What E Pr means on a Speed Queen washer

The E Pr code on a Speed Queen washer is an informational counter rather than a standard fault code. It tracks the number of times power has been interrupted mid-cycle during the life of the machine. Each time the washer loses power while a wash cycle is actively running, whether from a tripped breaker, a power outage, a loose cord, or the machine being manually unplugged, the counter increments by one. The display shows this accumulated count so technicians can assess the machine's power stability history.

This code is diagnostic in nature and does not necessarily indicate a component failure. However, a high count can be a useful flag during a service call. Frequent power interruptions during cycles can stress the control board, motor, and drive components over time, since these interruptions prevent the machine from completing its normal shutdown sequence. If the count is unusually high, it warrants investigating the quality of the electrical supply, the condition of the outlet and power cord, and whether the household circuit is properly rated for the washer's load.

Technicians encountering E Pr should treat it as contextual information when diagnosing other issues. A single-digit count is generally unremarkable. A count in the dozens or higher suggests recurring power instability and should prompt a closer look at the branch circuit, breaker condition, and cord connections at both the outlet and the terminal block on the machine.

Common causes of E Pr

  1. 01

    Household power outages

    Wiring / connection

    Utility power interruptions during an active cycle will increment the E Pr counter. If your area experiences frequent brief outages or voltage sags, the count can rise quickly without any fault in the washer itself.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    An overloaded or weak breaker that trips during operation will cut power mid-cycle and add to the E Pr count. Check the breaker for proper rating and signs of wear or heat damage.

  3. 03

    Loose or damaged power cord connection

    Part replacement

    A power cord that is partially pulled from the outlet or has a damaged plug can cause intermittent power loss during operation. Inspect the cord, plug prongs, and outlet for damage or poor contact.

  4. 04

    Machine manually unplugged or switched off mid-cycle

    Wiring / connection

    If the washer is regularly unplugged or the outlet switch is turned off before a cycle completes, each instance adds to the counter. This is a normal operational cause and does not indicate a fault.

  5. 05

    Faulty wall outlet

    Wiring / connection

    A receptacle with loose internal contacts can intermittently drop the connection under load. Testing the outlet with a voltmeter or swapping to a known-good circuit can confirm this cause.

Frequently asked questions about E Pr

What does E Pr mean on a Speed Queen washer?
E Pr is a power interruption counter built into the Speed Queen washer's control system. It records the total number of times power was cut to the machine while a wash cycle was in progress. It is an informational display, not a fault alarm, and does not mean the washer is broken.
Will resetting the washer clear the E Pr count?
The E Pr counter is stored in the control board's memory and is designed to persist across power cycles so technicians can review the machine's history. A simple unplug-and-replug reset will not clear this count. Clearing the stored value typically requires a specific button sequence or service mode access as outlined in the technical documentation for your model.
Is it safe to keep using the washer when E Pr is displayed?
Yes, in most cases the washer is safe to use. E Pr is a historical log, not an active fault, so the machine will generally continue to operate normally. However, if the count is rising rapidly, you should investigate your home's electrical supply to prevent potential stress on the washer's control board and motor over time.
How do I fix the E Pr code on my Speed Queen washer?
Because E Pr is a counter and not a component fault, there is nothing to repair in the traditional sense. Focus instead on preventing future power interruptions by checking your circuit breaker, inspecting the power cord and outlet, and ensuring the washer is on a properly rated dedicated circuit. If the count is increasing rapidly, addressing those electrical issues will stop it from climbing further.
How much does it cost to address the issues behind a high E Pr count?
Costs depend heavily on the root cause. Replacing a power cord typically runs in the range of $15 to $40 for parts. Having an electrician inspect or replace a faulty outlet or breaker generally costs $75 to $200 depending on your location and the work required. If the control board has been damaged by repeated power interruptions, board replacement can cost $150 to $400 or more including labor.
