Check: Confirm household water is on, fully open the supply valve, and straighten the inlet hose.
Est. cost: $0–$0
The valve solenoid can stick or fail after years of use, so the tub never fills.

Questions about H2O

H2O (sometimes shown as H20) means the dishwasher did not detect enough water. Confirm the inlet hose is not kinked and the supply valve is open.

H20 and H2O are the same low-water code. Open the supply valve and straighten the inlet hose, then run a cycle.
Why does my GE dishwasher keep showing H20?
The tub is still not filling. A kinked inlet hose or a closed valve makes H20 return after every reset.
How do I reset a GE dishwasher H20 error code?
Open the water supply, unplug for 5 minutes, and restart. H20 returns if the dishwasher still cannot fill.
How do I reset GE dishwasher H2O?
Unplug the dishwasher or switch it off at the breaker for 5 minutes, then restore power and restart. A reset clears a stored H2O after a glitch, but the code will return if the underlying fault is still present.
