Hi.
For the past few months, my clothes continue to have a foisty smell after washing. Before this happened, I'd hang my washing on the landing and my whole house would smell of clean washing. Now it smells of sewage (maybe exaggerating).
The washing machine is only about 3 months old.
Things I've tried
Washing at higher temp, moved the waste from underneath the sink trap and located above the trap, put the waste pipe in the right position up and over and facing down (as per pic), used washing machine cleaner, tried biological powder instead of non bio, cleaned the filter and hose at the front near the bottom.
I really am out of ideas and need some help. I have a really strong sense of smell and feel really self conscious about horrible smelling clothes.
