Hi. We noticed pur cupboard next to our fridge was really damp. We have also been having a lot of water at the back of the fridge. Tonight I habe taken of the back panel.and there is some water in the drip tray but it's not overflowing. I have cleaned pipe that leads to this so there are no blockages. What could be causing the damp? There is also a pipe that leads to the heater panel which looms green (corroded). Could this be an issue? I've left the fridge out and have put a bowl in the drip tray to see if any water there in the morning. Any ideas?
