What does Newco error code E-A mean?
The brewer watches for signs of leaking water, and the manual names this alert E-A (Leak Detected). The wording is careful: the water system may have a leak. That means the brewer has sensed something consistent with water where it should not be, and it stops to protect the counter and the electronics. The manual says power must be cycled to clear it. The cause it lists is that the water system may have a leak. The only action is to check all plumbing system parts for a possible leak and to look for water on the counter or the surrounding area. It does not name the sensor or where water might be found, so a technician works that out from the brewer. For you, the first job is to look for water, because a real leak needs to be dealt with before power is cycled again.

Possible causes
Listed in Newco's documentation
- Water system may have a leak
Other likely causes — what usually sits behind error code E-A on this control. A technician confirms which one it is before any part is replaced.
- Loose inlet hose or fitting at the brewer or the shutoff
- Cracked or worn internal water tube
- Tank or valve fitting that is seeping
- Spilled water or condensate that triggered the detection
Safe checks before calling for service
- Switch the brewer off and unplug it before touching anything wet.
- Look for water on the counter, shelf or floor, and check the inlet hose and its connections.
- Dry up any water you find and wipe the base and back.
- Plug the brewer in and switch on again to clear E-A, as the manual requires. If it returns or water is still present, shut off the water supply and call for service.
- Tell the technician where you found water and how much.
How a technician diagnoses error code E-A
- Read the display and confirm E-A.
- Inspect every plumbing connection from the supply to the tank, valve and dispenser.
- Check the brewer's leak detection and the area it covers.
- Pressure-test the water lines if no visible leak is found.
- Repair the leaking fitting or part and confirm that E-A does not return.
- Water near live line-voltage wiring is a shock hazard.
- Pressure testing and fitting repairs need tools and proper knowledge of the water system.
- A leak inside the cabinet can only be found with the covers off.
