The flashing C5 error code on your GE dishwasher indicates frustration – your dishes are dirty and the washer isn’t working properly. This common issue occurs when the dishwasher fails to fill with enough water.
By carefully troubleshooting the potential causes, from low water pressure to faulty valves to leaks, you can identify the root problem and fix it.
This article provides an overview of the C5 error and guides you step-by-step through diagnosis and repair. Let’s get started resolving the issue and putting your dishwasher back in washing action!
Understanding the C5 Error Code
The C5 error code on a GE dishwasher indicates there is an issue with the water filling process during a wash cycle. Let’s break down what exactly this error means.
Definition of the C5 error code
The C5 error code alerts you that the dishwasher is not filling properly with water. It commonly appears about 2 minutes into the cycle, when the dishwasher should be finished filling.
Seeing a C5 error means:
- The dishwasher is not detecting the right water level at the expected time. This triggers the control board to shut off the cycle.
- There is likely an issue with the water supply, input parts, or detection system.
- The dishwasher cannot proceed with washing dishes until the error is fixed.
Insufficient water levels during the cycle
When the C5 error pops up, it means the dishwasher isn’t filling with enough water as programmed.
Here’s a quick overview of what should happen in normal operation:
- The cycle starts, and the water inlet valve opens to allow water to enter the tub.
- Water fills to the level needed for that specific wash cycle. This takes about 2 minutes.
- The pressure switch or water level sensor detects the right amount of water.
- The control board gets the signal that it’s OK to proceed.
With the C5 error, step 3 does not happen as expected. The water level is too low when the control board checks it. This causes the C5 code to display.
Potential Causes of the Error
Now that we know what the C5 error code means, let’s explore some possible reasons it could show up. Pinpointing the cause is key to fixing your GE dishwasher.
A. Low water pressure or partially closed water supply valve
One of the most common reasons for the C5 error is that water can’t flow properly into the dishwasher. Some examples include:
- Your home’s water pressure dropped lower than needed for the dishwasher to fill right.
- The water supply valve under the sink is partially closed or blocked.
- The water supply line is kinked or crimped.
- Sediment or minerals clogged the water inlet filter screen.
Do you notice low flow from other faucets? That’s a sign of an overall water pressure issue.
B. Malfunctioning water inlet valve
The water inlet valve controls water flow into the dishwasher. It’s an electrical part that opens and closes based on signals from the control board.
If this valve is broken, it could cause the C5 error in a few ways:
- It may not open at all, blocking all water from entering.
- It may open partially, restricting how much water gets in.
- It may not close properly once the tub is full.
Testing the valve is the best way to see if it’s the culprit. We’ll cover how a bit later.
C. Leaks in the dishwasher tub or door gasket
Leaks allow water to escape and prevent proper filling:
- Door gasket leaks – if the main door seal is damaged, water can seep out from the edges.
- Tub leaks – cracks or holes in the tub allow water to leak out before it reaches the right level.
Inspect the dishwasher carefully to find any leaks. You may see water on the floor under the unit.
D. Clogged pump inlet
Food debris getting clogged in the pump inlet screen can block water from properly circulating during the fill process. Make sure to clean out the pump filter regularly.
E. Leaky diverter valve
This small valve routes water to the right areas. If it leaks internally, it reduces overall water pressure.
Tools You’ll Need
When troubleshooting a C5 error code on your GE dishwasher, having the right tools on hand will make the process much smoother. Here’s a list of handy tools to have ready:
Screwdrivers
You’ll need both Phillips and flathead screwdrivers in various sizes. Some key things you may need to unscrew and access include:

The first thing to check is the water supply valve. This valve is usually located under the sink and controls water flow to the dishwasher.
To check it:
- Locate the water supply valve under the sink.
- Make sure the valve is fully open.
- Check for kinks in the water supply line.
Are you getting a full stream of water through the valve? If not, the valve could be clogged or partially closed, reducing water flow.
Test Water Inlet Valve
The water inlet valve controls water flow into the dishwasher tub. Use a multimeter to test it:
- Unplug the dishwasher and disconnect the valve wires.
- Set a multimeter to test for continuity.
- Touch probes to valve wires. The multimeter should show continuity if the valve is okay.
- If there is no continuity, the valve is faulty and needs replacing.
Did you know multimeters let you test electrical parts without power? Cool!
Examine Dishwasher Tub and Door Gasket for Leaks
Check around the tub and door for leaks:
- Run a cycle and check for leaks around the door gasket.
- Inspect the dishwasher tub for cracks or holes.
Even small leaks can interfere with properly filling the tub with water.
See any leaks or damage? The gasket or tub may need replacing.
Clear Any Debris or Clogs from the Pump Inlet
A clogged pump inlet can trigger the C5 code, too. To inspect:
- Remove the lower access panel to expose the pump.
- Check for blockages at the pump inlet.
- Use a toothbrush to clean out any debris.
Did you find any food bits or broken glass blocking the inlet? Clear the clog!
Test Diverter Valve
The diverter valve routes water into the tub. Test it with a multimeter:
- Remove power and disconnect valve wires.
- Check for continuity when switching valve positions.
- No continuity means the valve is faulty.
