I have an AEG Lavamat 72620 which has developed a fault with the water flow. One of three cogs (orange) on the top of the water ‘dispenser’ seems to have siezed up which prevents the other two turning. Removing the centre cog (white) disengages the top cog(yellow) from the orange one, allowing it to turn and so let water into the machine. Although the machine does work like this I don’t know what the orange cog is supposed to do and am worried that leaving it like this will cause further problems. I can’t seem to get any joy out of AEG so any advice would be greatly appreciated.
