Bosch dishwasher-works, some issues (Nr31 gorleston)

Bosch dishwasher, works but gets stuck sometimes and “check water” light comes on. If i jiggle it around a bit, leaks a bit of water then will work. New one coming Saturday so can go possibly late Saturday or Sunday ? Seems a shame to dump it, may work properly with some attention but it’s beyond me skill and time wise
