What E98 means on a Electrolux washer

The E98 error code on an Electrolux washer signals a communication failure between the main control board and the inverter board. The inverter board is responsible for controlling motor speed and direction by converting incoming AC power into variable-frequency DC output. The main control board sends operational commands to the inverter board via a dedicated communication circuit, and when that signal exchange breaks down or cannot be confirmed, the washer halts operation and triggers E98.

The most common entry point for this fault is a loose or improperly seated connector. The wiring harness connecting these two boards can work itself free over time due to vibration from normal wash cycles. A failed connector will interrupt the data signal entirely, producing the same error as a fully defective board. This is why inspecting and reseating the connectors on both the main control board and the inverter board is the recommended first diagnostic step.

If the connectors are secure and the wiring harness shows no visible damage, breaks, or corrosion, then component-level failure becomes the likely cause. Either the main control board or the inverter board itself may have failed internally, losing the ability to send or receive communication signals. Determining which board is at fault typically requires measuring supply voltages and verifying signal continuity through the harness before condemning either component.

Common causes of E98

  1. 01

    Loose or unseated wiring connectors

    Wiring / connection

    The connectors linking the main control board and inverter board can loosen from vibration over time. Inspect both connectors and firmly reseat them, then run a cycle to see if the error clears.

  2. 02

    Damaged wiring harness

    Part replacement

    The harness between the two boards may have chafed, corroded, or broken wires that interrupt the communication signal. Visually trace the harness for pinched sections, burned insulation, or corroded terminals.

  3. 03

    Defective inverter board

    Part replacement

    The inverter board may have failed internally and can no longer send or receive signals from the main control board. If wiring checks out, the inverter board is the more likely failed component of the two boards.

  4. 04

    Defective main control board

    Part replacement

    The main control board itself may have failed, losing the ability to communicate with the inverter board. This is typically confirmed only after ruling out wiring faults and inverter board issues.

Frequently asked questions about E98

What does E98 mean on a Electrolux washer?
E98 indicates a communication error between the main control board and the inverter board. The washer stops operation because the two boards can no longer exchange data signals reliably. The fault can stem from a loose connector, a damaged wiring harness, or a defective board on either end of the communication circuit.
Can I fix E98 on my Electrolux washer myself?
If the cause is a loose connector, you may be able to resolve it yourself by unplugging the washer, locating the harness connections at both boards, and firmly reseating them. However, if the wiring harness is damaged or a board has failed internally, component replacement is required and is best handled by a qualified technician. Working inside the cabinet involves exposure to capacitors and line-voltage components, so use caution and always disconnect power first.
Is it safe to use my Electrolux washer when E98 is displayed?
No, you should not continue running the washer while E98 is active. The control system has halted operation specifically because a critical communication link has failed, and running the machine in this state could cause further damage to the motor control components. Disconnect the washer from power until the fault is diagnosed and corrected.
How much does it cost to repair an E98 error on an Electrolux washer?
Repair costs vary depending on which component is at fault. If only a connector needs reseating, the repair may cost nothing beyond a service call fee, typically in the range of $75 to $150. If the inverter board or main control board requires replacement, parts and labor combined can range from $200 to $500 or more depending on your location and the specific model.
Will resetting my Electrolux washer clear the E98 error?
A power reset by unplugging the washer for several minutes may temporarily clear the code, but if the underlying wiring or board fault is still present, the error will return during the next cycle. A reset is useful as a first step to rule out a transient software glitch, but a persistent E98 code requires hands-on diagnosis of the connectors, harness, and boards.
