In Hayward, very low mineral content (<60 ppm tds) or sodium-softened water causes over-sudsing, rubber swelling, and reduced detergent rinsing. This can affect your appliance's wash pump seal: soft water creates excessive suds even with normal detergent amounts, increasing pressure on the wash pump seal and causing leaks Reduce detergent by 30-50% in soft water areas; use detergent specifically formulated for soft water
