I did all the obvious stuff like empty the water container, cleaned the fluff and also the water container at the bottom. Also got my hand in the back cleaned excess water and gunk. Took the black water pipe off the back disconnected it laid it on the floor and gave it a good suck (yuk) and some water dribbled out. I then put some washing into the dryer with the water hose still disconnected and the water started pumping out and the red water light went off. So I reconnected the black water hose and it works. No red light on and it is drying warm again. Yay.
