Question about Bosch Classixx KGV28323 Bottom Freezer Refrigerator

Bosch Classixx fridge / freezer

I have had to withdraw 4 of the 6 Bosch fridge / freezers from our sudent accomodation blocks. All with the same problem, the freezers are fine but occasionally the fridge becomes warm. When I reset using the on/off button I can hear the recirculation fan but when I inspect a faulty one it's never running. All f/freezers were supplied about 18 months ago in one batch.

    Interestinly enought I seem to have the same problem, all was running fine until about a month ago and then warm fridge (10 degrees)

    Thought of replacing the thermostat but I think the idea of switching it off with the door open for a few hours is a good one (hopefully the freezer section will survive)

    will try that tonight before going out for beers and hopefully it won't cause a problem if I am late back from the pub

    The Fridge section is real problem. The temprerature seems to range from 5 - 10 degress and cannot set it to anything less than 4 and it quickly rises again. Another problem is creating frost inside regardless of the temperatures spoiling the green vegetables. Anyone with any answers to this on

    I have a Bosch Classixx and the same problem with the fridge going warm. The Bosch people told me to turn it off for 48hrs and defrost. OK?? It is a frost free and there is no frost. So after throwing out food from my fridge now I have to loose all the food in my freezer too. ... Being patient and ever hopeful I dutifully do as told -- well, you guessed folks -- it did not work. So now the engineers are coming out on friday next so will post an update. Good luck to you all and To All A Happy New Year.

Hi - experienced this myself and spent ages trying to get to the bottom of it - only found one post but it worked and was absolutely clear on the cause nb: i'm not an "expert" !

My understanding of how the Bosch f/f works is that the freezer compartment generates the cold air for the fridge which is regulared at the fridge end . At the back of my fridge there are two "vents" which feed up this cold air up from the freezer into the fridge.

Problem happened to me because I left the freezer door slightly ajar which generated a massive amount of frost (sucking in the moist air from the house I guess then freezing it) and subsequent ice froze up the cooling ducts between the freezer and the fridge. Therefore, no matter how much I turned up the fridge thermo it never got cool. Only solution was to dump my frozen at a mates house and defrost the the FREEZER for a good 24 hrs +.

Worked tho' - fridge was completely back to normal.

PS: I understand this issue may also happen if you put too much unfrozen food into the freezer at one go and in working overtime to get it frozen causing a massive frost up again.

I know there was a faulty batch of these some time ago... freezer ok but fridge staying warm. The outcome was that the defrost pipe at the back was blocked (manufacturing issue where it was squashed or something along those lines stopping the water from escaping on defrosting) The ice wouldn't defrost stopping the fan from spinning around for the fridge to get cool. Easy check is inside the freezer section you can see the metal elements at the top through the plastic cover.... These should never be frozen over to any degree as they defrost and freeze constantly. Frankly my experience of fridge freezers is totally appalling as none of the common major manufacturers can actually build one of these things to any standard. I'm on my fourth frost free fridge freezer... first 3 were replaced within 7 months of ownership due to manufacturing failure ! 2 x Hotpoints and 2 x Bosch Classixx. Frankly they all appear to be a pile of rubbish !!!! latest Bosch is now on the fritz after 2 years.... which isn't very long really is it ! Again i think its this blocked pipe issue which i believe to be at fault.

I tried switching ot off for 2 hours last night, but didn't defrost the freezer section at the same time.

Result is hat today the fridge is now warmer then yesterday, and no water cam out of the back during the process

Do I need to also defrost the freezer section at the same time ?

I took off the inner panels that are the 'multiflow' for the cold air, and no ice behind them

Would love to know if there is another potential cause

Many thanks

Ours has been the same - seems that although it is 'frost free' the fridge section can block with ice, inside the panels (so you cannot see any problem).

We have found that switching the unit off and letting it thaw out (catching water at the bottom rear) works but the problem always returns in time.

Takes several hours to thaw.

Once the fridge is shut OFF for few hours to defrost and then switched ON , if the fridge works with cooling , then the fault is with the AUTO DEFROST TIMER or the circuit -maybe the heater, break in the lines to the timer, heater, the fan.
The build up frost will block the flow of cool air to the fridge from the freezer evaporator.
So remove and check.

Bosch Fridge, Freezer OK but Fridge won't cool

Well nobody came up with any other options so I guess it's just defrost a "nonfrosting" fridge every three months or so, just like the old days.
No progress here then in spite of advances? in technology.

Bosch KGU31124 Freezer Not Working

I have the same freezer and get the same problems. Ice forms on the refrigeration fins beind the plastic shroud at the rear and completely blocks the airflow. The fan that moves cool air around does not work then and freezer temp goes up. Ice will often push the shroud forwards so that the door does not close properly. Warm moist air get in and just increases the ice problem.

I take the shroud and fan housing off the rear (4 screws and a wire to the fan) and defrost thoroughly using a hair dryer. You can then see when all the ice has gone..

We have the Bosch kgn34x60 fridge freezer and the fridge wont stay cold. The dial is turned to 5. Any ideas on what might be the problem????? had it less than ayear and the freezer is fine

I have this model and am having the same problem. Bosch don't want to know as it is out of warranty.
This means that a perfectly good freezer has to be thrown away because the fridge won't work properly.
Don't buy Bosch.
