What Er, PS means on a Speed Queen washer

The Er, PS error code on a Speed Queen washer indicates the control board has detected a fault in the pressure sensing circuit responsible for monitoring water fill level. The pressure sensor, sometimes called a water level sensor or pressure switch, works by detecting air pressure changes in a small tube connected to the tub. As water fills the tub, it compresses air in this tube, and the sensor translates that pressure into a signal the control board reads to determine the current water level. When the control cannot get a reliable reading from this system, it logs the Er, PS fault and halts operation.

Common causes of this fault include a failed pressure sensor, a kinked or disconnected pressure hose between the sensor and the tub, or a clogged pressure port at the tub connection. Wiring issues between the pressure sensor and the control board, such as loose connectors or damaged wire harness segments, can also trigger this code. In some cases, the control board itself may be at fault if it cannot properly interpret the sensor signal.

Because diagnosing this code involves inspecting internal wiring, the pressure hose routing, and potentially testing sensor resistance or continuity, Speed Queen's recommended first step is to unplug the machine and contact a qualified service technician. Attempting to run the washer with an unreliable water level sensor risks overfilling the tub, which can cause water damage or secondary component failures.

Common causes of Er, PS

  1. 01

    Failed pressure sensor

    Part replacement

    The pressure sensor itself may have failed internally and is no longer sending a valid signal to the control board. This is the most frequent hardware failure associated with this code and typically requires sensor replacement.

  2. 02

    Kinked or disconnected pressure hose

    Wiring / connection

    The small air hose connecting the pressure sensor to the tub can become kinked, cracked, or disconnected over time. A technician can visually trace this hose to check for damage or improper routing.

  3. 03

    Clogged pressure port at the tub

    Wiring / connection

    The port where the pressure hose connects to the tub can become blocked with detergent residue or debris, preventing accurate pressure readings. Clearing this blockage may restore normal sensor operation.

  4. 04

    Wiring harness fault

    Wiring / connection

    Loose connectors, corroded terminals, or damaged wiring between the pressure sensor and the control board can interrupt the sensor signal. A technician will inspect and test continuity along this circuit.

  5. 05

    Faulty control board

    Part replacement

    If the pressure sensor and all associated wiring test correctly, the control board may be unable to process the sensor input properly. Control board replacement is typically a last-resort diagnosis after other causes are ruled out.

Frequently asked questions about Er, PS

What does Er, PS mean on a Speed Queen washer?
Er, PS means the control board has detected a problem with the pressure sensing system that monitors the water fill level inside the tub. The washer stops operation to prevent overfilling or running without proper water level data. The fault can originate from the pressure sensor, the connecting hose, related wiring, or the control board itself. Speed Queen advises unplugging the machine and calling a qualified technician for diagnosis.
Can I fix the Er, PS error code myself?
Speed Queen's recommended first step for this code is to unplug the machine and call for service, as diagnosis involves inspecting internal components like the pressure hose, sensor, and wiring harness. A knowledgeable DIYer comfortable working inside appliances could visually check the pressure hose for kinks or disconnections, but testing the sensor and wiring properly requires a multimeter and familiarity with the wiring circuit. If you are not confident working with appliance internals, professional service is the safer path.
Is it safe to keep using my washer with an Er, PS code?
No, you should not continue running the washer while this code is active. Without a reliable water level reading, the control board cannot properly regulate the fill cycle, which creates a risk of tub overfilling and potential water damage to your home or secondary machine components. Unplug the washer until the fault has been properly diagnosed and repaired.
Will resetting the washer clear the Er, PS error code?
A power cycle reset may temporarily clear the code from the display, but it will not resolve the underlying hardware or wiring fault causing the pressure sensing failure. The code is very likely to return as soon as the washer attempts to fill again. A proper repair addressing the root cause is necessary for the code to stay cleared.
How much does it cost to repair an Er, PS error on a Speed Queen washer?
Repair costs vary depending on the root cause identified by the technician. If only the pressure hose needs to be reseated or cleared, the cost may primarily be a service call fee, typically in the range of $75 to $150. Replacing the pressure sensor itself generally adds $30 to $100 in parts. A control board replacement, if required, is a more significant repair and could push total costs into the $200 to $450 range depending on labor rates in your area.
