Hotpoint fridge freezer ff200tx error fault code a1

[sangha18]

Hi all am new to this site and would appreciate any help with my HOTPOINT FRIDGE FREEZER FF200TX ERROR FAULT CODE A1,

Every few hours the displays has error code A1 displayed and beeping signal, If I switch it off and on then fine for another 2 hours or so, the freezer and fridge seem to be working fine, couple of days ago removed the panels in freezer and defrosted the ice build up, over the last week have checked the compressor and evaporator on the back and there was no water on top of it, which usually had has some traces of water in the past. Not sure if heater is working to defrost, checked all connectons all seem fine, Thanks for any advice in advance.
