What to check yourself
Step 1. Look at what is in front of the cup
Open the door and look straight at the dispenser. A tall pan on the lower rack, a sheet pan leaned against the door, or a spatula standing in the silverware basket is almost always the culprit. Move it and the code goes with it.
Step 2. Scrape out caked detergent
Powder that got damp turns to cement in the cup and stops the lid swinging. Pick it out, run a cycle with the cup empty and the lid open, and start filling it just before you run the machine rather than the night before.
Step 3. Check the lid latch by hand
With the door open, close the lid and press the release. It should spring open freely. A latch that sticks or a lid that no longer springs is the dispenser wearing out, and that is the one case where a part is needed.
What a technician will look at
Described so you know what you are paying for, not as steps to repeat.
Replace the dispenser assembly
The dispenser is one unit on the inside of the door, held by screws from the door's inner panel. The technician replaces the whole assembly rather than the latch alone.
When to call a technician
Only when nothing is blocking the lid and it still will not open on its own. That is a worn dispenser, and it is a small job, but the door panel comes apart to reach it.
What the repair costs
| Repair | Part only | Fitted by a technician |
|---|---|---|
| Moving the obstruction and cleaning the cup | - | Free |
| Dispenser assembly replacement | $50 to $105 | $75 to $200 |
A new machine of the same class runs $500 to $1,500. Once a quote passes about a third of that on an older appliance, the repair stops making sense.
Questions people ask
- The cup opened but the pod was still there at the end. Same thing?
- No code for that, but the same cause: something in front of the dispenser stopped the spray reaching it, or the pod stuck to a wet cup. Load the lower rack so the dispenser has clear space in front of it.
- Is Cup Open the same as C8?
- No. Cup Open on a current machine means you never latched the cup. C8 means the machine tried to open a latched cup and could not.
Which machines this applies to
Applies to
Older GE, GE Profile and Hotpoint dishwashers with electronic controls: GSD, GHD, PDW, EDW, GLD and HDA model prefixes. Current models show Cup Open instead when the cup was never closed.
