Hi
I have a Bosch washer-dryer, no outward signs of problems.
I do a maintenance wash once approx. once a month (powder, hot wash, no clothes/laundry) and sometimes check the trap/filter at the same time. There’s always some water in the base that I have to drain (I’d say more than 500ml, less than a litre) and when the draining pump stops at the end of a cycle, I can hear some water “slosh” back into the machine. Are either/both of these things normal…? Is it hygienic to have water from the drain pipe slop back to the machine?
