Error codeF7E1
ApplianceWall Oven
When F7E1 appears, the manual says the Water Boiler Temperature Sensor, or the wiring that goes with it, may have a problem. It is listed for wall ovens.
Reset routine
Switch the oven’s circuit breaker off and keep it off for a minute.
Switch the breaker on to restore power.
For the next minute, watch the oven to confirm the code does not return.
Do a final check of oven operation.
If F7E1 comes back after the reset, the next step is a technician visit.
F7E4: the water conductivity sensor and its wiring.
