What to do if my John Lewis JLBIOSS650 does not heat up?
- DDennis GreenAug 9, 2025
If your John Lewis Oven isn't heating up, there could be several reasons: * The oven might be turned off, so ensure it is switched on. * The clock may not be set; in this case, set the clock. * The settings might be incorrect, so verify they are properly configured. * The automatic switch-off function could be active; check the "Automatic switch-off" function. * The Child Lock might be enabled; refer to "Using the Child Lock" to disable it. * The door may not be fully closed; ensure it is completely shut. * The fuse may be blown. Confirm the fuse is the issue, and if it repeatedly blows, contact a qualified electrician.
