Warning light - Bosch Classixx KGV28323 Bottom Freezer Refrigerator

Red light on for High Freezer Temperature Warning
or freezer not cooling, but fridge is and a lot of noise from compressor.
Also, fridge drain hole blocked, water in bottom of fridge.

This is a common fault in Hotpoint Fridge Freezers and can also happen if the door has been left open or has been a power cut.

1. Turn off fridge freezer, or at least turn down the freezer temp to minimum, though not ideal.
2. Open freezer door and remove all drawers.
3. Remove the back panel on the inside of the freezer. This is held in place with 4 screws, which might be 6mm hex head or star allen head. Pull the panel out.
4. Behind where the panel was, there is a cooling element for cooling, pipes, and below this a temperature sensor. If the fridge freezer is not switched off, then fold together a few layers of tinfoil and wrap around the sensor.
5. Use a hairdryer to slowly melt the ice. Melt it around areas where it appears to be hanging on, such as the corners of the cooling element or bolts, as well as any thin sections below the main block of ice around the cooling element, which will be supporting the main block. Use a plastic ice scraper to remove ice but not near pipes or sensor.
Warning: Be careful using electrics around water & melting ice & drips.
6. Below the cooling element, there is a drip channel & drain hole. If this hole is full of ice, pour a small amound of warm water down, leave for 10 seconds and pour a bit more until clear.
In the fridge, clear the drain hole in the same way.
Warning: Do not pour a lot of water down, as this water drains onto a tray above the hot compressor at the rear of the fridge freezer to be evaporated by the heat of the compressor and the tray will only hold a small amount.
7. When all ice is removed, dry all moisture. Put the shelves back. Close door. Turn on fridge freezer. Turn up the freezer temperature to your normal setting. Turn on fast freeze if available. After 1 hour, check with a thermometer. It should be cold enough after 1 or 2 hours.
