I have got a washing machine that will not drain. It is a Hoover VHD 814 I managed to empty the machine by undoing the filter at the botton of the machine..ie at the front at floor level then removed washing and then tried it on a rinse cycle..that worked but it refuses to drain. I presume it must be either..blocked drainage pipe..but it worked yesterday so i doubt its that.or maybe a problem witht the drain pump.Or maybe a problem with what senses the water level? I am up on electronics but this puzzles me as i am not a domestic appliance expert.

check pump itsself

Double check the waste pump on the inbound side, which could be the cause of a wrong feedback to the pressure sensor switch. The filter can be clean, but the collector from the basket to the pump can be obstructed.

Remove all excess water by draining to a bowl. Clear filter and drain pump blade and all will be fine.

this happens with mine too....
Any solution would be very welcome. The machine seems to have a mind of it's own.

the problem is that your machine is not emptying the water fast enough as the machine takes in a good deal more water on the rinse. clean the filter.

I found the basic instructions that came with the washing machine and found that you need a screwdriver to undo a screw to remove the filter cover. I then gradually released the filter cover to empty the water out of the machine in small quantities into a shallow tray. I was then able to remove the filter and clear it of 2 x 20p pieces and a load of gunk. I then removed the 'washable' floormat from the drum as the rubber backing from the mat was crumbling and probably not helping the filter. Filter cleaned and cover screwed back in, mat in the bin, and everything working fine since.

I did try ringing the customer support number and after pressing loads of keys to select appropriate options; confirming my address, postcode, name, date of birth, email address, mothers maiden name, what the kids had for breakfast etc, I was allowed to ask how to get the filter cover off. Apparently this is a technical query and would involve arranging an engineer to call. I declined this very kind service option and opted for a screw driver, common sense and a positive attitude. Worked for me! No blood shed, a tiny bit of sweat whilst trying to get through on phone, and only tears of joy when I fixed it all by myself.

Can you hear the pump running just before the spin cycle, if so then I suspect a blockage in the filter or pump hose, If not and machine is quiet then it could be a faulty water pump or PCB board and you would have to call a technician.

pump blocked try lowing drain hose to see if water will drain freely and then remove kick plate at bottom and carefully undo filter to pump to look for blockage . There will still be water in this part, per pair to get a wet floor ..Also un plug /switch off washing machine before doing any repairs
