The drain hole is blocked & probably iced up.
Remove the drawers
Remove the inside back panel (4 'torx' screws - need a torx driver) then see the drainhole low onright hand side.
Defrost it with hairdryer , until water flows freely.
Check visually there's nothing blocking the hole entrance, which narrows as it cnters a rubber tube, about an inch down.
If it freezes up and blocks again repeatedly, it may be blocked or gunGED up where tube enters drip tray, then you'll need to remove the tray to clean it. That's can be tricky.
Go round the back, switch off & DISCONNECT entirely from the mains power supply.
If you are confident to continue.
Copper pipes seem to make removing the tray, held by 2 obvious screws, impossible.
However, the trick is to ease the compressor out just enough to let the tray be angled out, with some difficulty.
You'll see the compressor sits on a trolley containing the wheels, which is only about 6 inch approx, deep.
2 screws, one on each side hold this metal trolley in place.
Remove them, then very gently ease the trolley backwards , out of the body of the freezer, but by NO MORE than an inch or Two.
Doing this will put stress on the copper pipe that runs across the back, so watch it.
That should allow tray to be removed for cleaning, after you reach in and detach the rubber hose where it attaches at the left side of the tray.
Clean the trayTHOROUGHLY, particularly in and around the chamber that the rubber hose fits into .
Check for free flow through the tube .
Try feed & pull something through the tube to clear it.
A flexible tube or coated wire may be handy but be careful not to damage the sides of the tube, which isn't straight.
When it's clear & clean refit the tray and reattach the hose before securing the tray with it's screws, which are also used for levelling.
Run some water in and watch how it flows around the tray, setting the level (with screws) to avoid overflowing the left sides.
A small hollow tube may be handy for siphoning excess water out of the tray chambers, before restoring the compressor on it's troley & resecuring .
