Display shows “ERR” and brewing will not start or stops immediately after pressing Brew.

Safety first: Unplug the coffee maker before removing any covers. Never work on the unit while it is connected to power.

Step-by-step:

• 1. Power reset: Unplug the GE coffee maker from the wall outlet for at least 5 minutes. Press and hold the Brew or Power button for 10–15 seconds while unplugged to discharge residual power. Plug back in and test.
• 2. Check outlet and surge protectors: Plug the coffee maker directly into a known-good wall outlet (avoid power strips or GFCI outlets that may be tripping). Verify the outlet voltage is stable if you have a multimeter.
• 3. Inspect control panel connection (if accessible): Remove the top or rear housing screws (usually under the water reservoir or at the back). Carefully lift the housing to access the control PCB. Check the flat ribbon cable from the keypad/display to the main board; reseat it firmly in its connector.
• 4. Look for moisture or corrosion: Inspect the control board for signs of moisture, coffee residue, or corrosion. If present, lightly clean with isopropyl alcohol (90%+) and a soft brush, allow to dry fully, then reassemble.
• 5. If ERR persists: The main control board is likely defective. Replacement requires matching the exact GE model number and board part number. If you are not comfortable with electronics, contact a qualified appliance technician.
