What F2-03 / F3-03 Means
F2-03 and F3-03 are general software errors on the power board of a DCS WOSV230 or WODV230 oven, the power-board counterpart of F1-03. The service manual’s remedy is a power reset, then a power board replacement if it persists.
Common Causes of F2-03 / F3-03
- Software glitch after a power interruption
- Power board memory or processor failing
🔧 One Safe Check You Can Try
With the oven cool, cycle the breaker off for a minute and on again. Keep track of whether the code returns; a one-time error after a storm needs no repair.
⚠ Why You Shouldn't Go Further Than That
- Power boards are replaced and then matched to the oven’s model ID in technician mode.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
