GE Dishwasher FTD Error in Westchase: A Pressure Sensor Fix

A GE dishwasher in Westchase (model GDF640HSM5SS) kept throwing an FTD error — a drain-related fault code. There was no water sitting in the tub, so the obvious drain-clog explanation didn’t hold up.

Chasing down an FTD code with no water in sight

Powering it on, the dishwasher would start draining for about a minute and then fault out with the same error. That pattern points less at an actual drain blockage and more at the system failing to correctly read how much water is in the tub in the first place.

The usual suspect

On this kind of fault, the water-level pressure sensor is the cause roughly 90% of the time — the control board is a rare exception. Sure enough, the sensor had failed here too.

Fixed and tested on the spot

I keep this sensor stocked in the truck since it’s such a common failure — GE deserves some credit here, too. Unlike some brands that scatter dishwasher sensors across a dozen part numbers, GE keeps it to just a handful of positions across their lineup, which makes carrying the right part a lot more realistic.

With the new sensor in, I ran it through every cycle to confirm it was reading correctly before buttoning it back up. Everything checked out, and the client was glad to have it done in one visit.

If your dishwasher is throwing a drain-related error but there’s no water actually sitting inside, a failed pressure sensor is worth checking before assuming the drain line itself is clogged. See our dishwasher repair page for what else we typically look at.
