The cause of this could be limescale or salt. If the residue can easily be wiped off with a finger, it is likely too much salt. If the residue is difficult to remove and comes off with vinegar, it is likely limescale.

The purpose of salt in your dishwasher is to soften the water, if you are not refilling your salt then the water will be hard and this will leave residue on your dishes. If you live in a hard water area, you may need to add salt and rinse aid with multi-tabs / "3 in 1" to achieve good dishwashing results. Below is a video advising on how to refill your dishwasher salt.

- Unscrew the cap for the salt container, this will be located at the bottom of the machine cavity on the left-hand side.

- Using the funnel that comes with your dishwasher, pour the salt into the container until full.

- Screw the cap back on and wipe up any excess salt that may have been spilt.

- Run a short cycle with the dishwasher empty to rinse away any leftover salt and avoid corrosion.

Rinse aid is recommended also, this helps with drying and protects glasses from marks. Below is a video advising on how and when to refill your rinse aid.

  • The cause of the problem could be a combination of salt or limescale. If you can wipe off the white coating with a finger, it is probably salt residue. If you cannot wipe the coating off but you can remove it with a small amount of vinegar, it is probably limescale.
