What E67
actually means.
On the Wolf convection steam oven, E67 (shown with the message F20) points to three possible causes: mineral scale built up in the boiler, a kinked silicone hose, or a temperature-sensing problem. Scale is the one an owner can act on, with a descale cycle.

What to do when E67 shows on the ovenKind of codeSteam and water
The steam oven found its water tank empty, its supply short, or its steam generator slowed by scale. Refilling and seating the tank and running the descaling program come first; a pump, a level sensor or the generator is looked at only after that.
Usually leads toSteam system repair
A steam or combi-steam oven that makes no steam, weak steam or asks for water it already has, traced to scale, the pump, the generator or the tank sensor.
Shows up asOven Not Heating
The oven turns on and the display counts, but the cavity stays cold or only lukewarm after a long preheat.

Before you book,
in this order.
Each step comes from Wolf's own guidance for E67 on its ovens. Follow it to the end: the last card says whether this is a visit.
Turn the breaker off for about 30 seconds and back on, then try the oven again.
If the oven has not been descaled recently, run the descale program with the descaler Wolf recommends and let it finish.
If E67 returns after a full descale, book a visit.
What not to do
E67 is not a sign that the water tank is empty; that has its own prompt. It is about what happens after the water reaches the boiler.
