GE GTWN7450D0WW Top Load Washer display says "H2O Supply"

From www.justanswer...
JustAnswer Customer: GE GTWN7450D0WW Top Load Washer display says "H2O Supply" and hums.
JustAnswer Customer: Washer won't run.
JustAnswer Customer: Display says "H2O Supply" and sounds like it's trying to pump out; water is on, household water supply is good.
JustAnswer Customer: Tried unplugging and leaving out for awhile to reset controls but just does same thing once I plug it back in.
JustAnswer Customer: Anyone ever have this issue, or know what could cause it?
JustAnswer Customer: Tired of paying the GE tech to fix this thing!
JustAnswer Customer: Thanks.
AppTech8579: Home Appliance Technician: Remove the hoses from the washer and place in a bucket and turn on the water.
JustAnswer Customer: Did that, water supply shuts off and on fine.
AppTech8579: Home Appliance Technician: With good water pressure then you have a faulty circuit board that needs replaced.
JustAnswer Customer: So there are no other inputs to that logic I should check?
JustAnswer Customer: A pressure switch, drain valve, etc.?
JustAnswer Customer: Is it worth pulling out and reconnecting the cards?
AppTech8579: Home Appliance Technician: There is a problem with the water supply.
AppTech8579: Home Appliance Technician: You can check the pressure switch.
AppTech8579: Home Appliance Technician: Also turn off the water, unplug the unit.
AppTech8579: Home Appliance Technician: Plug the unit back in and turn on the water supply.
AppTech8579: Home Appliance Technician: I see this question is still open.
AppTech8579: Home Appliance Technician: Do you need more help?
AppTech8579: Home Appliance Technician: Post back here with anymore questions.
AppTech8579: Home Appliance Technician: Thanks.
JustAnswer Customer: The washer is now fixed.
JustAnswer Customer: It appears the controls froze up and locked themselves for whatever reason.
JustAnswer Customer: Here is what I did: I located the mini manual inside the washer, and got the instructions to get the washer into service mode.
JustAnswer Customer: I did have to unlock the controls as it appeared they locked themselves when they froze up.
JustAnswer Customer: I pushed the buttons and turned the dials as instructed to get the controls in service mode, which seemed to work fine.
JustAnswer Customer: I ran through all the diagnostics, found no issues or error codes, or anything else unusual.
JustAnswer Customer: When I exited service mode, the controls reset and worked normally.
JustAnswer Customer: So no bad circuit board, no visit from the appliance tech required.
JustAnswer Customer: Maybe you could use my experience to help the next guy.
AppTech8579: Home Appliance Technician: Glad you got it sorted.
AppTech8579: Home Appliance Technician: I see this question is still open.
AppTech8579: Home Appliance Technician: Do you need more help?

Thanks , retired housewife and on fixed income new washers are way to0 complicated. I have been searching for a fix for this prolblem. I watched until the end and the recommendation at the end from the original inquirer fixed the problem. Thanks no need to call a repairman. I am so ,so ,so grateful.

I found that my cold-water hose was 'somewhat' restricted. I connected it to an outdoor hose bib and forced water through the hose. That seemed to free-up the water flow through the hose. Additionally, my vacuum line to the pressure switch had come disconnected. I reconnected it also. Then I located and retrieved the document in the plastic bag fastened to the inside of the cabinet on the left side. 'Lots" of repair help on that document!

Hello. 2 men came out and can't figure out why it still says h2o supply on panel. The machine isn't spinning all the water out and it's frustrating. The washer isn't more than 1 yr old.

if anyone needs help i had to not only clear the drains of clogs, but unplug the machine and restart the cycle.

[@stricdog]

fix the water supply, then plug it in; wait 4 minutes for the cycle and change the cycle w main wheel; then it will reset
