Had the same fault symptoms this week. Water in base due to motor/ circ pump noisy for a while, seal gone and leaking badly. Motor was begining to cook itself and prog stopped at 30 mins. Its a possibility 😉 .
First thing to check is the water inlet matrix, pressure switch unit and sump transfer pipe? If they’re gunged up (and they usually are) then water spills over the top and onto the base. 😯
