Tools Needed:
- 13mm crescent wrench
- Multi-grip pliers (aka Channellocks)
- Large measuring cup OR pitcher and tared scale.
- Recommended: 8mm ID or 1/4"-3/8" ID silicone tubing
1. Start by removing the top panel from the machine.
2. Identify the braided line from the pump to the boiler inlet connection.
3. Disconnect the braided line at the boiler using the 13mm wrench.
You may need to use a pair of multi-grip pliers to hold the braided line while you turn the hex fitting.
4. Pull the braided line over the side of the machine and direct it into a large measuring cup or pitcher.
It may be helpful to add a length of silicone tubing to the end of the braided line to prevent spilling water.
5. Re-install the reservoir and fill it with water. Then power the machine on and flip the brew switch to activate the brew pump*. Observe the output; water should flow freely. If the flow from the braided line is weak or non-existent, you'll have to continue troubleshooting further up the flow path.
A properly working vibratory pump should push at least 200g (~6-8 fl oz) of water in 30 seconds.
*NOTE: Never run a vibratory pump for longer than 1 minute at a time. Doing so could burn the pump out. Allow the pump to rest for 1 minute in between every 1 minute period of activity to prevent overworking the pump.
