Learn why your V60 Drip Scale isn't taring correctly and how to fix it. Step-by-step diagnosis for accurate pour over brewing.
Quick answer
A coffee scale that won't tare usually has a dirty sensor surface, low battery, or is overloaded. Clean the platform, replace batteries, and ensure your container is under 2,000 grams.
Why tare errors happen
The tare button resets the scale to zero so you can weigh only the coffee. When it fails, the scale is likely confused by a dirty sensor, weak battery, or weight exceeding its capacity. The V60 Drip Scale can handle up to 2,000 grams, so a heavy server or carafe might be the culprit.
Another common cause is static electricity or moisture on the platform, which can interfere with the load cell. Wiping the surface with a dry cloth often restores normal function.
Diagnosis and fix
- Symptom: The scale shows an error code or won't return to zero when you press tare. If the display flashes 'EEEE' or stays stuck, move to the next step.
- Likely cause: Dirty sensor contacts, low battery, or an overloaded platform. The V60 Drip Scale's load cell is sensitive to debris and voltage drops. Check the battery compartment first—weak batteries cause erratic readings.
- Corrective action: Remove the container, clean the scale surface with a dry cloth, replace batteries with fresh ones, and power cycle the scale. Then place an empty container and press tare again. If the scale still won't tare, the load cell may need professional calibration.
- When to stop or choose another option: If cleaning and new batteries don't fix the issue, the scale may have a hardware fault. Contact Hario support or consider replacing the unit. Do not attempt to open the scale—it voids the warranty and risks damaging the sensor.
Product facts
- V60 Drip Scale Black: The V60 Drip Scale weighs in 1 gram and 1/10th gram increments, with a capacity of up to 2,000 grams. If your container plus coffee exceeds 2,000 grams, the scale may not tare correctly. Use a lighter vessel or weigh in stages.

V60 Drip Scale Black - V60 Drip Scale White: The V60 Drip Scale White has the same 2,000-gram capacity and 0.1-gram precision as the black version. Color doesn't affect performance, so choose based on your kitchen aesthetic. Both models require the same troubleshooting steps.
