What to check, in order
- Open both taps fully
GE's first question: were one or both supply valves left off after installation, or after coming back from holiday?
- Wait out the lock
The controls won't respond for 4 minutes. Unplugging the washer starts the 4 minutes again, so just wait, then start the cycle again.
- Clean the inlet screens
Turn the taps off and take the hoses off the back of the washer and off the taps. Clean the screens in the hoses (if fitted) and in the machine with a brush or a toothpick.
When to call an engineer
If the taps are fully open and the screens are clean but the message keeps coming back, GE recommends a service visit.
Good to know
- On front-loaders, GE says H2O SUPPLY can also mean a problem with the pressure sensor, or in rare cases extremely low water pressure. The washer then runs its drain pump for 4 minutes so it can't overfill.
Parts people end up buying
Only if the checks above point to a part. Match it to your model number first: it's on a label inside the door, around the door frame or on the back.
