Steam inside a range is unusual, and that is what sets the PRD48WCSGU apart. Its 44.0 oz removable water tank feeds a Full Steam function, so the water supply for the cooking cavity is as important as the gas or electric heat. Mineral scale from hard water is the standard long-term enemy of any steam generator.
On a visit, we check that the tank seats and that the pump moves water, then look for scale on the heater and the lines. A descaling schedule is the best protection. The GN trays that come with the range (some punched, some unpunched, 28 mm and 40 mm deep) should be dry and unblocked so condensate drains.
Two ovens, 3 cu ft and 0.9 cu ft, are supplied at 15,000 W and 50 A, so the terminal connection gets a look too. Thermador lists the model on its site, with no successor named. For a hybrid like this, steam and heat are tested independently.
Common reasons are a tank that is not fully seated, scale on the generator or a blocked line. We check the tank, pump and lines, and descale if needed before replacing any part.
Yes. Minerals build up on the heater and in the lines. Regular descaling and filtered or softened water reduce that. We can check the scale level and recommend the right interval.
Follow the owner's manual. As a general service point, trays with clogged perforations cause poor draining, so keep them clean and clear of residue.
