Re: Neff S5443 not heating up fully
There are two standard problems (widely posted through this forum) which cause poor/no heat issues.
Firstly is a dry joint on the computer board in the top of the door. This can often be resolved with a soldering iron and wire.
Secondly, the machine may be underfilling due to an accumulation of food deposits in the transfer pipe across the front lower part of the machine and the fill/pressure chamber on the left hand side.
Heaters do occasionally fail, but this would give you no heat at all.
