Could be anything best to get someone who knows what he doing these appliances can be tricky with all the different components in them so we found out when ours kept doing the same thing we had an engineer from www.agsrefrigeration.co.uk came out to look at ours and found that the fault was something to to with the ice functioning mechanisim which he replaced all good now
