Hobart Commercial Dishwasher Error Code Door Open: Door Not Closed
Door Open appears on a Hobart LXe dishwasher whenever the machine door is opened. Close the door and the message should clear. If it still shows with the door shut, open and close the door once more, and call us if it stays.
Low: a normal door status message; it clears when the door closes.

What does Hobart Door Open mean?
The LXe control watches a door switch. While the door is open, the machine will not run a cycle, and the display reads Door Open so the operator knows why nothing is starting. This is the machine behaving normally; it is only a status message tied to the position of the door. The manual's diagnostic table lists it simply as displayed when the door of the machine is opened. Its troubleshooting advice for a message that stays on with the door shut is to open and close the door again, which re-seats the door against its switch. A door that does not shut fully, a rack or tray catching the edge, or a door switch that is slow to register can leave the message on. If the door is closing properly and the message does not clear after the manual's open-and-close step, the switch or its wiring needs a technician, because the control is not receiving the closed signal.

Possible causes
Likely causes — what usually sits behind Door Open on this control. A technician confirms which one it is before any part is replaced.
- Door opened during or before a cycle
- A rack, tray or hose edge catching the door so it does not latch
- Door switch that is slow to register a closed door
- Door hinge or catch worn so the door sits slightly out of line
Safe checks before calling for service
- Remove anything caught at the door edge and push the door fully shut.
- Open and close the door once more, as the manual advises.
- Look for loose racks or items sticking out of the machine.
- If Door Open stays on, write down the model and tell us for the call.
How a technician diagnoses Door Open
- Check that the door aligns with the frame and the catch engages.
- Watch the display while opening and closing the door slowly.
- Test the door switch for continuity in both positions with the machine isolated.
- Inspect the switch wiring and connector at the control.
- Adjust or replace the switch and confirm a cycle starts.
- The door switch wiring is behind panels in a machine fed with 208-240 V and water.
- Testing the switch means isolating the machine and using a meter.
How Door Open differs from similar codes
Door Open is a status message; the machine's other messages, such as the sensor messages, ask for service.
