Miele Cva 4066 - Coffee Brewed Into The Pan

its likely to be a problem with contacts in rear of the tray cavity. I would check the following;

1. Remove drip tray and shine a torch into the tray cavity to inspect the receiving contacts that accept the tray contacts. Perhaps theses contacts are shorted in some way.

2. The next step is to open up machine, but you need to be suitably experienced with electrical appliances to perform this step. Disconnect the power at the outlet (or if this is not accessible than at the fuse box). Remove the machine from the cavity and remove the rear panels (making note of which screws go where). Locate the wires that terminate on the contacts on the rear side of tray cavity. Disconnect the wires from these contacts. Replace panels and then reapply power to unit. If this solves your problem .. then there must be a short on the contacts in rear of tray cavity. If this does not solve the problem then trace this wire back to control board and remove wire at the control board. Again replace panels. If this solves problem then there must be a fault in the wire which can be fixed/replaced.. If this does not solve the problem then it would appear to be a problem with control board and best to call Miele.

Please come back if you need more help and also once you solve the problem .. to explain what went wrong.

Thanks
