What 27 means on a GE washer dryer
Error code 27 on a GE washer/dryer combination unit indicates a water accessibility fault. Specifically, the control detects that water has remained in the tub while the lid has been left open for more than 15 minutes. The machine monitors this condition through its pressure sensor, which tracks the water level inside the basket at all times. When the sensor reports standing water and the lid-open condition persists beyond the 15-minute threshold, the control board logs error 27 to alert the user and halt normal operation.
The pressure sensor is the central component in diagnosing this fault. It outputs a voltage signal that corresponds to the water level inside the basket. Technicians should consult the pressure sensor chart for the specific unit to confirm the output voltage aligns with the actual water level present. A mismatch between the sensor's output voltage and the true water level suggests either a faulty pressure sensor, a blocked or kinked pressure hose, or a failed air trap at the base of the tub that prevents accurate pressure readings from reaching the sensor.
Additional causes can include a drain pump that failed to evacuate water before the lid was opened, a clogged drain path such as a blocked pump filter or obstructed drain hose, or a control board that is misinterpreting sensor signals. In some cases, the lid switch or lid-position sensor may be reporting the lid as open when it is actually closed, causing the timer to trigger incorrectly. Systematic testing of the pressure sensor output voltage against the pressure chart is the recommended starting point before moving on to drain system components.

Common causes of 27
- 01
Faulty or miscalibrated pressure sensor
Part replacementIf the pressure sensor's output voltage does not match the actual water level shown on the pressure sensor chart, the sensor itself may be defective or out of calibration. Compare the sensor's voltage reading directly to the chart for the unit to confirm.
- 02
Blocked or kinked pressure sensor hose
Wiring / connectionThe hose connecting the air trap to the pressure sensor can become kinked, clogged with debris, or disconnected, causing inaccurate water level readings. Inspect the hose along its entire length for obstructions or damage.
- 03
Drain pump failure or clogged drain path
Part replacementIf the drain pump has failed or the drain filter or hose is blocked, water will remain in the tub after a cycle. Check the pump for operation and inspect the filter and drain hose for obstructions.
- 04
Lid switch or lid-position sensor fault
Part replacementA faulty lid switch or lid-position sensor can incorrectly report the lid as open when it is closed, triggering the 15-minute timer prematurely. Test the lid switch for continuity and confirm the sensor is reading the lid position accurately.
- 05
Control board misinterpreting sensor signals
Part replacementIn less common cases, the main control board may fail to correctly process the pressure sensor output, causing it to log error 27 even when water levels and lid position are normal. This is typically diagnosed after all other components have been ruled out.
