This morning, I found my machine which was on a warm wash had all sorts of strange symbols on the screen. Also, although it was obviously half way through a rinse, it said it only had a minute left. It's also making a grinding noise. It won't drain or spin . Domestic & General won't come out until we've drained the entire WM through the filter, checked for a blockage & left it turned off for 2 hours , to see if the timings reset .is this reasonable ?
