Why Won't My Multicooker Turn On?

Aug 06, 2023, 17:49pm

The multicooker (of which the Cookeo brand is the most common) is a kitchen appliance that can have multiple cooking possibilities: steam cooker, cooker, rice cooker, slow cooker or fryer.

It is possible that the multicooker no longer turns on, in this case, you will have to check:

  • the power outlet
  • the electrical panel
  • the power cord
  • the condensate collector
  • the display card
  • the thermostat
  • the thermal fuse
  • the power card

A multicooker is a versatile kitchen appliance that makes meal preparation easier. But, like any device, it can occasionally present challenges, such as refusing to turn on. If you’re facing this issue, don’t worry, as there are several reasons why this might be happening, and many can be addressed without the need for a professional. Here are some potential reasons why your multicooker won’t turn on, along with the solutions to fix them.

Why Won't My Multicooker Turn On?

Reason 1: Power Supply Problems

The simplest explanation for a multicooker not turning on is that it’s not getting any power. The socket, plug, or cord could be faulty, or your circuit breaker could have tripped.

Solution: Ensure the multicooker is properly plugged in and the power switch is on. Test the socket using another appliance. If the other device works but the multicooker doesn’t, the problem might lie in the multicooker’s plug or cord, and you might need a technician to check it.

Reason 2: Faulty Power Button or Control Panel

A faulty power button or control panel could be another reason why your multicooker isn’t turning on. Over time, buttons can wear out, or the electronics within the control panel can fail.

Solution: If your power button isn’t responding, or if the control panel doesn’t light up or respond, you might need to replace these components. Because this involves working with the multicooker’s electronics, it’s safer to have this done by a professional.

Reason 3: Internal Fuse Has Blown

Multicookers often have an internal fuse that can blow if the appliance overheats. This is a safety feature designed to prevent fire hazards, but it can also cause your multicooker to not turn on.

Solution: If you suspect that your multicooker’s fuse has blown, consult a professional repair service. Handling electrical components can be dangerous if you don’t have the right expertise.

Reason 4: Worn-out or Damaged Components

Over time and with frequent use, components within your multicooker can wear out or become damaged, causing it to stop working entirely.

Solution: If the multicooker is old and has been regularly malfunctioning, it may be more cost-effective to replace it. When purchasing a new multicooker, look for models with strong warranties, good durability, and positive customer reviews.


Your condensate collector may be full.

  • Check if there is still water in the collector, in which case it is necessary to drain it and restart the multicooker.
  • Remember to empty the heat exchanger after each cooking. Lift the lid up so the trap can draw water.

The thermostat makes it possible to regulate the resistance heating by modes and turn it off in case of overheating. It is located under your device.

  • Then remove the screw and then the plate that supports the bottom of your appliance, then remove the multicooker base.
  • Place the multimeter on the continuity gauge or the lowest value in ohms.
  • Place the black probe of the multimeter inside the phase wire of the thermostat. Place the other red tip on the blue phase on the electronic map.

If there is no sound signal, the thermostat will have to be changed.


The power board will power your multicooker and other elements such as thermostat, pot sensor, etc.

  • Check the power card for burns. It is located like all other elements under the multicooker, after unscrewing the bottom plate.
  • When you find the power board in front of you, you will need to remove the two screws that hold it to the support.
  • On the left side of your e-card, remove the 3 black and white connectors.
  • Take a multimeter and put it on a continuity gauge or the smallest resistance gauge.
  • Place two multimeter tips on one of the pins on your electronic card.
  • If there is no beep, it means that the card is faulty. Repeat measurement with other terminals.


A multicooker that won’t turn on can be a significant inconvenience, especially if you’re in the middle of meal preparation. However, understanding the potential causes can help you diagnose the problem and take appropriate action, whether that’s basic troubleshooting or calling in a professional. Regular maintenance and proper use can also prevent many common problems and extend the lifespan of your multicooker.
