GE Dishwasher Error Code Start

The Start error on a GE dishwasher signals a communications failure between the User Interface control board and the main machine control board. When these two boards cannot exchange data, the dishwasher cannot process commands or run cycles. The fault is typically caused by a wiring issue between the two boards, though a failed board is also possible. Checking the wiring harness and the main board service LED are the recommended first diagnostic steps.

A reset, typically performed by cutting power to the dishwasher at the circuit breaker for a minute or two, may temporarily clear the error if the communication failure was caused by a one-time software glitch. However, if the underlying cause is a physical wiring fault or a damaged board, the error will return once the dishwasher attempts to communicate again. A reset is a reasonable first step, but a recurring error requires hands-on diagnosis.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, a service call fee of roughly 75 to 150 dollars may be the only expense. Replacing a wiring harness typically adds 30 to 80 dollars in parts. A new UI board or main control board can range from 100 to 300 dollars or more in parts alone, plus labor, making board replacements the more costly outcome.

A knowledgeable DIYer can attempt to diagnose and fix this error by inspecting the wiring harness between the UI control and the main control board for loose connectors, visible damage, or corroded terminals. Reseating connectors firmly is a straightforward fix that requires no parts. However, if the boards themselves need to be replaced, the repair requires some comfort with appliance disassembly and working around electrical components.

No, the dishwasher will not run a cycle while this error is active because the control boards cannot communicate well enough to coordinate operation. Attempting to use the appliance in this state is not productive, and running it with damaged wiring near water-handling components is not advisable. The fault should be diagnosed and resolved before returning the unit to regular use.
