Reset Miele steam oven - enter hidden programming mode

Question edited for clarity, spelling and 'make model (what it is)'.
Question moved from Miele Coffee Maker to Miele Oven.

Disconnect it from the mains supply for an hour. If that doesn't work, disconnect it overnight. The idea is to reset the control board.

There are instructions here on Fixya on how to enter the programming mode and Reset on a Miele 4082 Steam Oven. Worth a try.

And here is the Manual, just because I can across it.

Press and hold the timer button (the bell picture), and whilst doing that press and hold the power button. Then let go of both at the same time. Then press the timer button 5 more times, but on the fifth time hold for a few seconds. Once in Programming mode play with the options to reset and restart descaling.

Mine did the same thing. Unfortunately, I had to get Miele out to reprogram it. They said it was a "software" glitch and Miele are the only ones with the electronic program to access the software to fix it.

These combi ovens are so prone to problems if you do not have descaling filter system hooked to the COLD water supply (the only water that should be fed to this unit) for your generator inlet. The other water hookup is for your condensate drain (condenses steam leaving cook chamber headed down the drain) and it does not need to be filtered but, also needs to be COLD. These decaling units are quite pricey but, a service call to replace the generator (boiler in laymens terms) will cost 3 times as much & the unit will be down for days waiting on parts. Call Blodgett w/ your model # & talk w/ technical service & ask their recomendation. They can be reached @800-331-5842 & follow the prompts. Depending on your water conditions it is still recomended to descale the unit on a regular basis using a QUALITY descaler (not the junk you buy from Sysco or Dollar general) Cleveland descaler is the BEST.

Put the tablet into the steam generator with about 1ltr of cold water, select the cleaning cycle on your oven. let it go through the cycle.

Hope this helps
