My Indesit WD12 has suddenly stopped warm washing everything. It doesn't appear to be taking hot water in, neither is it heating water which is not yet at temperature. So far I've uncoupled the warm water feed pipe and removed the red plastic filter, which is clean. I'm not touching anything else without expert advice. I know nothing about washing machines except that what comes out of them is generally expected to be cleaner than what went in. Otherwise its working fine. If this isn't the first such submission then apologies for repetition repetition.
