What E5 means on a Hoover washer

The E5 error code on a Hoover washer indicates an open circuit in the motor tacho coil. The tacho coil, also called a tachometer generator, is a small winding mounted on the rear of the wash motor. Its function is to generate a low-voltage AC signal proportional to motor speed, which the control board uses to regulate drum rotation throughout the wash, rinse, and spin cycles. When the control board detects no signal or an interrupted signal from the tacho coil, it cannot confirm the motor is running at the correct speed and triggers E5 to halt operation.

An open circuit in the tacho coil means the electrical path through the coil winding is broken, preventing any signal from reaching the control board. The expected resistance across a healthy tacho coil is approximately 170 ohms. A reading significantly above this range or an open-line (OL) reading on a multimeter confirms the coil winding has failed internally. In addition to coil failure, broken or disconnected wiring between the tacho coil and the control board can produce the same fault, as can corroded connector pins or a damaged harness caused by drum movement over time.

Diagnosis begins at the tacho coil itself. With the machine unplugged, the connector at the coil should be removed and resistance measured across the two coil terminals. A reading near 170 ohms indicates the coil is intact and the fault likely lies in the wiring harness or connectors running back to the control board. A reading well outside this value, or no continuity at all, points to a failed tacho coil requiring replacement. The wiring harness should also be inspected for chafing, pinching, or loose terminals before condemning any component.

Common causes of E5

  1. 01

    Failed tacho coil winding

    Part replacement

    The coil winding inside the tachometer generator can break internally due to age or heat, resulting in an open circuit. Confirm by measuring resistance across the coil terminals: any reading well above or far below 170 ohms, or an open-line reading, indicates a failed coil.

  2. 02

    Broken or disconnected wiring harness

    Wiring / connection

    The wires running from the tacho coil to the control board can break, chafe against the drum or cabinet, or pull loose from connectors due to vibration. Inspect the full length of the harness for damage and check that both connector ends are fully seated.

  3. 03

    Corroded or damaged connector pins

    Wiring / connection

    Moisture inside the machine can corrode the connector pins at either end of the tacho coil circuit, increasing resistance enough to interrupt the signal. Inspect connectors for discoloration, oxidation, or bent pins and clean or replace as needed.

  4. 04

    Loose tacho coil mounting

    Wiring / connection

    The tacho coil is mounted to the motor and must remain correctly positioned relative to the rotor magnet. If the coil has shifted or its mounting has loosened, the signal can be lost even if the coil winding tests correctly.

  5. 05

    Faulty motor control board

    Part replacement

    If the tacho coil and all wiring test within specification, the control board circuit responsible for reading the tacho signal may have failed. This is the least likely cause and should only be considered after all wiring and the coil itself have been ruled out.

Frequently asked questions about E5

What does E5 mean on a Hoover washer?
E5 on a Hoover washer signals an open circuit in the motor tacho coil. The tacho coil is a sensor on the motor that monitors drum speed. When the control board receives no signal from this coil, it stops the machine and displays E5. The fault can be in the coil itself, the wiring harness, or the connectors linking them.
Can I fix a Hoover E5 error myself?
A knowledgeable DIYer can perform basic diagnosis by unplugging the machine, locating the tacho coil on the rear of the motor, and measuring resistance across its terminals with a multimeter. The target reading is approximately 170 ohms. Checking for loose connectors or visibly damaged wiring is also within reach for most home repair enthusiasts, though replacing internal motor components may require professional assistance.
Will resetting the washer clear the E5 error?
Resetting the machine by unplugging it for several minutes may temporarily clear the error code, but the fault will return as soon as the control board attempts to read the tacho signal again. A reset does not address the underlying open circuit. The tacho coil and its wiring must be tested and repaired before the machine will function normally.
Is it safe to use my Hoover washer when E5 is displayed?
The machine will typically stop operation when E5 is active, and continuing to attempt running it without resolving the fault is not recommended. Without a working tacho signal, the control board cannot regulate motor speed, which could lead to incorrect spin speeds or unpredictable motor behavior. The washer should remain out of service until the fault is diagnosed and corrected.
How much does it cost to repair a Hoover E5 error?
Repair costs depend on what component has failed. If only the wiring or connectors need attention, costs may be minimal. Replacing a tacho coil or motor assembly typically involves parts costs in the range of $30 to $120 depending on the specific model, plus any labor charges if a technician is engaged. A full motor control board replacement would generally fall at the higher end of the cost range.
