Where abouts is the water is it in the white plastic sump?
Is it still make the buzzing noise?
Ok this sounds like the machine has leaked in the base and brought the anti flood on thats why its making that noise.
pull dishwasher out and then tipp it back 45deg to let the water drain out then try it again and see what happens.
As to the water in the sump they always leaves water in there so thats ok.
If you need anymore info just get back to me.
Ok if you remove the cover from the pump impeller again make sure it turns ok
it should ping round it its stiff then its either block or the pump is at fault.
so if you remove pump from underneath it will just twist off you can check it then retry if still doing it then the pump will be at fault and would need to be replaced.
if you need anymore info just get back to me.
Ok have you checked the drain hose were it drains to
if under the sink remove the spiogt and make sure its not blocked.
then put hose in a bucket and reset the machine and see what the water flow is like
if it just trickles out then there is a blockage if no water comes out atall the changes are the pump will be at fault.
let me know what you find.
Ok this normally happens when there is a leak in the base
pull it out and remove both side panels
Do you see any water in the base
look on the left side there is a red bar which goes down to the botton lift this up and down you should hear the swich clicking make sure the rod is down then retry it
let me know how it goes.
Glad its sorted for you.
and thanks for payment.
