Huebsch Washer Error Code E PS: Pressure Sensor Error
E PS on Huebsch Quantum toploads and QN washer-extractors means the control is not getting a valid reading from the sensor that measures water level. Cut power, restore it, and watch whether a level reading comes back. If E PS stays, let us schedule service.
Medium: without a level reading the washer cannot control filling, so it stops or declines to go on.
What does Huebsch error code E PS mean?
The washer cannot fill or drain with confidence unless it knows how much water is in the tub, and that comes from a pressure sensor connected to the tub by a small air tube. When the control stops getting a valid reading from that sensor, and on the QN models that lasts 30 seconds, it displays "E PS". The washer may stop filling partway, run past its level, or decline to go on. The manual points to water or a kink in the air tube leading to the sensor, a loose or corroded wire at the sensor connector, and a sensor that stopped sending a level reading. In a laundry the air tube can pick up moisture or lint, and the manual also suggests confirming the cabinet sits level on its feet, without tipping or lifting it.
Affected models and control systems
This page covers Huebsch Quantum topload washers in the TLW13C family and QN washer-extractors with the CHM1792C front-end control. The 30-second detection time applies to the QN models.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Washer stops filling partway or runs past its level
- "E PS" on the display
- Cycle will not go on to the next step
Possible causes
Listed in Huebsch's documentation
- Water or a kink in the air tube leading to the sensor
- Loose or corroded wire at the sensor connector
- Pressure sensor no longer sending a level reading
Other likely causes — what usually sits behind error code E PS on this control. A technician confirms which one it is before any part is replaced.
- Lint packed into the sensor port or tube from a heavy linen load
- A connector corroded by the damp air around a laundry drain
Safe checks before calling for service
- Cut power, restore it, and watch whether a level reading comes back.
- Check that the cabinet sits level on its feet, without tipping or lifting it.
- Never put anything into the sensor tube or port.
- If E PS stays, let us schedule service and describe what the water level was doing.
How a technician diagnoses error code E PS
- Read the code and note the tub level at the time.
- Inspect the air tube for water, kinks and leaks.
- Check the sensor connector for corrosion and tightness.
- Read the sensor signal as the level changes.
- Replace the sensor or tube only after the signal test fails.
- Reading the sensor signal means the control is live with the cabinet open.
- Clearing a blocked port with the wrong tool can damage the sensor.
- Corroded connectors need cleaning and inspection at the board.
How error code E PS differs from similar codes
E PS is a missing level reading, which is different from E LP and E Pr, the pressure switch messages tied to the production test cycle.

Related Huebsch washer error codes
Can I blow into the tube to clear it?
No. Never put anything into the sensor tube or port.
Is this a leak?
Not by itself. The control cannot read the level, which is not the same as water escaping.
Will it go away when the machine dries out?
Moisture in the tube can clear, but a repeat means the sensor or wiring needs testing.
