If the indicator of Out of dishwasher salt lights up on the Xiaomi Tabletop Dishwasher, please check if the dishwasher salt is insufficient or if the dishwasher salt sensor malfunctions.
To resolve this issue, please refer to the following steps:
1. Ensure that you have added the dishwasher salt to the softener;
2. If you added salt but did not fill it with water to dissolve the salt, the softener float will not rise;
3. If the softener float is stuck and cannot rise, gently tap the float to lift it, or replace the softener component;
4. If the float rises but there is no signal from the float sensor, check if there is a 5V voltage output at the float sensor signal wire;
5. If there is no 5V voltage output, check if the signal wire has continuity. If not, replace the signal wire;
6. If the softener signal wire has continuity but no voltage output is detected, replace the main board.
