Overview

Model number DGC 7860 XL
Appliance category Microwave

The Miele DGC 7860 XL is a built-in combination steam oven that combines steam cooking with full oven functions in one cavity. Water is held in containers behind the lift-up panel rather than fed from a water line, so the owner refills by hand. The full-height XXL compartment gives room for large dishes, and M Touch with MotionReact runs the touchscreen. A wired roast probe tracks food temperature. The unit needs a 208 to 240 V, 60 Hz, 20-amp supply with a NEMA 6-20 plug. Customers across the Miami, New York, Houston, Los Angeles and San Diego metro areas should include the full model number from the rating label, the error shown and whether the water containers are full.

The XXL full-height compartment and the water-container design set this oven apart from plumbed combination ovens. Because the water is filled by hand, the owner handles the refill and the descaling schedule directly. Automatic descaling is listed among the maintenance functions, which takes some of that work out of routine care. M Touch with MotionReact is the control the owner uses for every program.

Service notes for the DGC 7860 XL

When the oven stops heating or runs off the setting, a technician checks the heating circuit and the temperature sensing, and the wired roast probe is tested separately because a faulty probe can mislead the cook. The owner can note whether the display shows an error code and whether steam is being produced. Water containers that are low or not seated can stop steam cooking, so check the lift-up panel and refill before reporting. Fan, light or display faults are checked once the power supply is confirmed. Run the automatic descaling function when the containers show scale, since scale buildup can interrupt steam production.
