Samsung Fridge Freezer pooling water in freezer base question

[NeilDiamondsBlowDry]

Hi I have an old (probably 15 years ) frost free Samsung fridge freezer it’s been totallly trouble fee until now but last night i took out the bottom drawer and it was frozen in place about 1cm of ice built up clear like ice cube looking. Got all the ice out but I see now it has started again just a very thin sheet for now. There is plenty of air coming out of the vents. Has anyone else had this and is it time for a new one ? Edited to add it is very full at present . Thanks in advance

I had this. I googled the make & model of the fridge to find the instruction manual. It said I needed to unblock the drain hole using the drain-hole unblocking tool. I didn't have that, so I got one from either a spares shop or Amazon - can't remember which. It looked like this and did the trick: https://www.espares.co.uk/product/es594359

@ledclok thank you so much. googling does mention the drain hole as well. Is that the drain hole in the fridge part ……many thanks for your reply, (I have bought from e spares before they’re really good )

Yes, it was in the fridge. It was blocked, so the condensation couldn't drain and was pooling in the bottom.

Use the refill out of a biro to clear the drain
