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

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.
