Blakeslee Commercial Dishwasher Signal SHUT HOOD: Hood Open
SHUT HOOD is a signal, not a breakdown alarm. It appears when an operation was tried that cannot be done with the hood open, or when the hood was opened and interrupted a running cycle. Close the hood and the machine can continue.
Low: an operator signal that clears when the hood is closed.

What does Blakeslee SHUT HOOD mean?
A hood-type dishwasher has a hood that must be down for a cycle to run, because hot spray and steam are released inside. The control watches the hood position. If someone presses a function that needs the hood closed while it is open, or if the hood is lifted during a running cycle, the display shows SHUT HOOD. The manual lists it under Signals and gives one action: close the hood. It is an operator prompt, so no part has failed, and the message goes away once the hood is down and detected. Many of these events happen when racks are loaded and the hood is left slightly raised, or when a cycle is interrupted to add a rack. If the hood is down and the signal persists, the hood sensor or its switch may not be reporting properly.
Affected models and control systems
Blakeslee D-18D / D-18V digital-control hood-type dishwasher. The manual's cover prints D-19 L and D-19 LRS and names no D-18 model, so the signal list is read as covering this hood-type family.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice

Possible causes
Likely causes — what usually sits behind SHUT HOOD on this control. A technician confirms which one it is before any part is replaced.
- An operation was tried that cannot be done with the hood open
- The hood was opened and interrupted a running cycle
- Hood not pushed fully down so its switch is not made
- Hood switch or magnet misaligned
- Rack catching the hood frame so it sits slightly open
Safe checks before calling for service
- Close the hood fully, as the manual says.
- Check that no rack or tray is holding the hood up.
- Start the cycle again.
- Wait for the signal to clear.
- If SHUT HOOD stays with the hood down, note it and tell the service technician.
How a technician diagnoses SHUT HOOD
- Confirm SHUT HOOD and ask what the operator was doing.
- Check the hood sits flush and its balance mechanism works.
- Inspect the hood switch and its actuator.
- Watch the hood input change as the hood closes.
- Adjust or replace the switch and confirm a cycle runs.
- The hood switch is a safety interlock and must not be bypassed.
- Its wiring connects to line-voltage controls.
- Adjusting the switch can involve removing a cover near live wiring.
How SHUT HOOD differs from similar codes
