Indesit EWD71452W washer won't empty water

[KennyT]

Machine is 6 months old. Filter had a very very small amount of fluff but otherwise clear. Impellor turns fine.  Removed sump and no sign of any blockage from drum to pump. Swapped out linear pressure switch but issue has not resolved. Grey waste pipe feels heavy with water for about a metre or so away from the pump. On drain you hear pump sounds suggesting the pump has not failed. Any thoughts as to what the trouble might be? Thanks.

Hello Kenny. I have a very comprehensive troubleshooting guide for a washing machine that won't empty the water here Washing Machine Won’t Drain Water. If none of that helps there is a link at the bottom of the article for further help and advice (Can’t Find a Blockage But Washing Machine Still Not Draining).

You may want to jump straight to the second link, but it might be prudent to check out the first one first just to make sure you have checked everything else.
