GE Dryer Error Code 8

Pressure Sensor Loss

GE codesGE dryer codes

Pressure Sensor Loss - Too great of a difference in the pressure sensor reading and the expected pressure sensor reading for the amount of water the control calculated it has put in. Assumes pressure leak, clog in pressure hose/system, or significant water leaking out.

First step from the service manual

Check to make sure house water supply valves are turned on. Check water valve operation. Check pressure tube for pinches where it goes through top cover grommet.

What 8 means on a GE dryer

Error code 8 on a GE dryer indicates a Pressure Sensor Loss fault. This occurs when the control board detects a significant discrepancy between the actual pressure sensor reading and the expected reading based on the calculated volume of water the control has dispensed. The pressure sensing system is used to monitor water levels inside the drum or reservoir during steam or moisture-related cycles. When the measured pressure falls too far outside the predicted range, the control interprets this as a system failure and triggers the error.

The fault points to one of three underlying conditions: a pressure leak in the sensing system, a blockage or pinch in the pressure hose or related tubing, or water physically escaping the system, meaning the water that was delivered is not accumulating as expected. A kinked or pinched pressure tube, particularly at the point where it passes through the top cover grommet, is a very common physical cause. If the tube is deformed at that transition point, pressure readings will be unreliable or absent.

Diagnosis should begin by confirming that the household water supply valves feeding the dryer are fully open. Inadequate water supply pressure or flow can prevent the system from filling correctly, causing the sensor reading to lag behind the control's expectations. After confirming water supply, the water inlet valve itself should be tested for proper operation. Then the pressure tube routing should be physically inspected for kinks, pinches, or disconnections, especially at the grommet penetration in the top cover.

Common causes of 8

  1. 01

    Closed or restricted house water supply valve

    Wiring / connection

    If the water supply valve feeding the dryer is partially or fully closed, insufficient water enters the system and the pressure sensor reading will not match the control's expectations. Verify both hot and cold supply valves are fully open.

  2. 02

    Pinched or kinked pressure tube at top cover grommet

    Wiring / connection

    The pressure hose commonly becomes pinched where it passes through the grommet in the top cover. A deformed tube at this point restricts pressure transmission, causing inaccurate sensor readings. Inspect and straighten or reposition the tube at this location.

  3. 03

    Clogged pressure hose or pressure system

    Wiring / connection

    Mineral deposits, debris, or moisture buildup can clog the pressure tube or sensing port, blocking accurate pressure readings from reaching the sensor. Disconnect the tube and inspect for obstructions.

  4. 04

    Faulty water inlet valve

    Part replacement

    If the water inlet valve is not opening fully or is failing intermittently, the dryer will not receive the expected volume of water. Testing the valve for proper solenoid resistance and flow is required to rule this out.

  5. 05

    Water leaking from internal components

    Part replacement

    If water is escaping the system through a cracked hose, loose connection, or damaged internal component, the pressure sensor will not reflect the amount of water the control calculated it dispensed. Inspect all internal water lines and connections for signs of moisture or dripping.

Frequently asked questions about 8

What does 8 mean on a GE dryer?
Error code 8 on a GE dryer signals a Pressure Sensor Loss fault. The control board has detected that the pressure sensor reading does not match what it expected based on the amount of water it calculated it put into the system. This points to a pressure leak, a clog or pinch in the pressure hose, or water leaking out of the system internally. Checking the water supply valves and the pressure tube routing are the recommended first steps.
Can I fix error code 8 on my GE dryer myself?
Some causes of error code 8 can be addressed without professional help. Start by confirming the household water supply valves are fully open, then locate and inspect the pressure tube for pinches, especially where it passes through the top cover grommet. If the tube is kinked, repositioning it may clear the fault. If the water inlet valve is faulty or internal water leaks are present, those repairs typically require replacement parts and more advanced disassembly.
Is it safe to keep using my GE dryer when error code 8 appears?
Continuing to operate the dryer while error code 8 is active is not recommended. The fault indicates the water management system is not functioning correctly, which could mean water is leaking inside the unit. Running the dryer under these conditions risks water damage to internal electrical components or surrounding cabinetry.
Will resetting my GE dryer clear error code 8?
A power reset may temporarily clear the displayed code, but if the underlying issue is not resolved, the error will return once the dryer attempts to use the water system again. The root cause, whether a supply valve, pressure tube obstruction, or component failure, must be identified and corrected for the fault to stay cleared.
How much does it cost to repair error code 8 on a GE dryer?
Repair costs depend on the cause. If the fix is simply opening a water supply valve or repositioning a kinked pressure tube, there is no parts cost involved. A replacement water inlet valve typically costs between $20 and $60 for the part, with additional labor costs if a technician is needed. If internal water leaks have damaged other components, overall repair costs could range from $100 to $300 or more depending on what is affected.
