If you are noticing white buildup on the bottom of your dishwasher tub, it might be the result of hard water leaving behind limescale deposits.
This scale buildup can temporarily be cleaned by running a cycle using Citric Acid instead of dishwasher detergent.
If you are starting to notice scale buildup or staining from red sauce, put a tablespoon of citric acid in a drinking glass and place it in the center of the top dishwasher rack, then run a normal cycle. If you still see buildup or staining after the cycle is complete, you might need to sprinkle additional citric acid on the bottom of the dishwasher tub around the buildup, and optionally in the detergent dispenser and repeat the normal cycle.
Citric Acid is available at our Martin Water online store, or for pickup at any of our retail locations.
Martin Appliance highly recommends installing a Kinetico whole-house water softener to solve the scale buildup for more than just your dishwasher. Water heaters are negatively affected by scale buildup from hard water as well, and can be very costly to repair and replace. Investing in a softener is a great way to protect your water-using appliances. Contact us for a free, no-obligation water analysis to learn more about how our systems can improve your water quality.
