What does Unox WF35 mean?
WF35 is a warning indicating a fault with valve EG1, EG2 or EL2 in the oven's water/steam circuit. One of these valves is not operating correctly. As a warning the oven keeps running with reduced function while flagging that one of these valves needs service.
Symptoms
- WF35 warning on the control panel
- Steam or water function impaired
- A valve (EG1, EG2 or EL2) not actuating
- Warning recurs during the affected cycle
Common causes
- One of valves EG1, EG2 or EL2 stuck or faulty
- Valve coil failure
- Wiring fault to the valve
- Scale or blockage in the valve
Diagnostic steps
- 01
Power down and locate the valves
Turn off power and identify valves EG1, EG2 and EL2.
- 02
Test each valve
Verify each valve actuates when energised and is not blocked.
- 03
Measure coils and wiring
Check the valve coils and wiring with a multimeter to isolate the faulty valve.
- 04
Replace the faulty valve

When to call a professional
WF35 spans three solenoid valves, so isolating the faulty one takes methodical testing. Replacing the valve is electrical and plumbing work for a qualified Unox technician if a basic check does not resolve the warning.
