After a hot dishwasher rinse, the bottom collection sump cools rapidly and its walls instantly
condense water. The photoelectric level switch cannot tell "condensation" from "real water"
and sends a false full signal to the mainboard — the inlet pump stops, the drain pump runs
dry. Long-term detergent immersion also clouds the photoelectric lens.
Shenzhen Xingkechuang Technology Co., Ltd.'s non-contact capacitive level sensor sticks
to the outside of the PP sump. The capacitive principle determines the true liquid level; the
ΔC from condensation film is filtered out. The probe is fully sealed, detergent-corrosion
resistant, and requires no modification to the dishwasher water circuit. For kitchen-appliance
factories, this single change can cut the "false full water" complaint category by roughly 70%.
