The display shows “E3” and the single-serve side of a FlexBrew does not pump water.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Airlock in the single-serve water line, Clogged upper or lower needle, Failed single-serve pump, Blocked internal check valve

Safety first: Turn off and unplug the coffee maker before cleaning the needles.

Clear Needles and Airlock:

Remove the single-serve pod holder.
Use a straightened paper clip to gently clear the upper piercing needle and the lower exit needle of coffee grounds.
Fill the reservoir and run a brew cycle with no pod to flush air and debris.

Prime the Pump:

On some models, you can run 2–3 consecutive water-only cycles to help prime the pump.

If E3 persists and no water moves, the pump or internal valve may be defective and require replacement.
