Solved my own problem.
Take out the bottom drawer by pressing the catches on the side at the front. Lay it on its side so you can reach inside. Wipe the bottom dry. Locate the flood sensor which is a little raised inlet about 2/3rd from front and 2/3rd from left side. Blow this with a hairdryer set on warm for 10 minutes. Reassemble.
Worked for me. good luck
