What the dishwasher is detecting
The main control and the user interface exchange signals constantly. When the control stops receiving valid responses, or the control installed is not the type the display expects, this code is stored.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A loose connection between the user interface (display) and the main control.
- Documented A control that is the wrong type for this model's display, usually after a previous replacement.
- Possible A failed display/keypad board or communication circuit on the control.
Safe checks you can make
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
- If the control board was replaced recently, tell the technician, since a control that does not match the model can cause this code.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Inspects the connection between the display module and the main control.
- Verifies the control installed is the correct one for the model.
- Part of this diagnosis is a live low-voltage check on the control. This requires professional testing because the dishwasher has to be powered with its covers off.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher user interface / console replacement | $230–$550 | Moderate |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. If the console responds normally after a reset, the dishwasher can be used. A dead or erratic console needs service.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most 2-2 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
