Viking Combi Steam Oven Code EE02: absolute humidity sensor failure

What EE02 means

On the Viking Combi Steam/Convect ovens VCSO210 and CVCSO210 (2014 to 2016), such as the VCSO210SS, EE02 means the AH sensor has failed. AH stands for absolute humidity, and the sensor measures moisture in the cavity for sensor cooking. The code appears when the sensor circuit is broken or shorted, or when its readings fall outside the normal range. Sensor-based programs may stop, and the oven needs service.

Common causes of EE02

An AH sensor that has failed open or shorted
A sensor connection that has loosened
Sensor readings outside the normal range after damage or moisture
A control that cannot read the sensor

✓ One safe check you can try

1. Turn the oven off and wait for the cavity to cool. 2. Wipe the cavity and door seal dry so moisture does not collect. 3. Cut power at the plug for a moment, then restore it. 4. Try a plain timed cycle instead of a sensor program. 5. If EE02 returns, call us.

! Why to stop there

The humidity sensor is inside the oven and needs testing
Timed cooking may still work, but sensor programs will not
A wrong part order costs time

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.

EE02EE02 questions

What does the AH sensor do?

It measures the amount of water vapor in the oven so sensor programs know when food is done. EE02 means that reading is missing or out of range.

Can I still use the oven?

Plain timed cooking may still work, but we advise stopping if the code returns. Sensor programs will not run correctly until the sensor is replaced.

How is it repaired?

We test the sensor and its wiring, replace what has failed, and quote the price in writing before any work. Repairs carry a 30-day workmanship warranty from the day of the visit.
