Hi, sorry for the delay.I cant find the engineer manual for your model unfortunately however assuming your ice cube compartment is water cooled, but Siemens units are a nightmare, are you sure you need to add anti freeze (ie its using water coolant)?My guess is you need to get the gas topped up, which is no easy job as you have to often cut the pipes to do it.However anti freeze is generally added to via the top up valve, this can often be found on the bottom rear of the machine, note its not the inlet for drinking water but a smaller push fit valve, you attached a flex hose filled with anti freeze to the top up valve, then the other end to mains water to 'pressurize the system'. It is not easy job, and can cause more harm than good, I would suggest you get an engineer out.Saying that have you checked the rear has adequate ventilation, the ice make door has been properly closed and the seals around the unit are all good?
Hi, sorry it appears two questions got merged, I have now managed to isolate your question.
Right this sounds like a door seal issue as the fridge is getting cold clearly, but moisture is forming which in most cases is due to a poor door seal
Sorry that should have been check the freezer door seal
The other thing to check is the clearance at the back of the unit, as it may be the motor is overheating and so temperature is fluctuating.
Open the door run your finger along it to see if there are any rips in it, then shut the door and check the seal is touching the freezer. you may need to open the fridgedoor to check all the way round.It could simply just be your door needs adjusting to make the seal sits tighter, I
Have you checked what the freezer temperature is correct in the other sections, it may also be worth checking the clearance is still the same as it was previously as if the motor start overheating that can cause performance issues.But it does sound like a door seal issue on the face of it
Hi Jon,Sorry about the delay in getting back to you.If the door seal is working correctly its likly to be one of three things. The coolant gas has leaked out and needs recharged, the compressor has gone faulty or the thermister which measures the tempature is giving an incorrect reading
My view is that its the thermister, which is by chance the chepest part to replace.This is normally located in the unit which controls the temp settings, turn the temp up to its highest setting, give it 5 minutes then go back and turn it down to the lowest setting, wait a minute and see if the compressor starts. If it does repeat the step again but this time start highest setting and go down to middle way, and see if it starts.What we want to do is prove is the thermistor is actually telling the compressor to start at the right time, if its only comming on when at the lowest setting its time to replace the themermistor.Do you have a multi meter, as this would be needed to fault find issues with the compressor.
Yes, this is the thermistor
I dont have a picture of it, so if you want you can send me a picture and I can confirm?
