Re: WDL520P
Hi
I had a WML540 the other week with similar symptoms.
Fill, Pause, fill, motor starts to agitate will filling, lights all start to flash and pump kicks in to drain.
When the lights/pump kicked in the water level was just over the edge of door seal which is too high.
In my case turned out to be the pressure switch causing overfilling.
May be worth checking pressure system is not blocked or there is a problem with the switch.
