Unox WF26

What does Unox WF26 mean?

WF26 is a warning related to rotor valve EG2 in the oven's water/steam circuit. The control has detected that valve EG2 is not operating correctly. As a warning the oven continues with restricted function while indicating this valve needs service.

Symptoms

• WF26 warning on the control panel
• Steam or rotor function impaired
• Valve EG2 not actuating on command
• Warning recurs during the affected cycle

Common causes

• Rotor valve EG2 stuck or faulty
• Valve coil failure
• Wiring fault to EG2
• Scale or blockage in the valve

Diagnostic steps

1. 01

   Power down and locate EG2

   Turn off power and identify rotor valve EG2 in the water/steam circuit.

2. 02

   Check valve operation

   Verify EG2 actuates when energised and is not blocked by scale.

3. 03

   Test coil and wiring

   Measure the valve coil and check the wiring with a multimeter.

4. 04

   Replace the valve

   Replace rotor valve EG2 if it does not operate correctly and retest.

When to call a professional

WF26 concerns a steam-circuit solenoid valve. Testing the coil, wiring and replacing the valve is electrical and plumbing work for a qualified Unox technician if a basic check does not clear the warning.
