Frigidaire Dishwasher Error Code E42: How to Fix It

Q: Why does my Frigidaire dishwasher show E42 even when the door is closed?

Error E42 can appear even with a closed door due to a faulty door switch, worn latch mechanism, misaligned door, or loose wiring connections. The dishwasher's safety system can't detect that the door is properly secured, triggering the error code.

Q: Can I reset Frigidaire dishwasher error code E42?

You can try resetting the error by unplugging the dishwasher for 5 minutes, then plugging it back in. However, if the underlying door switch problem isn't fixed, the E42 error will return when you try to start a wash cycle.

Q: How much does it cost to fix Frigidaire E42 error?

DIY repair costs range from $20-80 for a replacement door latch assembly. Professional repair typically costs $150-300 including parts and labor. The exact cost depends on your specific Frigidaire dishwasher model and local service rates.

Q: Is it safe to use my dishwasher with E42 error?

No, you should not use your dishwasher with error code E42. This error indicates the door safety system isn't working properly, which could allow the dishwasher to operate with an unlocked door, creating safety hazards including water leakage and exposure to hot water and steam.

Q: How long do Frigidaire dishwasher door latches last?

Frigidaire dishwasher door latches typically last 8-12 years with normal use. Heavy use, frequent door slamming, or exposure to hard water minerals can reduce lifespan. Signs of wear include difficulty latching, loose door feel, or intermittent E42 errors.
