Multicooker heats very slowly or never reaches the set temperature; food remains undercooked.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partially open main heating element, Loose heating element connectors, Faulty triac or relay not delivering full power, Incorrect voltage supply

How to Fix / Troubleshooting

Safety: Unplug the cooker and allow it to cool before accessing internal parts.

Step 1 – Basic test:

Run a high-heat program with water and time how long it takes to reach boiling.
If it never boils or takes excessively long, suspect heating issues.

Step 2 – Internal inspection:

Remove the bottom cover and locate the main heating element connections.
Check for loose spade connectors or signs of overheating.

Step 3 – Measure element resistance:

Disconnect the element and measure its resistance; compare with the specification for your Klarstein model.
A significantly higher resistance than normal indicates a failing element.

Step 4 – Repair:

Tighten or replace loose connectors.
Replace the main heating element if out of spec.
If the element is fine, the control board's triac/relay may be faulty; replace the main control PCB.
