Symptoms
- A number, letter, or blinking light pattern displays
- Cycle won't start or stops with the code showing
- Beeping accompanies the code
- Code repeats after clearing it once
Likely causes
- CommonDoor or latch sensor faultCodes related to the door are among the most common and often just need a firmer close.
- CommonWater fill or drain sensor faultThe unit can flag a code when it doesn't detect expected water flow within its timeout window.
- PossibleHeating element or thermistor faultA failed heating sensor can trigger a temperature-related code.
- PossibleCommunication or control board faultSome codes indicate an internal communication error between components.
- Less commonSensor genuinely failedAfter ruling out simple causes, a specific sensor may need replacement.
What to do
- Write down the exact code, number, or blink pattern shown.
- Look up that specific code for your dishwasher's brand and model online or in the manual, since codes are not standardized across brands.
- Check the door latch and water supply as these are common triggers for many codes.
- Power-cycle the unit by turning off the breaker for one minute to see if the code clears.
- Run a normal cycle and see if the code returns at the same step each time.
- If the exact code points to a specific part (like a heating sensor) and the issue persists, contact a technician with that code in hand for a faster repair.
Tools and parts
- None
When to call a pro
If a code returns consistently after a reset, share the exact code with an appliance technician so they can target the right part.
