The appliance heats and operates, but cooking times are noticeably longer than expected. This is typically caused by the appliance being connected to a single electrical phase instead of the intended two-phase connection, resulting in reduced heating power.
| Possible Cause | How to Fix |
|---|---|
| Appliance is on a single-phase connection instead of two-phase | Have an electrician establish a two-phase (or correct) connection |
