Hi Guys,
Pretty sure this is a common one, but cannot find the appropriate posting to tell me the answer.
I’ve got a Bosch F/F KGU32121GB/02 (R600 refrig) about 30 months old
Every 3 days or so, the bottom of the freezer ices enough that the bottom basket starts to jam. If I remove all the baskets I can see a vertical line of ice coming from the back of the freezer originating from behind a panel on the back wall.
Reading the Bosch manual indicates a possible problem whereby the freezer door may have been open too long and a 12 hour defrost is needed (however the very annoying alarm buzzer would have alerted me I think).
Simple questions:
– Any ideas what the problem is and how to solve it ?
– Can I remove that panel inside at the back and assist in any way to remove the cause or blockage ?Switching subjects completely: Reading through the posts there seems to highlight a higher proportion of problems with Bosch F/F. Does this mean there is a reliability issue particularly with Bosch equipment or is it just that they are more popular and hence you get more posts ?
Anyway many thanks for any help

Re: Bosch F/F icing up regularly
Almost certainly the freezer drain channel has blocked/frozen over. Thus when freezer defrosts insted of water running to top of compressor for evapoation, it flows into the freezer.
Turn appliance off for for 24 hours and allow to defrost completely. Then pull plug out and pull f/f forward. You will see a hose running from bottom of freezer to tray on top of motor. Before removing this put a towel over the fan, then remove and degunk hose.
Problem solved. 😉
P.S. the Bosch F/F fault with the thermistor is on the cheaper KGV range yours is the superior KGU.

Probably the power of Google. Bosch is generally held to be a little better than most, however with the breadth of experience across the trade membership of this site, if you ask the question you get an answer…….. High ratings!

Thanks Guys, will degunk and report back.
Your quick response is much appreciated

I would be very surprised if its a blocked drainage tube. I’m just getting shut of a Bosch KGU3220GB with the same problem. I had to de-ice the freezer every 2/3 mnths for 3 years, otherwise it would reach a point where the fridge temp would start to rise to room temp and the warning alarm beep. The tube was ‘blocked’ – because it had iced over.
The problem happened within 2 months of buying the f/f from John Lewis. The Bosch service engineer claimed the f/f wasn’t faulty, it was because the f/f was sited in a corner of the kitchen and there wasn’t enough air circulating round the back. Although, there was ~2 foot of head space above the f/f. So he said the f/f would always have this problem.
Fast forward a couple of years and I’m refitting the kitchen. The Bosch f/f is stood on its own with metres of freely flowing air space all around it. And surprise, surprise the freezer is still icing up like there’s no tomorrow. (no blocked tubes too). Sadly, the f/f was now out of guarantee. Had a big barny with John Lewis customer care, but they firmly believed I should’ve taken day after day off work to hear the same stories from the Bosch service engineer, rather than trust the first engineer’s diagnosis. Er, right?!
The freezing fault lies with something on the pcb. A new PCB costs around £120, although the fault probably lies with some poorly soldered 10p transistor on the board.
There’s enough people on this and other sites asking why their Bosch KGU’s f/f is icing up for me to think the defrost circuit on the PCB’s are poor quality.
Re: Bosch F/F icing up regularly
I assume you mean the AIR channel was freezing up if the fridge temp was rising.
This is a completely different problem to the original post. Ice in the base of the freezer stopping the bottom drawer coming out can ONLY be caused by defrosted water not running away down DRAIN channel. This problem will not affect the fridge temp.
P.S. The amount of these units that don’t go wrong far outnumber those that do.
Re: Bosch F/F icing up regularly
Hi Guys,
Just thought I’d drop an update on the Bosch F/F.You were right on the diagnosis. I defrosted the f/f, degunked the tube as suggested (and it was nasty inside there) and cleaned everything up.
Restarted and have had no problems for the last 3 weeks.
Thanks again for your help
Cheers
