What Does Error Code PrS Mean on a GE Appliances Dishwasher?

Pressure sensor fault — water level sensing issue.

PrS fires when the control board reads an out-of-range or absent signal from the analog water-level pressure sensor, which monitors sump fill via a small air-column hose. Unable to confirm the fill level, the board aborts or mis-fills the cycle. Unlike overfill or leak-related codes, PrS points specifically at the sensing path — a failed sensor, a pinched or clogged pressure hose, or a bad board input — rather than at valves or physical water levels themselves.

Models affected: GE tall-tub dishwashers with electronic pressure-based fill sensing, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS
What owners report: Owners commonly report PrS appearing at the start of a fill or shortly after a cycle begins, sometimes after cleaning the sump or a recent clog. In some cases debris or a kinked pressure hose is the false trigger, and clearing or reseating the hose resolves it before any sensor replacement is needed.

What Causes Error Code PrS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Pressure sensor failure 60% of cases
  2. 2
    Air trap or hose to sensor blocked 30% of cases
  3. 3
    Control board sensor input failure 10% of cases

How to Fix GE Appliances Dishwasher Error Code PrS

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check air trap and hose

    The pressure hose from the sump to the sensor should be clear.

  2. 2

    Test and replace sensor

    If hose is clear, test sensor and replace if failed.

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error PrS appears? +
You often can for a cycle or two, but the sensor issue behind PrS will keep interrupting normal operation until it is fixed. Plan the repair rather than ignoring the code.
What most commonly causes PrS on a GE Appliances Dishwasher? +
Across reported GE Appliances dishwasher repairs, the most frequent is pressure sensor failure (60% of cases), air trap or hose to sensor blocked (30%), then control board sensor input failure (10%). Check them in that order before replacing any parts.
PrS keeps coming back after a reset — what should I check next? +
A reset only clears the stored PrS fault; if it returns, the sensor problem is still present. Move on to the physical checks — check air trap and hose, then test and replace sensor — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix GE Appliances Dishwasher error PrS? +
A DIY repair typically runs $25–$60 in parts, versus $150–$280 for a professional service call, so handling it yourself saves around $125. Expect the work to take roughly 30–60 minutes.
Which GE Appliances Dishwasher models show error PrS? +
PrS is documented on GE tall-tub dishwashers with electronic pressure-based fill sensing, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
