The fault almost certainly is caused by a blocked pump hose to the condensor reservoir. Take the LH side panel off to access the small black hose and clear the blockage. (Usually caused by the customer not cleaning the condensor matrix and fluff filter regularly)
Flashing cupboard dry light indicates overheat condition, Tech info suggests “checking air route and pollen filter” ?? personally I would carefully check condensor matrix, washing out in all directions with garden hose
