Can you help troubleshoot my fridge problems?

[Blu]

It is a fridge freezer, fridge on top.

There is frozen water on the back wall of the fridge, water pooling in the bottom of the fridge, and an icicle running down the door edge of the freezer part.

The top fridge is set to 4' and the freezer to-18'

It is a Bosch Excell frost free. Instructions lost.

What shall I do?

There is a drip tray at the back of the fridge.
It can sometimes happen when it is full.
Also check the hole inside the fridge isn't blocked.
Check the evaporation hole in the freezer too, it might be blocked, most likely cause.
You can also download instructions, I do it all the time.

Turn it off at the plug, take out all the food, wrap it, put in a big box in a cold place, let the fridge and the freezer defrost, leave both doors open until water stops dripping inside either cabinet, or into the dish over the motor, which you will see when you pull the FF away from the wall. Sponge out this dish, avoiding any drips onto electrical parts. Look at the duct openings in the back of the freezer compartment.

Frost-free freezers are prone to getting ice blockages in the ducts behind the back wall inside the freezer cabinet. Being concealed, they take a long time to thaw out.

Unless you have left the door open, it should not need to be done again for a few years. If it happens often, the defrost heaters in the ducts may not be working and it could need an expensive repair.

Clean out the drainage pipe that runs from the fridge gutter and runs to the dish at the back. This dish is usually very dirty (clean it out) and there may be mould or fungus that could block the pipe.

Marvellous - thank you both.

I have had a go at Plan A- clean the little hole in the fridge that water goes down: it was considerably gunked up. I have poked into it with a bamboo skewer covered in kitchen paper and de-gunked the hole.

I can see that no water has been in the drip tray at the back underneath the fridge for a while - so maybe it hasn't been getting though.

If this doesn't work I will employ Plan B - the PigletJohn Full Pull-Through.

But that will take a little preparation: getting the Icey Tek (camping cooler) from loft, freezing some freezer packs, deploying DP etc.

The freezer is full of stuff from the current Waitrose Half Price offer - chickens, mince etc.

Just to thank you both again and to say your advice worked, and everything seemed fine after Plan A.
