Unox WF37

What does Unox WF37 mean?

WF37 is a warning for lack of water or a fault in valve EL1 or EG1/EG2, closely related to WF36. The oven is not receiving the water it expects through these valves. As a warning it continues with limited water-dependent function while flagging the supply or valve problem.

Symptoms

• WF37 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

1. 01

   Check the water supply

   Confirm the water tap is open and at adequate pressure.

2. 02

   Inspect filter and line

   Check the inlet filter and water line for blockage or kinks.

3. 03

   Test the valves

   With power off, verify EL1 and EG1/EG2 actuate and are not stuck or scaled.

4. 04

   Repair or replace

   Restore faulty wiring and replace any valve that does not operate, then retest.

When to call a professional

WF37 starts with operator checks of supply and filter. If water is present and a valve still fails, testing and replacing the solenoid valve is electrical and plumbing work for a qualified Unox technician.
