GE Washer Error 27: Pressure Sensor or Water Level Fault

Quick Answer

GE washer Error 27 is a pressure sensor fault. The water level switch is not reporting a valid reading to the control board. Start by checking the small air hose connecting the pressure sensor to the tub - a clog or disconnect here is the most common cause.

The water level switch is not reporting a valid reading to the control board. Start by checking the small air hose connecting the pressure sensor to the tub - a clog or disconnect here is the most common cause. If the air hose is clear, test the sensor and replace it if faulty.

What Does the Error 27 Code Mean?

Pressure sensor (water level sensor) reading is out of expected range or not communicating with the control board. Causes include clogged air hose, failed sensor, or excessive suds.

Most Likely Causes

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

Pressure sensor failed or out of calibration range40%
Air hose between tub and sensor clogged, kinked, or disconnected24%
Excessive suds from non-HE or overdosed detergent14%
Control board not reading sensor signal correctly12%
Moisture or mold inside the air hose interfering with pressure10%

Symptoms You May Notice

  • Error 27 on control panel display
  • Washer overfills or underfills and stops
  • Cycle pauses at fill phase without completing
  • Machine fills to incorrect water level for cycle selected
  • Washer stops immediately after fill starts

Can you reset a Ge washer to clear the Error 27 code?

After repairing the air hose connection or replacing the pressure sensor, unplug the washer for 60 seconds to clear Error 27 from memory. Reconnect power and run a test cycle.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

Locate the pressure sensor

Locate the pressure sensor. On GFW front-load models it is typically in the upper right area of the cabinet, accessible after removing the top panel. On GTW top-load models, it is near the top under the control panel. Trace the air hose from the sensor down to the tub.

2

Disconnect the air hose from the pressure sensor

3

Test the pressure sensor directly

4

Check the tub connection point where the air hose attaches to

5

After repairing the air hose or replacing the sensor

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is the pressure sensor on a GE washer?
The pressure sensor (also called the water level switch or pressure switch) detects how much water is in the drum by measuring air pressure in a sealed tube connected to the tub. As water rises, it compresses air in the tube. The sensor converts that pressure change into an electrical signal the control board reads to determine water level.
Can I clean the pressure sensor air hose myself?
Yes. Disconnect both ends of the air hose (sensor port and tub port). Flush the hose with warm water to dissolve soap residue. Use a thin pipe cleaner to clear any stubborn buildup. Blow air through it to confirm it is clear before reconnecting. The hose typically costs under $10 to replace if it is too clogged or damaged.
How is Error 27 different from Error 18 on a GE washer?
Error 18 specifically means an overflow condition was detected. Error 27 means the pressure sensor is out of its expected range entirely - it may be reading too high, too low, or not at all. Error 27 does not necessarily mean the drum is overfull; it means the sensor cannot give the control board a usable reading.
Will excessive soap suds cause Error 27?
Yes. If foam from too much detergent or non-HE soap gets into the air hose, it partially blocks the pressure tube and sends an incorrect reading to the sensor. This is most common after switching detergent brands or exceeding the recommended dose. Run a clean rinse cycle with no detergent and flush the air hose if suds are suspected.
Is Error 27 the same as the washer overfilling?
Not necessarily. Error 27 is a sensor communication fault - the sensor is not reporting correctly. The machine may not have actually overfilled. If the drum looks empty or at a normal level and Error 27 appears, the issue is with the sensor or its air hose, not with actual excess water.
