In the video, the changing of the washing water for the Metos WD-6 dishwasher is shown.
A clean dishwasher is a cornerstone of professional dishwashing. It is recommended to change the washing water of the Metos WD-6 hood-type washer after about 50 washing cycles. Check the washing result and water contamination, and always change water in your washing machine, if necessary. Excess formation of foam harming the washing result quickly reveals to the user that the washing water needs changing.
