The clothing is actually being left as if bleached in patches! I guess I should just use calgon with no clothes and see if that makes a difference going forward.
2001 Bosch 245 Washing Machine leaving mottled bleach type marks on coloured dark clothes all of a sudden. Presently use calgon alongside Persil biological washing powder at 30º. Anybody any ideas as to what could be causing it and what remedy, if any, there is? Thanks in advance.
