I forgot to add another crusial point, even if the hot water tap is on, and you have a source of hot water, but the machine may not take that in due to the hot solinoid valve not functioning thus preventing the entery of hot water into the machine, My mother once turned bot Hot and Cold water taps off and forgot to turn them back on again, and next day when she put the washing on, the machine was trying to fill the water but no water would enter as it had been turned off, so what happened next was the solinoid valves became overheated and coils burnt up, and we called in an expert, who couldn't fine the fault and said we need to throw the machine out and get a new one in, well I told my mum don't throw it out yet, let me have a quick look, so it didn't take me 5 minutes to figure out why the machine didn't start, because unless the water is filled to the correct level, a pressure diapharam switch senses how much water has gone into the machine and then signals the electronic board to start. Needless to say that machine worked for another 10 years.
