The following are possible reasons why an electric pressure cooker might fry its contents:
Insufficient pressure-bearing capacity of the pot:
If the pressure cooker frys its contents under normal operating pressure, it's likely due to a defect in the pot's pressure-bearing capacity, a product quality issue. In this case, contact the dealer or file a complaint with the consumer association.
Pressure valve malfunction:
A stuck or contaminated pressure valve can prevent proper pressure release, leading to overpressure and frying. Regularly check and clean the pressure valve to ensure it functions smoothly.
A blocked vent in the pressure valve can also prevent pressure release, causing overpressure and frying. Regularly check and clean the vent to ensure it's clear.
Safety valve failure:
If the safety valve fails to release pressure under overpressure, this is also a product quality issue and can lead to frying.
Overpressure protection circuit and related devices malfunction:
If these devices fail to automatically stop heating under overpressure, this is another quality problem causing the fryer to fry its contents.
Lid not screwed into the locked position:
If the lid is not screwed into the locked position after being placed on the lid, the connection between the lid and the pot body is not secure, reducing the pressure-bearing capacity and potentially causing the lid to burst open under normal pressure. Some products are designed with a lid tightening safety switch, ensuring the lid is tightened before heating begins, effectively preventing this situation.
Rubber sealing ring aging and loosening:
Over time, the rubber sealing ring may loosen and enlarge, potentially bursting under high-pressure gas during normal operation. It is recommended to replace the rubber sealing ring of frequently used electric pressure cookers annually.
