Profitec Pro 400: Draining the Machine

Use this guide to drain your Pro 400's group head and boiler. This is an important step to perform prior to your machine or performing repair and/or maintenance procedures.

Tools Needed:
- Measuring cup (4-8 fl. oz.)
- Pitcher (at least 32 fl. oz.)
- Towel(s)

*NOTE: If your machine fails to power on or fails to heat, skip to the end of this article.

1. Start by powering the machine on and allowing it come to full temperature.

2. Set aside the drip tray and cup warming tray, then remove the water reservoir. Power the machine off and unplug it.
(If your machine has a flow control unit installed, make sure it is in the fully open position.)

3. Place the measuring cup in front of the machine, then lift the brew lever and tilt the machine forward so water begins to drain from the group head. You may need to carefully rock the machine back and forth, eventually dispensing 2-4 fl. oz. of water into the cup.

4. Direct the hot water wand into the pitcher and fully open the hot water valve. The boiler should dispense 24-32 fl. oz. of water.

5. Clean up any excess water.

*NOTE: If your machine fails to power on or fails to heat, you can proceed with steps 1-3 of this guide. You may only be able to get ~2 fl. oz. out of the group head. To drain the boiler, proceed with the following steps.

Tools Needed:
- 17mm crescent wrench
- 5 gallon bucket or large bowl
- Towel(s)

**NOTE: This is not the ideal way to drain this machine; undertake at your own risk. When in doubt, use the buddy system.

1. Remove the panels from the machine.

2. Identify the boiler to hot water delivery tube connection on the bottom of the boiler.

3. Bring the machine to the edge of your counter, with the right side of the machine facing toward you.

4. Place the bucket up against your counter, right under the machine.

5. Use both hands to carefully tilt the machine over the edge of your counter—have a helper spot you, if possible. Then use the 17mm wrench to undo the hot water delivery tube connection on the bottom of the boiler, directing the subsequent stream of water into the bucket.

6. You may have to gently rock the machine to get all the water out.

7. Reattach the hot water delivery tube connection.

8. Clean up any excess water.
