Recently this dishwasher has left the washed crockery with a rough surface texture. As far as we know, it’s topped up with the correct salt, the right detergent, and Rinse-aid is used.
I have increased the salt setting on the side of the machine to 3 as this is a hard water area, and wound up the Rinse-aid to 4.
I notice the user manual mentions a MAIN FILTER. Does this need cleaning, if so how? Also, the MICRO FILTER looks a bit grotty. Should this also be cleaned, and if yes, what should I use to clean that fine mesh?
