The ‘oh’ error code on an Insignia pressure cooker typically indicates an overheating issue. This could mean that the inner pot has overheated or the unit is not cooling down properly after use. Overheating is a common problem with electric pressure cookers and something many users will experience at some point. Thankfully, there are several troubleshooting steps you can take to resolve the ‘oh’ error code.
What Causes the ‘oh’ Error Code?
There are a few potential causes of the ‘oh’ error on Insignia pressure cookers:
- Insufficient liquid – The inner pot may overheat if there is not enough liquid inside. Pressure cookers need an adequate amount of liquid to create steam and build pressure.
- Food build-up – Leftover debris and food burnt onto the bottom of the inner pot can cause overheating. This buildup acts as an insulator.
- Faulty components – An issue with the heating element, temperature sensors, or control unit can lead to overheating.
- Lid not sealing – If the lid is not sealing properly, the unit cannot pressurize correctly resulting in excessive heat.
The main purpose of the ‘oh’ error is to alert you that the inner pot has become too hot and the cooker needs to cool down.
How to Troubleshoot the ‘oh’ Error
If your Insignia pressure cooker is displaying the ‘oh’ error, try these troubleshooting tips:
Check the Inner Pot
Remove the inner pot and inspect it. Look for any debris, discoloration or warping that could contribute to overheating. Give it a good clean to remove any burnt on food residue. Check that the outer bottom of the pot sits flat and makes full contact with the heating element.
Allow it to Cool Down
Unplug your pressure cooker and leave it to fully cool for at least 30 minutes. This allows the inner pot and internal components to return to a safe temperature. Do not attempt to use it while the ‘oh’ error code is displayed.
Add Liquid
One of the most common reasons for overheating is not enough liquid in the inner pot. For most recipes, you’ll need at least 1 cup of liquid. Add more water or stock before pressure cooking to prevent the ‘oh’ error.
Check the Lid
Make sure the lid is aligning properly and sealing tightly. Look for any obstructions, damage or debris that could impact the seal. Run water around the sealing ring to clean it. Replace the ring if it is cracked or worn.
Contact Customer Support
If you’ve tried the above troubleshooting steps and the ‘oh’ error persists, it’s time to contact Insignia customer support. They can provide further advice and help determine if your pressure cooker needs service or replacement under warranty.
How to Prevent the ‘oh’ Error
You can help prevent overheating and ‘oh’ errors by:
- Checking liquid levels – Always use at least 1 cup liquid.
- Avoiding thick foods – Thick mixtures like risotto can get stuck and scorch.
- Cleaning thoroughly – Remove food residue and give the pot a good scrub after each use.
- Adding liquid first – Bottom layer should be water or broth, not thick sauces.
- Running Natural Release – Allows residual heat to dissipate gradually.
Following the manufacturer’s instructions will also minimize the risk of overheating errors. Don’t exceed maximum fill lines or cook times.
Insignia Pressure Cooker ‘oh’ Error FAQs
Why does my Insignia pressure cooker say oh?
The ‘oh’ error code indicates the inner pot has overheated. This typically occurs due to insufficient liquid, food build-up on the pot, or an issue with the cooker’s components.
How do I fix my Insignia pressure cooker when it says oh?
Troubleshoot an ‘oh’ error by cleaning the pot, adding more liquid, ensuring the lid seals properly, and allowing the cooker to fully cool down. If this doesn’t work, contact Insignia customer service for further help.
What does oh mean on Instant Pot?
An ‘oh’ error on Instant Pot pressure cookers also signals overheating. Follow the same troubleshooting steps of checking liquid, sealing the lid, and contacting support if it persists. The codes can vary slightly by brand.
Why is my pressure cooker flashing oh?
A flashing ‘oh’ code means the pressure cooker has detected dangerously high temperatures. Unplug it immediately and allow a long cool down period before attempting to use it again. Do not override flashing error codes.
Should I unplug my pressure cooker if I get an oh error?
Yes, you should always unplug the pressure cooker if you receive an ‘oh’ overheating error code. This cuts power to allow it to cool down. Do not attempt to start or use the cooker until the error code has disappeared.
Conclusion
The ‘oh’ error code on Insignia pressure cookers typically means the inner pot has become too hot. This is commonly caused by insufficient liquid, food buildup, or lid sealing issues. Try cleaning the pot, adding more liquid, checking the lid seal, and giving the cooker time to cool off. If the ‘oh’ error persists after troubleshooting, contact Insignia customer service for advice or warranty support. With some simple maintenance and preventative care, most overheating errors can be avoided.
