual valve where the user turns the valve knob in the open/close position.
Espresso machines with electrovalve for hot water Espresso machines with manual valve for hot water Do NOT turn off the main power switch and do NOT unplug the machine. Turn off the main power switch and unplug the machine. Depress (and usually hold) the hot water switch/button until all water depletes. This should not take more than 30-45 seconds. It is important to not exceed 45 seconds as the machine is still on and a lack of water can damage the heating element. Use the appropriate knob to open the hot water valve. Since the machine is powered off, there is no concern for damaging the heating element. The pump will kick on to refill the boiler. This is ok. Once the water has ceased to exit the hot water dispenser, leave the hot water valve open to allow water to evaporate during storage or drain during shipping. At a maximum of 45 seconds, shut off the power switch and unplug the machine. Open steam knob/valve to allow the remaining water to evaporate during storage or drain during shipping. Open steam knob/valve to allow the remaining water to evaporate during storage or drain during shipping.
- Your machine’s boiler is drained. Some water always remains in every used espresso machine. The above process removes as much water as possible.
- For shipping, package in original packaging exactly as packaged when you received the shipment. Plastic bags need to be placed over the machine to avoid scratching from shipping. All loose articles, including but not limited to portafilter handles, baskets, scoops, etc must be secured to avoid cosmetic damage caused by the movement of these items.
- The espresso machine box MUST always be placed into a larger double-wall corrugated box with at least 2″ of foam or similar protection placed between the outer corrugated box and the espresso machine box.
- If receiving a drained machine, re-prime as per the instruction manual
Long term storage notes:
- If possible, do not store where temperatures will be below 36 degrees F or 0 degrees C.
- When taking a machine out of long terms storage, re-prime the espresso machine as per the instruction manual.
