A while ago I had a problem whch turned out to be a blocked pump – not long after resolving this problem the machine, although working fine, started emitting a single beep at unequal intervals during the wash cycle. As I say m/c seems to be working fine apart from this annoying beep. I’m assuming an intermittent fault causes the single beep as it isn’t at regular intervals. No leds flash to indicate a particular fault — any ideas / suggestions appreciated.
