Bosch intelligent frost free 44

Gas in fridges and feezers are expensive to refill, if the unit is more than a few years old may be better to replace, if less than 12 months old should contact seller under warrenty.

You can not get advice over the phone or here really

You need knowledgeable folks to be there & see the issue

It may not be getting enough air across the condenser coil to
remove the heat
It may have a refrigerant leak & is boiling off too soon & freezing
the evaporator coil
Or the other suggestions on fan control,switches & such

the fridge might have iced up in the coil due to a defrost problem. one way to check it is to leave the fridge off for a few hours and leave the door open. turn the fridge back on after the few hours and see if the performance is any better. Let me know how it goes

The drain in the freezer behind back lower panel
needs opening. You can see it at the bottom of the back panel
underneath the evaporator coils. (The cold coils)
Run Hot water in the drain until it clears or use a hairdryer.
When the defrost melts the water it goes down the drain
If the drain is clogged with Ice or ? it overflows into the ref.
Run Hot water in the drain until it clears or use a hairdryer.
Also check fan undernearh Ref in the rear
Clean condenser coils underneath

Something to try....on the back wall of the fridge nearer to the top is a little cup like part sticking out. There is water in it but it usually runs down an attached tube inside back wall and ends up under the fridge and gets evaporated. If that tube or the little cup thing is plugged then it will drip in the fridge and collect on the inside bottom of the fridge. So the trick is to clean them out. Check it out ...may solve the problem.

We have the same and I think it is because the freezer door bounces open when we shut the fridge door. Then the freezer compartment ices up, the fan clogs up with ice and cannot blow cold air into the fridge, and the fridge gets warm and the milk goes off.
Solution? We have bought one of those child safety clips (search for fridge safety clip or lock) to hold the freezer door closed.
Simple design error. Expected better from Bosch :-(

My Bosch Frost Free Fridge Freezer did the same thing - Ice forming in the bottom of the freezer area after a few days.

It was caused by a blocked drain pipe - When the freezer does the de-frosting cycle, the melted ice drips into a tray and tehn runs into a dish on top of teh compressor, through a pipe.

If this pipe gets blocked, the de frosted ice overflows from the tray and overflows into the bottom of the freezer and then re-freezes !

To fix, pull the freezer away form the wall, locate the pipe that runs to the dish on top of the compressor and blow through it - This should clear it. Alternatively, from inside the freezer compartment, pull off the cover at the back, but the clips holding it on will probably break off, as mine did ! You can sort of push the cover back on and re-fit the food draws.

Check the ice maker. sometimes they get cracked a will leak water into the freezer compartment. Also check the ice maker fill tube for leaks or someone could have spilled something. Although this is tipical of a clogged drain. What happens is when the fridge go into derfost, it will melt all the frost that is on the evaporator, turning it into water. The water drains down to a trough under the evaporator and down a drain hole in the trough ( this trough is behind the evaporator cover ) Removing the melted frost from the freezer. If that drain is clogged, the water cannot leave the freezer. Then when the fridge starts back up ,it will freez the water that was not drained. After repeated defrosting the water will fill this trough and run off into the bottom of the freezer to be frozzen when the fridge starts to cool again.

The small drain pipe on the back of the fridge gets clogged, hence no drainage when defrosting, hence ice blocks the airflow between the freezer compartment and the fridge compartment.
Remove the rubber stop from the drain pipe and clean (can be found above the motor)
Defrost the fridge for a few days (it takes at least 48 hours). During this time, if you are not brave enough to remove the internal panels of the freezer and continually clean the water, check for water coming out and clean.
If during the defrost there is no water coming out the drain pipe, use about 2m of flexible and strong wire to clean the pipe.
The aim is to unblock the pipe once the ice has melted.

drain is blocked in freezer. take back panel off inside the freezer and you will probably find that the bottom is covered with ice. melt off with a hairdryer and hot water till water flows freely down the drain. needs a bit of patience
