GE Dishwasher PR5 Error Code: Pressure Sensor Fault

Quick Answer

The GE dishwasher PR5 error indicates a fault in the pressure switch circuit used to monitor water level. PR5 and FED both trace back to the same pressure switch component WD01X24700. The difference is that PR5 fires as a circuit-level fault rather than an end-of-cycle drainage confirmation failure.

PR5 usually pops up right as the machine tries to fill or kick off the wash cycle. The control board's getting a garbage signal from the pressure sensor and shuts everything down to prevent an overflow. Nine times out of ten it's either a loose rubber air tube (two minutes to fix, costs nothing) or a dead $25 switch. Don't ignore it. A dishwasher that can't confirm water level will eventually flood your kitchen floor.

What Does the PR5 Code Mean?

GE's pressure switch on these models is actually pretty reliable. But that little rubber air tube connecting it to the sump? It's basically just held on by friction, and after a few years of vibration it works itself loose. I've probably knocked out six or seven PR5 calls in the last couple months and most of them were just that tube popped off its port. The part itself is cheap and this is genuinely one of the more DIY-friendly dishwasher repairs you'll run into.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Pressure switch internal contact failure40%

Air tube disconnected or cracked causing false pressure reading24%

Wiring harness from switch to control board damaged22%

Air tube blocked with water or debris14%

Symptoms You May Notice

PR5 flashes on the display either right when you hit Start or within the first 60-90 seconds while the tub's trying to fill.
Machine just sits there. Doesn't drain, doesn't fill, doesn't do anything. Door's locked, just showing the code.
Sometimes you'll hear the fill valve click open for a couple seconds, then everything stops cold and PR5 comes up.
Cycle won't advance past the fill phase no matter how many times you hit Start or Cancel and try again.
On some units it'll reset itself and try one more time, then lock out permanently with PR5 after the second failed attempt.

Can you reset a Ge dishwasher to clear the PR5 code?

Flip the circuit breaker off and leave it for a full 60 seconds. Not the button on the control panel, the actual breaker in your box. This clears the board's fault memory completely. Turn it back on, let the machine power up, then run a short cycle. If PR5 comes back within a minute, the underlying cause is still there. A reset that holds for one or two full cycles but then returns usually means a switch that's right on the edge of failing, so don't put off replacing it.

Frequently Asked Questions

What is the difference between PR5 and FED on a GE dishwasher?

PR5 is an electrical problem where the board can't get a valid signal from the pressure switch at all. FED is a logic problem where the sensor works fine but the board can't confirm the water drained at the end of the cycle. Both use the exact same WD01X24700 switch, so if you're replacing it for PR5 you're also covering yourself for FED at the same time. The timing tells you everything. PR5 fires at the start of the cycle, FED fires at the end. That's the fastest way to tell them apart.

How much does it cost to fix the PR5 code?

If it's just the air tube, you're looking at basically nothing. A foot of replacement tubing is a dollar or two at any hardware store. The pressure switch itself, part WD01X24700, runs about $25-30 online. If you call a tech out, expect $150-250 for the service call and labor on top of the part. Honestly the repair itself is maybe 45 minutes once you know what you're looking at, and most people can handle it themselves without any special skills.

Will the PR5 code go away on its own?

No. This isn't a random glitch. If it came up, the board detected a real problem in the pressure sensor circuit and it's not going to clear itself. You can reset the breaker and it might run a cycle or two before coming back, especially if the switch is intermittently failing, but that's not a fix. Don't keep trying to reset it hoping it goes away. You could end up masking a switch that's about to fail completely, and eventually it'll lock out for good or worse, let the tub overfill.

Can I run my dishwasher with a PR5 code showing?

I wouldn't. The code locks the cycle specifically because the machine can't confirm how much water is in the tub. Without that info it doesn't know whether to keep filling, stop filling, or drain. Run it blind and you risk the fill valve staying open too long and flooding your kitchen floor. The repair is cheap and honestly pretty quick. It's not worth the water damage risk to skip it.

How do I know if it's the air tube or the actual switch that's bad?

Start with the tube, always. It's free to check and it's the cause maybe 60% of the time based on what I see in the field. If the tube is attached, intact, and clear when you blow through it, then move on to the switch test with your multimeter. A switch that won't change state when you blow into the inlet port has a failed diaphragm and needs to be replaced. If both test fine and you're still getting PR5, that's when you start tracing the wiring harness back toward the control board.
