Have you noticed some white build-up on your dishes after being in the dishwasher? That could be a sign of a couple different things happening. Read on below for how to handle this.
Test Your Water
You'll want to perform a hard water test. Make sure to do this on a hot water faucet. We recommend using a water testing kit or hardness test strips. These can both be found at most hardware stores. For help on testing your water, check out our article on testing water hardness.
The Results?
Where does your water test on the hardness scale?
0-3 gpg or 0-50 ppm
- Your water is soft. You'll want to confirm that the soap dispensers are not blocked in your dishwasher. If the white buildup continues over multiple cycles, the white residue is likely TDS (total dissolved solids) in your water. You'll want to get a sample of your water tested to see what, if any, additional filtration you may need.
Above 3 gpg or 50 ppm
- Your water is testing hard. The white residue is likely hardness minerals settling on your dishes. To resolve this, follow our troubleshooting guide to confirm your softener is working.
