Stove guards are fitted in some of our kitchens to help keep you safe while cooking. They're designed to detect danger — like overheating or water leaks — and can even cut the power to the hob if needed. Here's everything you need to know to understand the lights, reset your stove guard, and know when to report it on Planon.
What the lights and sounds mean
Your stove guard uses coloured lights (and sometimes sound) to tell you what's going on.
| Light | Sound | Meaning |
|---|---|---|
| Red (flashing fast) | Yes (high-pitched) | Possible cooker danger |
| Red (flashing slow) | Yes (high-pitched) | Power has been cut for safety |
| Red (one flash) | Yes (low-pitched, three-tone) | Low battery |
| Blue (flash) | Yes (medium-pitched) | Water leakage |
| Blue (solid) | None | Software update in progress |
| Green (solid) | None | Software update mode |
| Green (one flash) | None | Power restored — cooker ready to use |
| Purple (solid) | None | Pairing mode |
| Yellow (solid) | None | Factory reset |
| None | None | Batteries need replacing |
Resetting the stove guard
If your hob and/or oven turns off when you are cooking, it may be because your stove guard has cut the power due to possible cooking danger. On some occasions, there is no danger and you may be able to reset the stove guard to bring power back to your appliances.
To reset your stove guard, simply press the button on the front or side of your stove guard.
If the reset has been successful, power will immediately be restored.
Still having issues?
If your stove guard keeps cutting the power, won't reset, or the lights don't appear to match the guide above, then you will need to report this on Planon.
Don't try to disable or remove the stove guard yourself.
Should it be the evening or weekend, then visit your site reception after reporting the issue on Planon, and tell them you need a temporary hob.
