Wolf GREASE OVERFLOW Error Code — Ventilation Fault Fix

Error Code Explained

What Does the Wolf GREASE OVERFLOW Error Code Mean?

A Wolf professional ventilation hood grease overflow occurs when the grease collection cup or tray beneath the grease filters has become full of accumulated cooking grease and overflows — causing grease to drip from the hood onto the cooking surface. This is a maintenance condition rather than an appliance failure, but an overflowing grease cup presents a fire hazard.

Root Causes

Common Causes of the Wolf GREASE OVERFLOW Error Code

1

Grease Collection Cup Not Emptied

The grease collection cup beneath the filters has filled with drip grease from cooking sessions and has not been emptied during routine maintenance.
2

Heavy Cooking Volume Between Maintenance

Intensive cooking with large amounts of grease-generating food has filled the grease cup faster than the typical maintenance interval.

Step-by-Step Guide

How to Troubleshoot the GREASE OVERFLOW Error Code

⚠️

Safety First: Always disconnect the Ventilation from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.

1

Empty and Clean the Grease Collection Cup

Remove the grease collection cup from beneath the grease filters. Empty the accumulated grease into a sealed container for disposal — never pour cooking grease down a drain. Wash the cup with hot soapy water and reinstall.
2

Clean the Filter Area

Clean any grease that has dripped onto the hood interior liner and cooking surface with a degreaser and soft cloth.

Empty the Wolf range hood grease collection cup at the same interval as you clean the grease filters — typically every 3–4 weeks under normal cooking use, or sooner after heavy frying or high-volume cooking sessions.
