GDT645SYNFS GE dishwasher H2O error code


Mar 19, 2023
Philadelphia, PA
Model Number
1-5 years
I used to get the H2O error code sporadically but now the thing has become constant and the dishwasher throws the error each time. Here are the steps I have tried:

1. Checked that the water is getting into the system. I could hear it and the water accumulates inside the dishwasher. No kinks in the inlet. I took the dishwasher out and the inlet hose. Held the hose to a bucket to be extra sure.

2. Checked the pressure sensor as per this thread. I did find some accumulation inside the sensor. So I cleaned it out but that didn't solve the problem.

What other steps can I try? Replace the pressure sensor? Any suggestions will be very helpful. Thanks in advance.

Hi Shane,

The pressure sensor monitors the water level, replace the pressure sensor.

Here's the pressure sensor for your model:
