Miele Induction Hob Problems 2.0

 Miele Induction Hob Problems 2.0

The Miele hob has gone wrong again. The previous fix was a relatively simple capacitor replacement. This time things are not so straightforward. The initial fault was that the hob tripped the RCB in our fuse box when an attempt was made to turn on either of the front two rings. This happened several times. 

The hob was removed to the workshop to see what could be done. Once wired up there the controls report an FE60 error whenever the hob is turned on.

I managed to find some documents online that said that FE60 was a communication error. After a few hours of going round in circles I decided to buy some replacement PCBs. After swapping all of them into the hob I continued getting the FE60 error. So still no working hob. A cheap-ish hob came up on ebay so I bought that and tried that out. Absolutely amazingly that hob came up with the exact same FE60 error. After ruling out an airborne electrical virus of some sort I finally found out what the problem was when I tried operating the hob with the lights out in the workshop. The lights I was using were interfering with the touch sensors used to control the hob. I suspect the code saw that as a communication error with the push button PCB and reported the FE60 error. 

How do you fix FE60?

Operate the hob with the dark glass cover in place. 

So, hob was replaced in the kitchen with a completely new set of PCBs. As I now have two hobs and about three sets of PCBs I have enough spares to last for a while and can completely swap electronics.

A few days later the RCB trips again. This is with completely different PCBs, so I now think that there's a dodgy piece of equipment somewhere in the house and that caused the leakage current to go up. Induction hobs are known to have high leakage and that pushed the RCB over it's trip limit.

At least I now have spares for the hob for about three decades...
