So our Dyson started playing up. It would cut out randonly. The Boost button would flash blue for about 10 secs then it would stop.
I removed the battery on pressing the button on the battery direct it turns blue then switches to green and off.
I stripped and cleaned the hoover and no blockages. I bought a new battery but that turns blue on plugging in charger then few seconds later switches off. When i press the button directly on this battery I get nothing.
I bought a new charger and tried that with old battery, it goes blue then at some point switches off to indicate full charge but then still when in boost mode starts flashing blue then off. With boost switched off I seem to get good run time.
I tried a battery from a different machine and same thing happens with boost selected.
Any ideas peeps?
