What does Unox WF36 mean?
WF36 is a warning for lack of water or a fault in valve EL1 or EG1/EG2. The oven is not getting the water it needs, either from the supply or because one of these valves is not delivering. As a warning it continues with limited water-dependent function while flagging the problem.
Symptoms
- WF36 warning on the control panel
- Insufficient or no water/steam
- Affected valve not delivering water
- Warning recurs when water is requested
Common causes
- Water supply off or low pressure
- Clogged filter or inlet
- Valve EL1 or EG1/EG2 stuck or faulty
- Wiring fault to a valve
- Scale or blockage in a valve

Diagnostic steps
Check the water supply
Confirm the water tap is open and at adequate pressure.
Inspect filter and line
Check the inlet filter and water line for blockage or kinks.
Test the valves
With power off, verify EL1 and EG1/EG2 actuate and are not stuck or scaled.
Repair or replace
Restore faulty wiring and replace any valve that does not operate, then retest.
When to call a professional
WF36 begins with operator checks of the water supply and filter. If water is present and a valve still fails, isolating and replacing the solenoid valve is electrical and plumbing work for a qualified Unox technician.
