Turn the breaker off for about 30 seconds and back on, then try the oven again. If it comes back, it needs a visit. ### My Wolf steam oven shows F20. Is that the same as E67? Wolf's page pairs them: F20 is the message shown with error E67. Either way the first owner step is a breaker reset, followed by a descale if one is overdue. ### I descaled my Wolf steam oven and E67 is still there. What now? Scale is only one of the three causes Wolf lists; a kinked hose or a temperature-sensing problem are the others, and neither is something to open the oven for. Book a visit and mention the date of the last descale. --- **[Read on the site: Wolf convection steam oven showing E67 | OvenRepair.center](https://ovenrepair.center/error-codes/wolf-e67/)** **[Book a visit with OvenRepair.center](https://ovenrepair.center/schedule/)**
