When your digital scale keeps changing weight, there are a few issues that can cause this to happen. After you figure out what may be causing this issue, you can fix the problem so your scale can work correctly.

Residue and grime build-up

Over time, residue and grime can build up on your scale. This can happen from food and grease in your kitchen that comes in contact with your scale when baking.

This grime and residue can build up, leaving to your scale give inaccurate readings. Be sure to regularly clean your scale to prevent build-up from grease and food from happening.

Water damage

Kitchen scales aren’t waterproof, so if water and moisture get in, it can cause damage. In some cases, the scale may not work at all, whereas other times it may just cause inaccuracies while weighing your ingredients. If you ever spill any liquid on your scale, be sure to clean it up right away and make sure it is properly dried.

It isn’t properly calibrated

Sometimes, scales can become un-calibrated over time, causing them to not work properly. You may need to regularly calibrate your scale so it can run properly.


Kitchen scales do have weight limits. If you add too much weight to your scale, it may cause it to overload and then lead to inaccuracies when weighing. Be sure to read the weight limit of your scale so you know what the limit is and try to avoid weighing things that are too heavy.
