GE Dishwasher Error Codes — What They Mean & How to Fix Them

GE dishwashers show a “C” code (or, on models without a display, a flashing Clean light) when something’s wrong. Many are quick fixes you can do yourself. Here’s what each GE dishwasher code means, what to try first, and when to call a technician.

GE dishwasher error codes at a glance

Code	What it means	What to try
C1	Drain took too long (one cycle)	Clear the drain path and the air gap by the faucet
C2	Total drain time exceeded	Clear the drain hose; check the pump
C4	Refilled after a power loss (float stuck)	Check the float and clear debris in the sump
C7	Temperature / turbidity-sensor fault	Hard-reset at the breaker; may need service
FF	Control-board fault (all lights flashing)	Hard-reset at the breaker 1–5 min; service if it persists
Clean light blinking	Blink-pattern code (no display)	Count the blinks to identify the code

On models without a display, count the Clean-light blinks (e.g. 1 blink = C1). Codes vary by model.

The most common codes — and how to fix them

C1 / C2 — won’t drain

The dishwasher is taking too long to drain. Try first: clear the drain hose, clean the filter, and check the air gap by the sink for debris. Still stuck? See dishwasher not draining.

C4 — refilled after power loss

The dishwasher refilled twice, usually from a stuck float switch. Try first: check the float (front of the tub) moves freely and clear any debris in the sump.

C7 — sensor fault

A temperature or turbidity sensor problem. Try first: hard-reset by cutting power at the breaker for a few minutes. Returns? The sensor likely needs service.

FF — control-board fault

All lights flashing points to a control-board fault. Try first: a full breaker reset (1–5 minutes). If it comes back, the control board needs a technician.

The bottom line

Most dishwasher error codes come down to a clogged filter, a kinked hose, or an inexpensive part — repairing is almost always cheaper than replacing. If a code won’t clear, we repair GE dishwashers (and Hotpoint) (and every major brand) across DFW, usually same-day. Not sure yours is worth fixing? See our dishwasher repair-or-replace guide.
