Maytag Washer Error Code E42

E42 on a Maytag washer means the appliance failed to establish or maintain a network connection during a data transfer operation. It points to a problem in the communication chain between the washer's wireless module and your home network or connected service. The washer may still run normal wash cycles, but smart or connected features may be interrupted.

Yes, the E42 error is a networking fault and does not indicate a mechanical or electrical hazard with the wash system itself. The washer should still be capable of completing standard wash cycles. However, smart features that depend on network connectivity, such as remote monitoring or control, may not function until the error is resolved.

If the fix involves only network reconfiguration or repositioning the router, there is no parts cost. If the internal Wi-Fi communication module needs replacement, parts and labor costs typically range from around $100 to $250 depending on the technician and part availability. Main control board replacement, if required, can range from $200 to $450 or more including labor.

Start by checking your home Wi-Fi network to confirm it is online and that the signal reaches the washer's location. If the network is fine, try re-pairing the washer to your router using the connected app or the washer's settings menu. If the error persists, inspect the internal Wi-Fi module and its wiring for damage, and consider whether the main control board may need evaluation.

A reset may temporarily clear the E42 code, but if the underlying network or hardware issue is not resolved, the error is likely to return. Power cycling the washer and your router together is a reasonable first step. For a lasting fix, address the root cause such as signal strength, network credentials, or a faulty Wi-Fi module.
