Re: WD860 Stopping Mid-Cycle
sounds like you have an obstruction in the sump-hose/ pump /drain.
the machine gives a generous time to pump out then moves to the next part of the cycle………if the water level is still high enough, it will “assume” it has taken in enough and carry on…..possibly the spin will be inhibited,as it would kill the motor to try and spin under those circumstances…..so yes, it seems logical that you’d get to end of program and have an unlocked machine full of water.
may be worth checking for coins/keys/jewellery/scrunchies/hair bobbles /matchsticks / bits of twig/straw…..jamming the pump or blocking the hoses.
It’s unlikely your guarantee will cover such misuse and you WILL get hammered, for such a callout.
