Re: Hoover HND6515 flashing lights beeping fault
Almost certainly a blockage. The first action of any programme is to drain the water, before filling and circulating. The fault is being detected at the end of the initial sequence as a “time-out drain” fault.
If you wish to sort this yourself, bail out as much water as possible and, with the power off, tip the machine back. Look for the grey drain hose coming back across the underside of the machine, where it stops you’ll find the drain pump.
Blockages may not be covered by your warranty, so have a read of the small print before sending for Hoover.
