H01. During the operation of the dishwasher, special salt can soften the water quality, avoid the formation of scale, and ensure the cleaning effect. The special salt prompt code for Panasonic dishwashers is H01. This code is a prompt message displayed on the display screen of Panasonic dishwashers. This means that the amount of dishwasher salt is insufficient and you need to add more salt. The dishwasher therefore monitors salt usage and reminds the user to add salt if needed via a message on the display. When the H01 code appears on the display of the dishwasher, it means that the special salt has been used. You need to follow the instructions in the instruction manual to open the special salt compartment, pour the salt into the designated location and clean the dishwasher compartment. This ensures sufficient salt and ensures that the dishwasher works properly.
