GE dishwashers talk in two dialects: newer models with a display spell out codes like PF and H2O, while older ones blink lights and beep in patterns. Both are worth listening to — a dishwasher lives closer to your flooring and cabinets than any other appliance, and its most serious codes are literally about water going where it shouldn’t. Here’s what the common GE signals mean in practice.
PF — power failure
The mildest one: the dishwasher lost power mid-thought and wants acknowledgment. Clear it and move on. Like every “power” code, it only matters when it repeats without an actual outage — that pattern points at a loose connection under the sink, a worn junction, or a control board browning out, and it’s worth catching before the machine dies mid-cycle for good.
H2O / no-fill signals — the dishwasher isn’t getting water
The machine started a cycle and the water didn’t arrive on schedule. Check the obvious once: the supply valve under the sink is open. Beyond that, the suspects are a failed water inlet valve, a kinked or clogged supply line, or a float switch stuck in the “already full” position. Running it dry repeatedly is how a $150 valve repair becomes a heating-element casualty, so if H2O returns after one valve check, stop cycling it.
Leak detected — take this one seriously
Many GE models carry a leak sensor in the base pan. When it trips, the dishwasher locks into a drain-and-stop routine to protect your floor — some models will even keep pumping until the pan is dry. This is the one GE code we’d call urgent every time: water is already outside the tub. The source is usually a door gasket, a cracked hose, a loose pump clamp, or a tub seal — findable and fixable, but not by running another cycle to “see if it does it again.” Shut the supply valve and get it looked at.
Blinking Start light / beeping every 30 seconds
Usually not a fault at all: a blinking Start light most often means the cycle was interrupted — a door opened mid-run or Start pressed twice — and the machine is waiting for the door to be closed firmly. If the door IS closed and the blinking continues, the door latch assembly or its switch has failed; the dishwasher refuses to run because it can’t confirm the door is sealed. A defined, inexpensive repair — and the same safety-interlock logic we see on washers and dryers.
Draining codes — covered separately
If your GE flashes FTD or simply stands in water, that’s the drain family — we broke it down (including GE’s own software-false-alarm bulletin) in our GE FTD guide. And if the machine runs fine but dishes come out dirty, that’s usually not a code at all: see dishwasher not cleaning.
Repair or replace?
Inlet valves, float switches, latches, gaskets, and pumps are all defined parts at a fraction of a new machine — on a GE that’s otherwise healthy, repair wins. The honest exception is a leak that’s been running quietly for months into the base and cabinet: by then the conversation includes what’s under the dishwasher, and we’ll give you the straight version of it.

GE dishwasher error codes — FAQ
My GE says “leak detected” but I don’t see any water. Is it a false alarm?
Sometimes — but don’t bet your floor on it. The sensor sits in the base pan under the tub, where a slow leak can pool long before it reaches daylight. A tripped leak sensor with a dry kitchen floor usually means the leak is small and early — which is exactly when it’s cheap to fix.
The Start light just blinks and nothing runs. Broken?
First close the door firmly and give it a few seconds — a blinking Start usually means an interrupted cycle waiting on the door. If it keeps blinking with the door closed, the latch or its switch has failed and the machine is refusing to run unsealed. That’s a quick, defined repair.
Do the same codes apply to my Café or GE Profile dishwasher?
Yes — Café, Profile, and Hotpoint dishwashers share GE platforms, so the signals and fault families carry over. Give us the brand, the code or blink pattern, and the model number, and we’ll map it to the right diagnosis.
How soon can you come out?
We run dishwasher calls across the Denver Metro throughout the week — and anything involving a leak gets priority. Call or book online and we’ll get you the soonest available window.
