The fridge drain hole allows water from condensation and defrost cycles to exit to the drip tray. When this hole becomes blocked, water pools inside the fridge or freezer, causing leaks, odours, and frost buildup.
Signs of a blocked drain hole
- Puddles on shelves or at the bottom of the fridge
- Foul odours from stagnant water
- Ice forming in the freezer due to poor drainage
- Excess condensation on walls
Common causes
Food debris
Crumbs, vegetable peels, or sticky liquids can clog the drain.
Ice blockage
In frost-free fridges, the drain hole can freeze over, stopping water from exiting.
Poor maintenance
Neglecting to clean the drip tray or drain area increases the risk of blockage.
Repair options and costs
- Unblocking the drain manually: £20–£50
- Professional service for frozen or hidden blockages: £50–£120
