Descale or DESC error remains on display after descaling a KitchenAid coffee maker.

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

Descale cycle interrupted, Insufficient volume run through machine, Flow meter not registering correctly, Control board not resetting descale flag

Repeat full descale cycle:

Run the manufacturer-recommended descale procedure again, ensuring you do not interrupt power or stop the cycle early.
Use the correct ratio of descaling solution or vinegar to water.

Flush thoroughly:

After descaling, run at least 2–3 full reservoirs of clean water through the machine.

Reset power:

Unplug the unit for 10 minutes, then plug back in and run a normal brew cycle with water only.

If the DESC error remains, the flow meter or control board may not be registering flow correctly and may need replacement.
