GE Profile Dishwasher F10 Fix (Error Code Guide)

Here’s the factory-approved playbook, minus the fluff.

• Kill power first. Flip the dishwasher breaker off. You don’t poke around live wiring on a wet machine.
• Confirm the water is actually on. Under the sink, find the dishwasher shutoff valve. Turn it fully counter-clockwise. Make sure nobody half-closed it.
• Check the supply line for kinks. The braided hose from the shutoff to the dishwasher can get crushed when someone stuffs cleaning bottles under the sink. Straighten any sharp bends.
• Clean the inlet screen at the valve.
  • Shut off the water at the under-sink valve.
  • Remove the lower toe-kick panel on the dishwasher.
  • Find the water inlet valve where the supply line connects.
  • Put a towel under it, disconnect the line, and look for a tiny mesh screen in the valve inlet.
  • Rinse the screen clear of sand, rust, or scale. Toothbrush, not a screwdriver.
  • Reconnect the line, snug but not gorilla-tight, and turn the water back on. Check for leaks.
• Make sure the float isn’t stuck “full.”
  • Open the door and look in the front corner of the tub for a small plastic float or dome.
  • Move it up and down. It should travel freely and you should hear a faint click from the float switch.
  • If it’s jammed with soap crud or a utensil, clean it and free it up. If the float is stuck up, the board thinks the tub is already full and won’t let water in.
• Run a quick test fill.
  • Restore power at the breaker.
  • Start a normal cycle and close the door fully.
  • Let it run 1–2 minutes, then open the door mid-cycle.
  • You should see 1/2–1 inch of water over the filter area, not a dry bottom.
  • If it’s still bone dry or just a puddle and F10 pops again, the water inlet valve or the water level sensing circuit is likely bad.
• When to stop and swap parts.
  • If you have good water pressure at the under-sink valve and the hose is clear, but the dishwasher barely fills or throws F10 every time, the inlet valve is the first suspect.
  • If it does fill with a decent amount of water but still tosses F10, the float switch or the main control board may not be reading the water level correctly.
  • At that point the “official” fix is replacing the bad component and clearing the code by running a fresh cycle.
