It sounds like your machine isn't draining the water,
pull the mains plug,its safer for filter and drain pump inspection,
drain the water from the machine by lowering the grey waste pipe coming out of the rear of the machine into a bowl,
once you have drained the water from the drum remove the filter located on the front of the machine,
clean out any debris,
if something has worked its way down from the drum,like a coin or object from a pocket,then it could be lodged in the drain pump.
if its jamming the pump,then it cannot rotate and pump the water out,
with filter removed, restore mains power and put the machine on SPIN ONLY.
Look into the filter housing and see if you can see the pump spinning,
if the pump isn't spinning, turn the machine off, remove the mains plug, and using something like a long handled screwdriver try and turn the impeller on the pump,
if the impeller turns freely then you may have a fault on the pump.
