Beko W/machine fills and drains immediately

[Dazdaz]

Hi. I have a beko WMI 71641 that recently stopped draining. I replaced the pump to fix this. Since then I now have an issue where the water comes in to the machine to start filling the drum but appears to immediately be drained out via the outlet hose. I’ve checked the usual things - water pressure fine, water combining into detergent drawer ok, no pipe kinks, no filter blockages. The machine finally stops after a few mins with a tap with a line though it displayed. I know this implies no water coming in, but as I say I can see plenty of water is coming in…just can’t work out why it goes at ta Ishtar back out! 
 

any suggestions gratefully received.

cheers

As the washing machine wasn't doing this before and has been disturbed the first thing to check is siphoning. Check this article out - especially the section titled, "siphoning water" - fills and drains at same time
