Viking Combi Steam Oven Code EE01: oven thermistor failure

What EE01 means

On the Viking Combi Steam/Convect ovens VCSO210 and CVCSO210 (2014 to 2016), such as the VCSO210SS, EE01 means an oven thermistor failure. The thermistor measures the oven temperature, and EE01 appears when its circuit is broken or shorted. With no valid reading the control cannot regulate heat, so the oven stops. The display shows EE01 and the oven needs a technician to test and replace the sensor.

Common causes of EE01

An oven thermistor that has broken or shorted
A thermistor wire or plug that has been damaged
A control that can no longer read the thermistor

✓ One safe check you can try

1. Switch the oven off and let it cool. 2. Disconnect the power cord for a short wait, then reconnect it. 3. Try one short steam or convection cycle. 4. If EE01 returns, stop using the oven. 5. Call us and give us the code and the model number.

! Why to stop there

The thermistor sits inside the oven and needs a meter to test
Without a temperature reading the oven cannot heat safely
Parts and testing must match the exact model

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

EE01EE01 questions

What is a thermistor?

It is a temperature sensor whose resistance changes with heat. The control reads it to hold the oven at the set temperature. EE01 says that reading is lost.

Can I keep cooking without it?

We recommend not cooking. Without a valid reading the oven cannot control heat, so the safe choice is to stop and have the sensor tested before the next cycle.

What does the repair involve?

We test the thermistor and its wiring, replace whatever has failed, and quote the price in writing first. Repairs carry a 30-day workmanship warranty from the day of the visit.
