SOURCE: Hidden Ice build-up inside plastic bottom cover of freezer
Generally, icing is the result of too much water vapor inside the unit, blockage of the circulation channels and too much packing in of the box. The water vapor is generally caused by: uncapped items in the fridge, opening the door too often, humid conditions, bad door seals. There is of course, there is a possibility that the defrost cycle on the unit is not working. About once a day, depending on the brand, you should notice that the fans and compressor don't run and you should hear a bit of creaking, sloshing or other strange noises as the ice melts. If this is not happening, your defrost timer or the coil it heats could be bad.

Check the ice maker. sometimes they get cracked a will leak water into the freezer compartment. Also check the ice maker fill tube for leaks or someone could have spilled something. Although this is tipical of a clogged drain. What happens is when the fridge go into derfost, it will melt all the frost that is on the evaporator, turning it into water. The water drains down to a trough under the evaporator and down a drain hole in the trough ( this trough is behind the evaporator cover ) Removing the melted frost from the freezer. If that drain is clogged, the water cannot leave the freezer. Then when the fridge starts back up ,it will freez the water that was not drained. After repeated defrosting the water will fill this trough and run off into the bottom of the freezer to be frozzen when the fridge starts to cool again.

My fridge (E440T but I believe the E522B is similar) had a broken fan wire and i had to pull off the rear panel and re-solder a wire. I created a document for others to follow that shows the rear panel removal if interested at http://www.accentis.com.au/downloads/misc/How I fixed my Fisher and Paykel Fridge Active Smart Fridge.pdf
Thanks to all postings on this site - it really helped a lot.

There is normally a small filiament of metal which is attached to the defrost element and conducts heat down the drainpipe preventing ice build up. You can pour some boiling water onto this area and even wriggle a piece of plastic tubing down the drain pipe to dislodge any blockage. For future prevention, you can attach a piece of copper wire around the defrost element (in the absence of the original filiament) and extend it down the drainpiple
