Miele Induction Hob Problem
We've had a Miele KM5731 for nine years or so, it took a while for me to fit it after we bought it, so it's probably been installed for more like 8 years. Anyway, a few days ago it started to give an error code of FE32.This is the hob, it has four induction coils and some touch buttons.
The error code appears in the power level displays:
Once the error code appears the hob is unusable. The instruction manual isn't much help, it says turn it off and on again. Well, that might work, but it's got progressively harder to conjure away over the past few days. A search on the internet resulted in many useless sites and one very useful Dutch site. From that site it transpires that there are a couple of capacitors on the power PCB that can pop and lead to this error code. I took the hob apart and had a look and indeed there were two capacitors with bulging tops.
They are both 470uF 25V electrolytics, this one has split and opened:
This one has just expanded on top:
I ordered some new high quality capacitors to replace these two and also some to replace the other electrolytics on the PCB. These arrived today and I have replaced the capacitors. So far no sign of FE32, but we'll have to see over the long term whether it's fixed or not.
Interestingly the decent quality (Panasonic) capacitors I ordered were identical to the ones fitted, except for the date code, apart from the two that had popped. So it looks like maybe there was a supplier issue with those two.
