GE Dishwasher C3 Error: Dishwasher will not drain
This guide covers GE dishwasher C3 error in detail to help you diagnose and resolve the issue. What Does GE Dishwasher Error Code C3 Mean? Error code C3 is the most severe drain fault in GE’s C-series code set. It means the dishwasher detected a complete drain failure — no water movement was registered during […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A completely undrained dishwasher is a water damage risk and a hygiene hazard. Do not attempt to run a wash cycle until the C3 fault is fully resolved and the tub drains completely.
Can I reset the code?
Yes. The C3 code clears when a successful drain cycle completes. Press Cancel/Drain after removing any obstruction. If the tub empties, the fault resets automatically. If the pump is dead, the code will not clear without replacing the pump.
When to stop immediately?
Stop if you notice: Water is overflowing onto the floor from the door seal, You detect a burning or electrical smell near the dishwasher.
Symptoms You May Notice
Tub completely full of water, door leaks on opening
Opening the door reveals a tub filled to or near the door seal level. Water may spill onto the floor. The dishwasher has not removed any wash water.
C3 displayed and all cycle lights off
The control panel shows "C3" and the machine is fully locked out — no cycle selection is possible until the error is resolved and cleared.
Drain pump is silent during drain phase
Unlike C1/C2 where the pump runs but is too slow, C3 often means the pump is not activating at all — no motor hum is heard when the dishwasher attempts to drain.
Foul odor from standing water
Wash water sitting in the tub for an extended period develops an unpleasant smell from food debris decomposition, making the problem impossible to ignore.
Possible Causes
Completely blocked drain filter or sump
A solid blockage — such as a broken glass shard, large food item, or accumulated grease plug — can prevent any water from reaching the drain pump inlet.
DIY PossibleFailed drain pump motor
A seized or burned-out drain pump motor will not activate at all, causing a complete drain failure. The pump may hum briefly and then go silent as a thermal protector trips.
Requires ProfessionalDrain hose completely blocked or disconnected
The drain hose may have come loose at the sink drain connection, developed a severe kink, or become completely blocked by a grease plug, preventing any water from exiting the tub.
DIY PossibleSafe Checks You Can Do
-
1
Manually remove standing water
Use a cup and absorbent towels to remove as much standing water from the tub as possible before attempting repairs. This prevents spills and allows you to access the filter and sump safely.
Place old towels on the floor in front of the dishwasher before opening the door to catch any water that spills out.

2
Check and clear the filter and drain hose
Remove the lower rack and the filter assembly. Look into the sump cavity for any solid obstruction (broken glass, food chunks, twist-ties). Trace the drain hose from the back of the unit to the sink drain — confirm it is connected, unkinked, and clear.
Wear rubber gloves when reaching into the sump — broken glass is a common hidden cause of complete drain failure.

3
Attempt a Cancel/Drain cycle after clearing
After removing any visible obstruction, press Cancel/Drain and listen for the pump motor. If you hear humming and water begins to move, the blockage was the cause. If silent, turn off the breaker — the pump requires professional evaluation.
Do not run multiple drain cycles if the pump is silent — this can cause the pump motor to overheat.
When to Call a Professional
Contact a qualified technician if:
- No obstruction found but drain pump remains silent — motor failure confirmed
- Drain hose and filter are clear, yet C3 returns on every cycle
- Control board displays additional fault codes alongside C3
